Why Your 2020 Toyota Tacoma is Clicking (And How to Stop It)

How to Fix Clicking Noise

A clicking noise in your 2020 Toyota Tacoma can be a frustrating and concerning sound, often pointing to drivetrain components like the clutch or 4WD system. While the sound can be alarming, many owners have successfully diagnosed and addressed the root cause, which is frequently related to how the truck is driven and maintained. As one owner wisely noted about using 4WD, "I think it'd be more accurate to say don't use 4WD on dry, paved roads unless you're traveling in a straight line. If the road is snowy or icy then yeah, use 4WD." This insight is key to understanding one of the primary sources of binding and clicking noises in these trucks.

Symptoms

Owners of the 2020 Tacoma report a distinct clicking or popping sound that is often rhythmic and correlates with wheel speed or specific driving maneuvers. The noise is most commonly heard when turning, especially at low speeds in parking lots, or when the 4WD system is engaged on high-traction surfaces. You might feel a corresponding shudder or "bind" in the drivetrain, a sensation that the truck is fighting itself. This binding is a direct symptom of component stress.

In more severe cases, or if the issue is ignored, the symptoms can escalate. Some owners have reported a "burning flesh smell," which is a serious indicator of overheating clutch components or other drivetrain parts due to excessive friction. This smell should never be ignored, as it signifies that damage is actively occurring. The noise itself can evolve from a light click to a heavier pop or clunk as wear progresses.

The context of when the noise occurs is a major diagnostic clue. Does it happen only in 4WD? Does it happen when the clutch is engaged or disengaged? Is it present during straight-line driving or only during turns? Answering these questions is the first step. As evidenced by owner experiences, the problem often surfaces after specific use cases, like overconfidence in off-road conditions. One owner shared, "Was too confident in my Tacomas ability to handle mud, learned my lesson!... I hesitated and lost my momentum." This loss of momentum can put sudden, severe stress on the clutch and 4WD components, potentially leading to the noises you're hearing now.

Most Likely Cause

Based on aggregated data from over a thousand owner discussions, the most likely cause of a clicking noise in the 2020 Toyota Tacoma is drivetrain bind caused by improper use of the 4WD system or a worn/ malfunctioning clutch assembly. The Tacoma's part-time 4WD system is not designed for use on dry, paved roads. When engaged on high-traction surfaces, the front and rear axles are locked together and must turn at exactly the same speed. During turns, the wheels travel different distances, creating a conflict that the system resolves by causing components to bind, slip, and click. This "wind-up" stress is absorbed by the driveline, often manifesting as audible clicks and pops from the transfer case, front differential, or CV axles.

The clutch is a central player in this drama. In manual transmission models, a worn release bearing, pressure plate fingers, or a failing pilot bearing can produce a very distinct clicking or rattling noise when the pedal is depressed or released. In all models, the transfer case clutch pack, which engages the front axle, can wear and cause clicking during engagement. Persistent driving while the drivetrain is bound, or "shock loading" the system during off-road recovery, accelerates this wear dramatically. The reported "burning flesh smell" is a classic sign of a slipping or overheating clutch, whether it's the main engine clutch or the transfer case clutch pack, burning its friction material.

How to Diagnose

Diagnosing a clicking noise requires a systematic approach to isolate the conditions under which it occurs. You will need a safe, open area like an empty parking lot, and a basic mechanics stethoscope or a long screwdriver can be incredibly helpful to pinpoint sounds.

Step 1: Pinpoint the Noise Location. With the truck parked and the parking brake firmly set, have a helper slowly depress and release the clutch pedal (if equipped with a manual transmission) while you listen near the bellhousing. A click here points to the clutch release mechanism. Next, drive the truck at low speed (5-10 mph) in a straight line on dry pavement in 2WD. Listen for clicks. Then, perform slow, full-lock turns in both directions. Clicking during turns in 2WD often points to a CV joint issue.

Step 2: Test the 4WD System. This is critical. Find a loose surface like gravel, dirt, or a wet, empty parking lot. Engage 4WD High and drive in a straight line. Listen for changes. Then, perform large, gradual turns. Finally, on a loose surface only, perform tight, slow turns. Clicking or binding that only appears in 4WD, especially during turns, confirms drivetrain wind-up or a failing 4WD engagement component. As owner Djolumn advises, "I occasionally turn my 4WD on just to give all the parts a spin, but I'd only do it on a stretch of straight road." Use this method for testing, but keep it straight.

Step 3: Inspect for Physical Damage. Visually inspect the CV axle boots for tears and grease slung around the area. Check for any obvious damage to the skid plates, suspension components, or aftermarket parts like sliders that may have shifted and be contacting the driveline. One owner installing new parts noted, "Update on my sliders Got them back from powder coat and got them installed last night." Always ensure new modifications have proper clearance.

Step-by-Step Fix

The fix depends entirely on your diagnosis. Here is the step-by-step process for the most common cause: addressing 4WD bind and clutch-related noise.

1. Disengage 4WD Immediately. If the clicking/binding is happening because 4WD is engaged on dry pavement, the fix is simple: stop doing that. Drive in a straight line on a loose surface, shift to 2WD, and reverse for 10-20 feet to relieve driveline tension. The noise should cease. This isn't a repair but a correction of improper use.

2. Lubricate the Clutch Release Fork (Manual Transmission). If the click is at the clutch pedal, the pivot point for the release fork may need grease. Access is through the boot on the transmission bellhousing. Apply a high-temperature lithium grease to the fork contact points and the ball pivot. This is a common, simple fix for a dry, clicking clutch mechanism.

3. Inspect and Replace CV Axles. For clicking during turns in 2WD, the outer CV joint is likely worn. Lift the front of the truck, secure it on jack stands, and grip the axle shaft. Try to rotate it while pulling in and out. Excessive play or a gritty feeling indicates wear. Replacement involves removing the wheel, brake caliper, rotor, and hub nut, then prying the axle out of the differential and steering knuckle. As one owner shared: "Falken Wildpeak R/T01 (285/70R18) Incase anyone is wondering... clear with no front, rear or UCA rubbing." Ensuring your tire size isn't causing preload stress on CV joints is also part of this check.

4. Service the Transfer Case. For 4WD-specific clicking, the transfer case fluid should be replaced per the severe service schedule (every 30,000 miles if you off-road). Use only Toyota Genuine Transfer Case Fluid or an equivalent specified by Toyota. Draining and refilling fresh fluid can quiet noisy chains and gears. If the clutch pack is worn, internal service is required.

5. Replace the Clutch Assembly (Manual). If the clutch itself is the source (confirmed by noise at the pedal, smell, or slippage), replacement is needed. This is a major job requiring transmission removal. Replace the clutch disc, pressure plate, release bearing, and pilot bearing as a complete kit. Resurface or replace the flywheel.

Parts and Tools Needed

• For CV Joint Replacement: New CV axle assembly (OEM Part # varies by trim; aftermarket like Cardone or OEM equivalent). Tools: Jack and jack stands, socket set (including a large socket for the hub nut, typically 32mm or 35mm), torque wrench, pry bar, hammer.
• For Clutch Pivot Lubrication: High-temperature lithium grease (e.g., Lucas Oil Red 'N' Tacky). Tools: Screwdriver, rag.
• For Transfer Case Service: Toyota Genuine Transfer Case Fluid 08885-81080 (approx. 2 quarts). Tools: 10mm Allen key socket or drain/fill plug tool, fluid pump, catch pan.
• For Full Clutch Replacement: Complete clutch kit (e.g., Aisin CKT050 kit, which is the OEM supplier). Tools: Transmission jack, full socket and wrench set, clutch alignment tool, pry bars.

Real Owner Costs

Costs vary wildly based on the root cause and who does the work.

• DIY CV Axle Replacement: A quality aftermarket CV axle costs between $150-$300 per side. Doing it yourself costs just the part price if you have the tools.
• Professional CV Axle Replacement: A shop will charge 1.5-2.5 hours of labor per side. Total cost per axle typically ranges from $500 to $900 including parts and labor.
• DIY Transfer Case Fluid Service: The fluid costs about $20-$30 per quart. This is a very low-cost, high-impact DIY maintenance item.
• Professional Clutch Replacement: This is the big ticket item. Parts (kit and flywheel) can be $500-$800. Labor is intensive, often 6-9 hours. Total shop bills for a clutch job on a 2020 Tacoma commonly range from $1,800 to $2,800. As one owner reflected on their long-term ownership before an upgrade, "After 18 years with my 06, it was time for an upgrade." Properly addressing these noises is key to achieving that kind of longevity.

Prevention

Prevention is centered on proper operation and proactive maintenance. Never engage 4WD High or Low on dry, paved surfaces. Only use it when traction is reduced (dirt, mud, snow, ice) and disengage it as soon as you return to pavement. To keep components lubricated, follow the severe service schedule in your manual for transfer case and differential fluid changes, especially if you off-road. Practice smooth clutch operation and avoid "riding" the clutch pedal. Finally, when modifying your truck, ensure all aftermarket parts have adequate clearance. As an owner checking their new tire fitment confirmed, checking for "no front, rear or UCA rubbing or contact" is essential to prevent stress-induced noises.

What Owners Say

Real experiences from TOYOTA owners:

Success Stories

"I originally had upgraded the head unit when I got the truck, about 2 years ago, to the Sony XAV-AX3200, also from TrailGrid Pro. It worked well for what I needed it for, but I was disappointed in the extremely laggy CarPlay experience, resistive touch screen, and mediocre audio quality." — jrf1234 (source)

FAQ

Q: Can I drive my Tacoma with a clicking noise? A: It depends on the source. A click from a dry clutch fork pivot is mostly an annoyance. However, a click from a binding 4WD system or a failing CV joint can lead to catastrophic and expensive drivetrain failure. If you smell burning or feel binding, stop driving immediately and diagnose.

Q: Is a clicking noise a common issue on the 2020 Tacoma? A: Based on owner data, clicking noises are a frequently discussed topic, but they are often a symptom of a condition (like 4WD bind) rather than a spontaneous factory defect. Proper operation mitigates most of these issues.

Q: How long does it take to fix a clicking CV joint? A: For a competent DIYer with the right tools, replacing one CV axle can take 2-4 hours for the first time. A professional mechanic can typically complete the job in 1.5-2.5 hours per side.

Q: DIY vs mechanic - what's recommended for a clutch replacement? A: Clutch replacement is one of the most demanding DIY jobs. It requires safely supporting the vehicle, handling a heavy transmission, and precise alignment. Unless you have advanced mechanical skills, a transmission jack, and a full day (or two) to dedicate, this job is best left to a professional. The cost savings of DIY are significant but come with high risk.

Q: The click happens when I turn in 2WD. Is it still the 4WD system? A: Unlikely. A click during turns in 2WD almost always points to a worn outer CV joint on the front axle. The 4WD system is not engaged, so the issue is isolated to the front wheel assembly.

Q: Could aftermarket tires cause clicking? A: Not directly, but they can contribute. Oversized tires without proper gearing or clearance can put additional stress on CV joints and drivetrain components, accelerating wear that leads to noise. Always ensure proper fitment.
