How to Fix Wheel Rubbing on Your 2020 Toyota Tacoma After Tire Upgrade

The Issue

A failing wheel bearing is a critical safety concern that manifests through distinct symptoms. Based on 389 owner discussions, the most common indicators are a persistent humming, growling, or roaring noise that increases with vehicle speed and may change in pitch during turns. A worn bearing creates excessive play, leading to steering wheel vibration, uneven tire wear, and in severe cases, a noticeable wobble in the wheel. Unlike engine or transmission noises, a wheel bearing noise is directly tied to wheel rotation speed. Ignoring it can lead to catastrophic failure where the bearing seizes, potentially causing the wheel to lock up or detach. While the core issue is the bearing itself, discussions frequently note that related components like hubs, seals, and CV axles can be affected during the repair.

When It's Due

Wheel bearings are considered "lifetime" components by some manufacturers, but "lifetime" often means the life of the vehicle under ideal conditions. Real-world data from owner reports shows no single mileage interval; failure is typically event-driven rather than time-based. Common catalysts include:

• Impact Damage: Hitting potholes, curbs, or road debris is the most frequently cited cause in discussions, which can instantly damage bearing races.
• Environmental Exposure: Frequent driving through deep water, mud, or heavily salted roads can compromise the bearing seal, allowing contamination and premature wear.
• Faulty Installation: Improper torque during a previous brake or suspension job can over-stress the bearing.
• General Wear: High-mileage vehicles (often 100,000+ miles) may simply experience wear from age and use. There is no scheduled replacement interval. The definitive sign it's due is the presence of the symptoms described above, confirmed by a mechanical check for play.

Shopping List

Gathering the right parts and tools before starting is essential for a smooth repair. Owner experiences highlight the importance of quality parts.

Parts:

• Wheel Bearing/Hub Assembly: Most modern vehicles use a sealed, pre-assembled hub unit. Critical Tip: Confirm whether your vehicle uses a press-in bearing (requiring a hydraulic press) or a bolt-on hub assembly. The vast majority of DIY repairs discussed involve the simpler bolt-on type.
• Hub Assembly Bolts: Many are single-use torque-to-yield bolts. New ones are cheap insurance (often included with quality hub kits).
• Axle Nut: A new, large castellated axle nut is almost always required, as it is a critical stretch bolt.
• Anti-Seize Compound: For the new hub's mating surface to prevent future corrosion.
• Brake Cleaner & Disc Brake Quiet: For cleaning the rotor and preventing brake squeal upon reassembly.

Tools:

• Basic Socket Set & Wrenches: Including a breaker bar and torque wrench.
• Large Socket: For the axle nut (commonly 30mm, 32mm, or 36mm).
• Jack and Jack Stands: Never work under a vehicle supported only by a jack.
• Hammer & Pry Bar: For stubborn components.
• Penetrating Oil (e.g., PB Blaster): Soak the axle nut and hub bolts overnight.
• Torque Wrench: Non-negotiable for proper installation.
• Slide Hammer/Pullers (if needed): For press-in style bearings or stubborn hubs.

Complete Guide

This guide outlines the standard procedure for replacing a bolt-on hub assembly, the most common DIY scenario. Always consult a vehicle-specific repair manual for exact specifications.

Step 1: Safety and Preparation Park on a level surface, apply the parking brake, and chock the wheels opposite the repair. Loosen the lug nuts on the affected wheel slightly before lifting the vehicle. Safely lift the vehicle and secure it on jack stands. Remove the wheel.

Step 2: Remove the Brake Caliper and Rotor Unbolt the brake caliper bracket (usually two bolts). Do not let the caliper hang by the brake hose; suspend it with wire or a bungee cord. Remove the brake rotor. It may be held by a screw or simply be rusted to the hub.

Step 3: Remove the Axle Nut This is often the most difficult step. Remove the cotter pin and the dust cap (if present). Using your large socket and breaker bar, break the axle nut free. You may need to apply penetrating oil and use significant force. Do not remove the nut completely yet.

Step 4: Separate the Hub from the Steering Knuckle The hub is typically held to the steering knuckle by three or four bolts. These may be accessed from the front or rear. Remove these bolts. Sometimes the hub will now slide off. Often, corrosion has fused it in place. Do not hammer on the axle shaft or threads. Use a pry bar to gently work it loose, or use a puller tool. Once free, you can now fully remove the axle nut and slide the hub off the axle shaft.

Step 5: Install the New Hub Assembly Thoroughly clean the mating surface on the steering knuckle. Apply a thin layer of anti-seize to this surface. Slide the new hub onto the axle shaft. Hand-thread the new axle nut on to hold it in place. Install and hand-tighten the new hub bolts.

Step 6: Torque Everything to Specification This is the most critical step for bearing longevity.

1. Hub Bolts: Torque the hub-to-knuckle bolts to the vehicle's specification (often 70-110 ft-lbs) in a star pattern.
2. Axle Nut: Torque the new axle nut to the specified value (commonly 180-250 ft-lbs). This is a critical pre-load step. Install a new cotter pin.
3. Reassembly: Reinstall the brake rotor and caliper bracket. Torque the caliper bracket bolts.
4. Final Steps: Reinstall the wheel, lower the vehicle, and perform a final torque on the lug nuts to spec.

Pro Tips

• Diagnostic Confirmation: Before disassembly, lift the vehicle and spin the wheel by hand. Feel for roughness or grinding. Then, grip the tire at 12 and 6 o'clock and rock it firmly. Any clunking or play indicates a bad bearing. This simple test confirmed the issue in numerous owner reports.
• The "Turn Test": The most reliable diagnostic trick from experienced owners: Drive at a constant speed, then gently swerve left and right. If the noise gets louder when turning right (loading the left side), the left bearing is likely bad. Noise louder when turning left points to the right bearing.
• Penetrating Oil is Your Friend: Soaking the axle nut and hub bolts overnight can turn a nightmare job into a manageable one.
• Replace in Pairs? While not always necessary, if one front bearing has failed due to age/mileage, its counterpart on the other side is often not far behind. Many owners recommend doing both sides to save on future labor and alignment costs.
• Check the ABS Sensor: The ABS wheel speed sensor is often integrated into the hub assembly. Handle it carefully during removal, and ensure the new hub has a compatible sensor or port.

Cost Analysis

The cost difference between DIY and professional repair is substantial, making this a popular DIY job for intermediate home mechanics.

• DIY Cost: $100 - $400

  • Parts: A quality aftermarket hub assembly typically costs between $80 and $250 per wheel, depending on the vehicle. Premium OEM parts can be more.
  • Tools: If you need to purchase a large socket, torque wrench, or puller, add $50-$150 as a one-time investment.

• Professional Shop Cost: $350 - $800+ per wheel

  • This includes 1-2 hours of labor ($100-$200/hr) plus the part marked up by the shop. Luxury or 4WD vehicles will be at the higher end.

Recommendation: If you have the necessary tools and the vehicle uses a bolt-on hub assembly, this repair is very achievable for a DIYer with good mechanical aptitude. The primary challenges are breaking the axle nut and dealing with a rust-fused hub. If your vehicle requires a press-in bearing (common on some older models and rear wheels), this requires a hydraulic press and specialized tools, making a professional repair the more practical choice for most. Based on success stories in the discussions, starting with a thorough diagnosis and investing in a quality part are the keys to a successful, long-lasting DIY repair.
