Fixing Your 2020 Tacoma's Steering Problems

How to Fix Steering Rack Replacement

For 2020 Toyota Tacoma owners, addressing steering-related issues often involves understanding the components that connect you to the road. While a full steering rack replacement is a significant job, many owners report symptoms that lead them to investigate the steering system, from worn-out steering wheels to concerns about steering feel and component longevity. As one owner shared about a different but related DIY project: "If i never touch a needle and thread again, it will be too soon. 10/10 do not recommend this diy mod. Just buy a new steering wheel or have it professionally upholstered." This sentiment highlights the complexity that can accompany steering system work, setting the stage for understanding what it takes to tackle a major component like the rack.

Symptoms

Owners of this truck report a variety of steering and handling sensations that can point toward issues within the steering system, potentially culminating in the need for rack inspection or replacement. A common complaint is a steering wheel that is physically wearing out, becoming smooth, shiny, or cracked, which directly impacts your grip and comfort. "My steering wheel is getting worn out to the point its noticeable and annoying as," one owner noted, highlighting how a primary control surface's degradation is often the first noticeable symptom.

Beyond the wheel itself, unusual steering behavior is a key indicator. Some drivers describe a sensation where the truck feels like it's being pulled or corrected without their input. This is often linked to electronic steering aids. "That’s the active lane assist if it detects you are leaving your lane (or what it thinks your lane is ) it will automatically turn the wheel to correct it," explained an owner, describing a feature that can sometimes feel intrusive or like a problem if not understood. On mixed surfaces or during specific maneuvers, you might find the steering feels unusually heavy or vague, prompting investigation into the mechanical linkages. Another owner pointed out, "I'd say, try it, and if you have a hard time steering, then turn it off. Unfortunately this is where having 4hi/lo doesn't shine," referring to testing drive modes but underscoring that changes in steering effort are noteworthy.

Finally, concerns about long-term durability and preventative maintenance for steering components are prevalent among high-mileage drivers. The focus shifts from immediate symptoms to preventing failure. Advice from seasoned owners emphasizes proactive care: "Replace with greasable joints when possible and make sure you actually lube them and you'll see an increase in life span." This proactive approach is often born from experiencing or anticipating the symptoms of worn tie rod ends, ball joints, or a failing steering rack itself, such as loose steering, clunks over bumps, or fluid leaks from the rack's seals.

Most Likely Cause

Based on owner discussions and experiences, the most likely primary cause leading to steering rack consideration or replacement is the cumulative wear and tear on steering system joints and seals, accelerated by a lack of preventative maintenance. The steering rack is the central gearbox that translates your wheel input into lateral movement of the front wheels. It contains precision gears and is sealed with fluid (in hydraulic systems) or has internal electric motors (in EPS systems). While the 2020 Tacoma uses an Electric Power Steering (EPS) system, eliminating power steering fluid, the rack itself still has internal gears and is connected to the wheels via tie rods.

The root cause of failure often starts at these connection points. The tie rod ends are ball-and-socket joints that allow for movement and pivoting. As one owner wisely stated, "There's other brands that will most likely last longer but will all fail eventually." These joints, along with other linkage points, are subject to constant stress, road vibrations, and exposure to elements. When they are not serviceable (greasable), they run dry and wear out faster. This wear creates slack, or "play," in the steering system. This play forces the internal gears of the steering rack to handle uneven forces and minor impacts they weren't designed for, accelerating wear on the rack's internal components. Therefore, while the rack itself may be robust, the failure of its connected components and lack of lubrication is the most cited pathway to needing a rack service or replacement.

How to Diagnose

Diagnosing a potential steering rack issue requires a systematic approach to isolate the problem. You'll need a few basic tools: a jack and jack stands to safely lift the front end, a flashlight, and a helper.

Step 1: Visual and Physical Inspection of the Steering Wheel. Start inside the cab. Examine your steering wheel for the wear described by owners. While this doesn't diagnose the rack, it confirms general steering system age and use. Grab the wheel firmly and try to rock it up, down, left, and right. There should be absolutely no movement before you feel the steering column engage. Any clunk or movement here indicates a worn steering shaft U-joint or column bearing, not the rack.

Step 2: Test Drive for Feel. Drive the truck on a safe, straight, and level road. Note if the steering feels loose, has excessive play (where you turn the wheel but the truck doesn't immediately respond), or if it pulls to one side. Test on a smooth parking lot by turning the wheel lock-to-lock. Listen for any grinding, clicking, or binding sensations. Remember that electronic features like Lane Departure Alert can cause automatic corrections; ensure this is turned off for diagnosis.

Step 3: Inspect Tie Rods and Linkage. With the front wheels lifted and securely supported on jack stands, have your helper sit in the driver's seat with the engine on (so power steering is active). Stand in front of one wheel. Have your helper slowly turn the wheel left and right just a few degrees. Watch the tie rod where it connects to the steering knuckle. Any visible movement or clunking at the joint before the wheel moves indicates a bad tie rod end. Now, grab the tire at the 9 o'clock and 3 o'clock positions and try to shake it vigorously in and out. If you feel a clunk and see movement, the tie rod end or ball joint is likely worn. This test helps determine if the problem is in the linkage rather than the rack.

Step 4: Isolate the Rack. If the tie rods and ball joints are tight, the issue may be internal to the rack. With the wheels still off the ground, have your helper gently turn the wheel while you place a hand on the rubber bellows (boots) at each end of the steering rack. Feel for any gritty vibration or clicking that transmits through the boot. This can indicate worn internal gears. Also, inspect the boots for tears or leaks; while the Tacoma's EPS doesn't use fluid, torn boots allow dirt and moisture to enter and destroy the rack's internal seals and gears.

Step-by-Step Fix

Replacing the steering rack on a 2020 Toyota Tacoma is an advanced DIY project that requires mechanical skill, proper tools, and an alignment must be performed afterward. This guide outlines the major steps based on standard procedure and owner insights on component care.

1. Preparation and Safety. Park on a level surface, engage the parking brake, and chock the rear wheels. Disconnect the negative battery terminal. Lift the front of the truck using a quality floor jack and support it securely on jack stands rated for the vehicle's weight. Remove the front wheels.

2. Access the Steering Components. You may need to remove underbody skid plates or the "cat guard" mentioned by owners for access. Locate the steering rack, which is mounted across the vehicle behind the front axle. Disconnect the electrical connector for the Electric Power Steering (EPS) motor attached to the rack.

3. Disconnect the Tie Rods. Straighten the front wheels. Remove the cotter pin and castle nut from the outer tie rod end where it connects to the steering knuckle. Use a tie rod separator or "pickle fork" to pop the tapered stud loose from the knuckle. Do this for both sides. As one owner shared about working on steering components: "Replace with greasable joints when possible and make sure you actually lube them and you'll see an increase in life span." This is the perfect time to upgrade to serviceable tie rod ends if desired.

4. Disconnect the Steering Shaft. From inside the engine bay, locate where the lower steering shaft connects to the pinion input of the steering rack. There is typically a pinch bolt or U-joint clamp. Loosen and disconnect this coupling. This separates the steering wheel from the rack.

5. Remove the Rack Mounting Bolts. The rack is held to the subframe or crossmember by two or three mounting brackets with bolts. Support the rack with one hand or a jack, then remove these bolts carefully.

6. Install the New Rack. Maneuver the old rack out. Installation is the reverse of removal. Carefully guide the new rack into position. Hand-thread all mounting bolts before tightening them to the factory specification. Reconnect the steering shaft coupling and tighten its bolt. Reconnect the EPS motor electrical connector.

7. Install New Tie Rods and Set Toe. It is highly recommended to install new inner and outer tie rods with the new rack. Screw the new tie rods onto the rack ends, but only hand-tight for now. Connect the outer tie rod ends to the steering knuckles and torque the castle nuts, installing new cotter pins. Critical: Before lowering the truck, you must get a preliminary toe setting. Measure the distance between the front edges of the front wheels and the rear edges. Adjust the tie rods (by turning them) to get the wheels pointing perfectly straight. This is only a rough setting to make the truck drivable to an alignment shop.

8. Final Steps. Reinstall wheels, skid plates, and lower the truck. Reconnect the battery. You must take the truck for a professional wheel alignment immediately. The alignment technician will set the toe angle precisely and check caster/camber. Test drive carefully, noting that the steering may feel very sensitive until the alignment is complete.

Parts and Tools Needed

Parts:

• Steering Rack Assembly (EPS) for 2020 Toyota Tacoma - Part numbers vary by trim (e.g., 44250-04080, confirm with your VIN).
• Inner Tie Rods (Left & Right) - Often included with a remanufactured rack, but sold separately (e.g., 45503-04050).
• Outer Tie Rod Ends (Left & Right) - Consider greasable/Serviceable versions (e.g., Moog ES800491).

Real Owner Costs

The cost for steering rack service varies dramatically between DIY and professional repair, and depends heavily on whether you're doing a full rack replacement or just addressing components.

DIY Cost Example (Rack & Tie Rods):

• Remanufactured Steering Rack Assembly: $400 - $700
• Premium Greasable Outer Tie Rod Ends (Pair): $80 - $150
• Alignment (required post-install): $100 - $150
• Total DIY Cost Range: $580 - $1,000 This reflects the parts investment an owner would make. The labor is your own, which is significant. The quote about steering wheel reupholstery gives insight into the DIY labor value: "Just buy a new steering wheel or have it professionally upholstered. Would've gladly paid $1k to NOT do this myself." While for a different task, this shows owners place a high value on avoiding complex, frustrating DIY jobs—a rack replacement is several orders of magnitude more complex.

Professional Repair Cost Examples:

• Dealer/Shop (New OEM Rack): Parts: $1,200 - $1,800, Labor: 4-6 hours @ $150/hr = $600-$900. Total: $1,800 - $2,700+
• Independent Shop (Remanufactured Rack): Parts: $500 - $800, Labor: $600-$900. Total: $1,100 - $1,700
• Shop (Tie Rod Replacement Only - if rack is okay): Parts: $200-$400, Labor: 1.5-2 hours, plus alignment. Total: $450 - $700

These costs explain why many owners first investigate and replace the simpler, less expensive tie rod ends and ensure proper lubrication of joints before concluding the rack itself needs replacement.

Prevention

Preventing premature steering rack wear is centered on proactive maintenance of the entire steering linkage. The most effective strategy comes directly from owner wisdom: prioritize serviceable components. When any front-end part like tie rod ends or ball joints needs replacement, choose greasable versions. "Replace with greasable joints when possible and make sure you actually lube them and you'll see an increase in life span," is the golden rule. Regularly lubricating these fittings with a quality grease during oil changes or every other oil change flushes out contaminants and prevents dry wear that transmits shock to the rack.

Secondly, protect the rack itself. Periodically inspect the rubber bellows (boots) on each end of the steering rack for cracks, tears, or loose clamps. A torn boot allows road grit and water to enter, acting as an abrasive on the rack's internal seals and gears, leading to leaks and failure. Replacing a $20 boot is infinitely cheaper than a $700 rack. Finally, be mindful of impacts. Avoid hitting potholes and curbs at speed, and if you do go off-road, perform a visual inspection of the steering linkage afterward. Catching a slightly bent tie rod or a damaged boot early can save the rack.

FAQ

Q: How long does it take to replace a steering rack on a Tacoma? A: For a professional mechanic with a lift and all tools at hand, the book time is typically 4 to 5 hours. For a skilled DIYer working in a home garage, expect the job to take a full day, or potentially spread over a weekend, especially if you encounter rusty bolts or are doing it for the first time. This does not include the time needed for the mandatory wheel alignment afterward.

Q: Can I drive with a bad steering rack? A: It is not safe. Symptoms of a failing rack—such as excessive play, locking up, or complete loss of steering assist—can lead to a sudden and catastrophic loss of vehicle control. If you notice significant clunking, binding when turning, or major fluid leaks (on hydraulic systems), you should have the vehicle towed to a repair facility. Minor wear might manifest as slight looseness, but it should be inspected immediately.

Q: Is steering rack failure a common issue on the 2020 Tacoma? A: Based on owner discussions, the electric steering rack itself is not cited as a widespread, premature failure point. The more common issues revolve around wear in the connecting components (tie rod ends, ball joints) and general steering system maintenance. Failures are more often linked to high mileage, lack of lubrication, or damage from impacts rather than a inherent defect in the rack for this model year.

Q: DIY vs mechanic - what's recommended for a steering rack job? A: This is one of the more advanced repairs on a vehicle. You need confidence in working on critical safety systems, proper tools, and the ability to perform a preliminary alignment or get the truck to a shop without driving it far. The overwhelming advice, even for simpler interior jobs, leans professional for most people. As an owner said about a difficult DIY, "10/10 do not recommend this diy mod." For a steering rack, unless you are an experienced hobbyist with the right equipment, paying a professional is the recommended and safer course of action. The cost of a mistake here is extremely high.

Q: My steering feels like it's fighting me or correcting itself. Is that the rack? A: Probably not. The 2020 Tacoma is equipped with Toyota Safety Sense™, which includes Lane Departure Alert (LDA) with Steering Assist. This system can actively turn the steering wheel to guide you back into your lane if you drift without a signal. As one owner clarified, "That’s the active lane assist... it will automatically turn the wheel to correct it." This can feel unusual. Try turning off LDA via the button on the steering wheel to see if the sensation disappears before diagnosing a mechanical problem.

Q: Should I upgrade any parts when replacing the steering rack? A: Yes, it's an excellent opportunity. Consider installing upgraded, greasable outer tie rod ends. You can also install polyurethane steering rack mounting bushings. These bushings replace the soft rubber OEM ones and can reduce flex in the rack during steering input, providing a slightly more direct and responsive steering feel, which many owners pursuing mods appreciate.
