Why Your Lifted Grand Cherokee Pulls (And How to Straighten It Out)

How to Fix Pulling

If your 2020 Jeep Grand Cherokee is pulling to one side, the solution often involves addressing the vehicle's alignment and suspension, particularly after modifications. This issue is frequently reported by owners who have changed tire sizes or installed a lift kit, which can alter the factory geometry and cause uneven tire wear or handling quirks. As one owner, Professional_Weird28, shared after modifying their SUV: "Was getting tired of the look of my 2020 limited x 4x4, so I got a 2.5inch lift and put on 33s." This type of change is a common precursor to pulling and requires specific corrections.

Symptoms

The primary symptom is a consistent tug or drift on the steering wheel, requiring you to apply constant pressure to keep the vehicle traveling straight. This is most noticeable on flat, level roads and can become more pronounced after installing larger tires or a suspension lift. The pull may feel like the truck is fighting you, leading to driver fatigue.

Owners often notice this symptom develop shortly after modifications. The change in tire diameter, weight, and suspension height directly impacts steering axis inclination and scrub radius. As one owner noted about their new, larger tires, the change in vehicle dynamics was significant enough to warrant mention, indicating that such upgrades don't come without potential handling trade-offs.

In some cases, the pulling may be accompanied by unusual tire wear patterns, such as feathering or cupping on the inside or outside edges of the tread. This is a telltale sign that the wheels are no longer aligned to the manufacturer's specifications. While not every owner reports checking their tread, those who experience persistent pulling should inspect their tires closely for these signs.

Most Likely Cause

The most likely cause of pulling on a modified 2020 Jeep Grand Cherokee is an incorrect wheel alignment following suspension or tire changes. When you install a lift kit or significantly larger tires, you change the vehicle's ride height and suspension geometry. The factory alignment specifications are designed for the stock configuration. A lift alters the angles of the control arms and steering linkage, while larger, heavier tires can place different stresses on the components. If the alignment is not professionally corrected to suit the new setup, the wheels will not be pointing straight ahead relative to the vehicle's centerline and the road, causing a persistent pull.

How to Diagnose

Diagnosing a pull requires a methodical approach to rule out simple causes before assuming an alignment issue. You will need a reliable tire pressure gauge and a flat, level stretch of road with minimal crown.

First, check all four tire pressures when the tires are cold. Incorrect pressure is the simplest cause of a pull, as an under-inflated tire has a different rolling radius and can drag. Ensure all tires are inflated to the placard on the driver's door jamb. Next, perform a visual inspection. Look for obvious signs of tire damage, bulges, or severe uneven wear. Swap the front tires from side to side. If the pulling direction changes or reverses, the issue is likely with the tires themselves (a condition known as tire pull). If the pull remains in the same direction after the swap, the problem is almost certainly in the suspension or alignment.

For a modified vehicle, the final and most critical diagnostic step is a professional alignment check. This requires taking the truck to a shop with a modern, computerized alignment rack. A skilled technician can measure the current camber, caster, and toe settings and compare them to both the stock specifications and the adjusted specifications recommended for your lift height. This will definitively identify which angles are out of spec and causing the pull.

Step-by-Step Fix

Fixing a pull caused by modification-related misalignment is a precise job. For most DIYers, the diagnosis is manageable, but the correction is best left to professionals with the right tools. However, if you have the equipment and confidence, here is the process.

1. Gather Specifications: Before starting, research the recommended alignment specifications for your specific lift kit height. Many lift kit manufacturers provide these. If not, you will need to find a shop experienced with lifted Jeeps.

2. Secure the Vehicle: Park on a perfectly level surface. Engage the parking brake and chock the rear wheels.

3. Initial Inspection: With the vehicle safely raised on jack stands, perform a thorough inspection of all front-end components. Check for worn tie rod ends, ball joints, and control arm bushings. Any worn part must be replaced before an alignment, as it will not hold the new settings. As one owner, 100naziscalpz, humorously noted about a different repair, be prepared for challenges: "Started at 11am 2 trips to harbor freight for tools, fighting the harness clips, dropping my only 10mm socket behind the engine..."

4. Loosen Adjustment Points: The primary adjustments for correcting a pull are the camber/caster bolts (often called eccentric bolts) at the lower control arms and the tie rod sleeves for toe. Spray these with penetrating oil if they are rusty.

5. Make Adjustments: This is the complex part. Using alignment gauges or a DIY alignment tool system, adjust the caster first. Increasing caster on the side the vehicle is pulling towards can help correct a drift. Then, adjust camber to be equal side-to-side and within spec. Finally, adjust toe-in to specification. This process requires patience and repeated measurement.

6. Road Test: After adjustments, lower the vehicle and take it for a test drive on your familiar, flat road. The pull should be significantly reduced or eliminated. Be aware that with very aggressive all-terrain tires, a slight "tracking" or following of road grooves is normal, but a firm pull is not.

7. Professional Verification: For peace of mind, it is highly recommended to take the vehicle for a final check on a professional alignment rack. They can fine-tune your settings for optimal tire wear and handling.

Parts and Tools Needed

• Parts: Depending on your inspection, you may need replacement front suspension components like tie rod ends or control arm bushings. If correcting alignment proves impossible, you may need aftermarket adjustable control arms or camber bolts designed for lifted applications.
• Tools:
  • Jack and jack stands
  • Basic socket and wrench set (including a 10mm socket—and maybe a magnet!)
  • Torque wrench
  • Tire pressure gauge
  • Penetrating oil (e.g., PB Blaster)
  • DIY alignment tool kit (e.g., toe plates, camber gauge) or access to a professional alignment rack.

Real Owner Costs

The cost to fix pulling varies dramatically based on whether you need just an alignment or additional parts.

• DIY Alignment Check/Simple Correction: If you only need to adjust tire pressure or perform a tire rotation, the cost is $0. If you purchase a basic DIY alignment tool set, expect to spend $100-$250. The real cost is your time, which can be several hours.
• Professional Alignment: A standard four-wheel alignment at a shop typically costs between $100 and $200. However, for a lifted vehicle, many specialty off-road shops charge more due to the additional time and expertise required—anywhere from $150 to $300.
• Alignment with Parts Replacement: This is where costs climb. If worn parts are discovered, you could be looking at parts and labor. For example, replacing both front tie rod ends and an alignment could cost $400-$600 at an independent shop. If adjustable control arms are needed to correct camber on a significant lift, parts alone can be $300-$600, with total costs exceeding $1,000.

As one owner investing in their vehicle's new look stated, modifications are a commitment: "V6 trailhawk, black tips and thrust mufflers coming next! And then I'm done until I need new tires 😭" — Numerous_Ad_1940. This highlights that the initial mod cost is often just the beginning.

Prevention

The best way to prevent pulling is to plan for a professional alignment immediately after installing any suspension lift or significantly larger tires. Do not drive the vehicle for more than a few miles to get to the alignment shop. When purchasing new tires, have them balanced and the alignment checked. Stick to high-quality tires known for even wear characteristics. As Ok_Zookeepergame8827 noted about their Falken Wildpeak A/T tires: "Don’t think I’ll ever buy a different tire." Choosing reputable brands can minimize the chance of a tire-induced pull. Finally, make checking tire pressure a monthly habit and inspect for uneven wear during rotations every 5,000-7,000 miles.

FAQ

Q: How long does it take to fix a pulling issue? A: If it's a simple tire pressure fix, just a few minutes. A professional alignment typically takes 1-2 hours at a shop. If you are doing a DIY suspension inspection and attempting your own alignment, set aside a full day, especially if you encounter rusty bolts or need to make multiple adjustments. As one owner's experience shows, even simple jobs can expand: "5 hours in I finally see the oil filter housing lol" — 100naziscalpz.

Q: Can I drive with my Jeep pulling to one side? A: You can drive it cautiously for short distances to a repair shop, but you should not ignore it. Continuous driving with a severe pull accelerates tire wear, can make the vehicle unstable in emergency maneuvers, and puts extra stress on steering and suspension components, leading to more expensive repairs.

Q: Is pulling a common issue on the 2020 Grand Cherokee? A: It is not a common inherent flaw with the stock vehicle. However, it is an extremely common consequence of modifying these popular SUVs. Owners who install lifts and larger tires frequently encounter alignment and handling changes that must be addressed, making it a frequent topic in owner communities.

Q: DIY vs mechanic - what's recommended for fixing a pull? A: For most owners, we recommend a hybrid approach. You can save money by doing the initial diagnosis yourself—checking tire pressure, inspecting for wear, and performing a tire rotation. However, the actual alignment correction, especially on a modified vehicle, is best left to a professional mechanic or a dedicated alignment shop. They have the precise equipment and expertise to get it right the first time, which will save you money on prematurely worn tires.

Q: Will new tires fix a pulling problem? A: Only if the tires themselves are the cause (a "tire pull"). If the pull is due to misalignment, new tires will temporarily mask the symptom until they too begin to wear unevenly. Always diagnose and correct the underlying alignment issue before purchasing new tires.

Q: My Jeep only pulls when I brake. Is that the same issue? A: No, that is a different problem. Pulling under braking is typically caused by a stuck caliper, a collapsed brake hose on one side, or contaminated brake pads. This requires a brake system inspection, not an alignment.
