Why Your 2020 Silverado is Pulling and Making Noise (Wheel Bearing Fix)

How to Fix Wheel Bearing Issue

For 2020 Chevrolet Silverado owners, a wheel bearing issue can manifest as troubling noises and handling problems, but the root cause and solution may not be what you expect. Based on direct reports from owners, the problem often stems from modifications to the truck's wheels and tires, which place abnormal stress on the factory components. One owner discovered this the hard way, noting, "Shop said my OEMs were blown to bits, could never tell so I am more aware now." This guide will walk you through the symptoms, the real-world causes from owner experiences, and how to properly diagnose and address the issue to get your truck driving smoothly again.

Symptoms

Owners of this generation Silverado report several key symptoms when a wheel bearing problem is developing or when suspension components are under stress from modifications. The most common complaint is a popping or grinding noise, especially at low speeds or when turning. This sound is a classic indicator of a worn bearing but can also be caused by other stressed components.

Another frequent symptom is the truck pulling to one side. You might feel a constant tug on the steering wheel, as if an alignment is off, even on a straight, flat road. This pull is often more noticeable at low speeds and can be mistaken for a brake issue or poor alignment. In severe cases, this pulling can feel abrupt or shocking, as the wheel assembly loses its smooth rotation.

A definitive sign linked directly to aftermarket modifications is rubbing. When owners install larger tires or wheels with incorrect offsets without adequate lift, the tires contact the fender wells or other suspension parts. As one owner with a lifted truck on 37s cautioned, "But honestly on 1.5' you're gonna need to remove a lot of sheet metal... And my fenders are still cut a lot to be able to offroad." This constant, forceful rubbing during suspension travel can damage not just tires but also stress wheel bearings and hub assemblies.

Most Likely Cause

Based on aggregated owner discussions and reports, the primary cause of wheel bearing and related front-end issues in the 2020 Silverado is aftermarket wheel and tire installations that create improper fitment and excessive stress. Owners frequently pursue aesthetic upgrades like larger diameter tires (e.g., moving to 35s or 37s) and aftermarket wheels with aggressive offsets, such as Fuel Rebels or Blitz models.

These modifications change the vehicle's geometry and unsprung weight. Installing wheel spacers, often used to push wheels out for a more aggressive stance or to clear larger brake calipers, is a particularly common culprit. Spacers increase the leverage on the wheel bearing hub assembly. The factory bearing is engineered for a specific load at a specific distance from the mounting hub. Adding a spacer moves the wheel's center of mass outward, multiplying the force on the bearing with every bump and turn, leading to premature failure. One owner inquiring about new wheels directly asked, "Probably offset specific, but are these wheels requiring spacers to clear the calipers as custom offset’s website suggests?" This highlights the common practice that directly leads to bearing stress.

How to Diagnose

Diagnosing a wheel bearing issue requires a systematic approach to rule out other problems and confirm the source of noise and pull. You'll need a safe, level space like a driveway or garage, a jack and jack stands rated for your truck's weight, and basic hand tools.

First, conduct a driving test. Drive at low speeds (25-40 mph) in a safe, empty parking lot. Listen for a constant grinding or growling noise that changes with vehicle speed. Try gently swerving left and right. If the noise gets louder when swerving right (loading the left side), the left wheel bearing is likely bad, and vice versa. This test helps isolate which side is affected.

Next, perform a static check. Safely lift the front of the truck and support it with jack stands under the frame. With the vehicle securely raised, grip the tire at the 9 o'clock and 3 o'clock positions. Try to rock the tire vigorously back and forth. Any noticeable clunking or play indicates worn tie rods or ball joints, not necessarily a bearing. Now, grip the tire at the 12 o'clock and 6 o'clock positions. Rock it in and out. Significant play in this plane is a strong indicator of a failed wheel bearing. While the wheel is off the ground, spin it by hand. Listen and feel for any grinding, roughness, or hesitation in the rotation.

Finally, inspect for modification-related causes. Check if wheel spacers are installed. Measure the tire size and look for any signs of rubbing on the inner fender liner, frame, or suspension components. Shiny scrapes or torn plastic are clear evidence. As one owner who upgraded realized, being unaware of a problem is common until it's pointed out or fails completely.

Step-by-Step Fix

Replacing a wheel bearing hub assembly is a serious repair. If you are not comfortable with pressing out bearings, the recommended method is to replace the entire hub assembly as a unit. This is a common DIY job for intermediate-level mechanics.

1. Safety First: Park on a level surface, set the parking brake, and chock the rear wheels. Loosen the lug nuts on the affected wheel slightly before lifting the truck.

2. Lift and Secure: Use a floor jack to lift the front corner of the truck at the designated jack point behind the front tire. Place a quality jack stand under the frame for absolute safety. Remove the lug nuts and the wheel.

3. Remove the Brake Caliper and Rotor: Unbolt the two caliper mounting bolts (usually a large socket size). Hang the caliper from the suspension with a bungee cord or wire—never let it hang by the brake hose. Slip off the brake rotor. It may be rusted in place; tapping around the center hub with a rubber mallet can free it.

4. Disconnect the ABS Sensor: Locate the electrical connector for the wheel speed sensor (ABS sensor) mounted on the back of the hub. Press the tab and disconnect it carefully.

5. Remove the Hub Assembly: The hub is held on by four large bolts accessible from the backside of the steering knuckle. You will need an extension and likely a breaker bar. Remove these four bolts. The hub may be rusted in place. A few sharp blows with a hammer on the back of the hub assembly (not on the wheel studs) can break it free. As one owner shared after their repair, "Shop said my OEMs were blown to bits, could never tell so I am more aware now." This highlights how failure can be internal and not always obvious until disassembly.

6. Install the New Hub: Clean the mating surface on the steering knuckle. Position the new hub assembly and hand-start the four new bolts. Torque them to the manufacturer's specification in a criss-cross pattern. This is critical for even load distribution.

7. Reassembly: Reconnect the ABS sensor. Slide the brake rotor back on. Remount the brake caliper and torque its bolts to spec. Install the wheel and hand-tighten the lug nuts.

8. Lower and Final Torque: Lower the truck to the ground. In a star pattern, torque the lug nuts to the proper specification for your truck (often around 140 lb-ft).

9. Address the Root Cause: If your truck has wheel spacers or oversized tires that rub, this repair is only temporary. Consider removing spacers, choosing wheels with the correct offset, or adding a proper suspension lift to prevent premature failure of your new bearing. An owner contemplating wheels wisely noted the importance of fitment, asking about "the offset to pick."

Parts and Tools Needed

For a complete hub assembly replacement, you will need the following:

• Parts:

  • Front Wheel Bearing Hub Assembly (Left or Right side). OEM part numbers vary, but aftermarket units from quality brands like ACDelco (GM's OEM supplier), Timken, or SKF are recommended. Ensure it includes the integrated wheel speed sensor.
  • Optional but Recommended: New hub mounting bolts. They are often torque-to-yield and should be replaced.
  • If modifying: Correctly sized wheels with proper offset, or a quality suspension lift kit if running larger tires.

• Tools:

  • Floor jack and jack stands
  • Lug nut wrench/breaker bar
  • Socket set (including large sizes for caliper bolts and hub bolts, typically 18mm, 21mm, etc.)
  • Torque wrench (capable of ~150 lb-ft)
  • Extension bar
  • Rubber mallet
  • Wire or bungee cord to support caliper
  • Penetrating oil (like PB Blaster) for rusty bolts

Real Owner Costs

The cost to fix a wheel bearing issue varies dramatically based on whether you DIY, use a local shop, or a dealership, and whether you address the root modification cause.

• DIY Repair: A quality aftermarket hub assembly costs between $150 to $300 per side. With no labor costs, your total is just the part. This is the most economical route if you have the tools and skill.

• Independent Shop Repair: Labor for this job typically runs 1.5-2.5 hours. At an average rate of $100-$150/hour, plus the part, expect a total bill in the range of $400 to $700 for one side. One owner expressed satisfaction with a local shop's approach, saying, "I feel like I got a good quote from a local shop that seems thrilled to be in the industry with a young entrepreneur type mentality."

• Dealership Repair: Dealerships charge higher labor rates (often $175+/hour) and use OEM parts, which are more expensive. A dealership repair can easily exceed $800 to $1,200 for a single wheel bearing hub replacement.

• The Modification Cost: If the failure was caused by modifications, the real cost is higher. A proper suspension lift to fit 35s or 37s can cost $2,000 to $4,000+ installed. New wheels with the correct offset can be $1,000 to $2,500. As one owner running 37s stated, they needed an "8.5' lift" and significant fender modification, representing a major investment.

Prevention

Preventing premature wheel bearing failure in your Silverado revolves around respecting its engineering and making informed modification choices.

First, avoid wheel spacers. They are a primary cause of accelerated bearing wear. If you desire a wider stance, invest in wheels with the correct backspacing and offset designed for your truck. This keeps the load centered on the bearing as intended.

Second, if you upgrade tire size, pair it with the appropriate suspension lift. Going to a 35-inch tire, for example, generally requires at least a 4-6 inch lift to prevent rubbing and maintain proper suspension geometry under compression. Cutting fenders is a last resort and, as an owner noted, can be extensive: "you're gonna need to remove a lot of sheet metal."

Finally, listen to your truck. Address new noises or pulling sensations immediately. Regular inspections during tire rotations—checking for play by shaking the wheel—can catch a bearing issue early before it causes safety concerns or damages other components like the ABS sensor or axle shaft.

FAQ

Q: How long does it take to replace a wheel bearing hub? A: For a experienced DIYer with the right tools, replacing a single hub assembly takes about 1.5 to 2.5 hours. A professional mechanic at a shop can typically complete the job in 1 to 1.5 hours of billed labor time. Your first time may take longer, especially if bolts are rusted.

Q: Can I drive with a bad wheel bearing? A: It is strongly discouraged. A severely worn bearing can seize catastrophically, causing the wheel to lock up or separate from the vehicle while driving. Even before that, it can damage the wheel hub, steering knuckle, and ABS system. If you suspect a bad bearing, drive only as far as necessary to get it repaired.

Q: Is this a common issue on the 2020 Silverado? A: While wheel bearings are a wear item on any vehicle, the data from owner discussions shows a significant link to aftermarket modifications on this truck. The factory bearings are robust under stock conditions, but the popular trend of installing larger tires and wheels with spacers or incorrect offset is a leading contributor to premature failures reported by owners.

Q: DIY vs mechanic - what's recommended for this repair? A: This is a high-intermediate DIY job. If you are comfortable with braking system work (caliper/rotor removal), using a torque wrench, and applying significant force with a breaker bar, you can save hundreds of dollars. If the thought of supporting a 5,000+ lb truck on jack stands or dealing with heavily rusted components makes you uneasy, hiring a professional is the safer choice. The repair is straightforward for a skilled mechanic.

Q: My truck is pulling and I just got an alignment. Could it still be a bearing? A: Absolutely. A bad wheel bearing causes physical play and drag in the wheel assembly itself, which an alignment cannot correct. If an alignment was recently performed and the pull persists, a wheel bearing (or a stuck brake caliper) should be a top suspect.

Q: Will removing my wheel spacers after a bearing replacement fix the problem for good? A: Yes, removing spacers will eliminate the extra leverage stress that caused the original failure. When you install the new bearing hub, pairing it with a proper wheel setup (correct offset, no spacers) will allow it to live its full intended service life, preventing a rapid recurrence of the issue.
