Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Ensure the vehicle is securely lifted and supported before working underneath.

Symptoms

•Grinding noise when braking or while driving
•Vibration felt through the steering wheel or floor
•Decreased braking performance
•Unusual wear on brake pads or rotors
•Noise changes when turning left or right

Diagnostic Steps

1
Inspect brake components for wear or damage, including pads, rotors, and calipers.
2
Check wheel bearings for play or roughness by spinning the wheel and listening for noise.
3
Test drive the vehicle to replicate the noise and observe under different conditions (braking, turning).
4
Examine the drivetrain components, including the CV joints and axles, for any signs of damage.
5
Use a stethoscope or mechanic's tool to pinpoint the source of the noise while the vehicle is in motion.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery.

2. Brake Component Inspection and Replacement

Remove the Wheel
- Use a lug wrench to loosen and remove wheel lug nuts.
- Lift the vehicle using a jack and secure it with jack stands.
Inspect Brake Pads and Rotors
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor without hanging it from the brake line.
- Check the brake pads for thickness; replace if less than 3mm.
- Inspect the rotor for grooves or scoring; replace if damaged.
Replace Brake Pads and Rotors (if necessary)
- If replacing pads, compress the caliper piston using a C-clamp.
- Install new brake pads and reassemble the caliper over the rotor.
- Tighten caliper bolts to manufacturer specifications (typically around 20-30 ft-lbs).
- If replacing rotors, install the new rotor and secure it with the appropriate bolts or screws.

3. Wheel Bearing Inspection and Replacement

Check for Wheel Bearing Play
- Grab the wheel at 12 and 6 o'clock positions; check for any movement.
- If play is detected, proceed to replace the wheel bearing.
Remove Hub Assembly
- Remove the axle nut and disconnect the brake caliper assembly.
- Detach the wheel hub from the steering knuckle.
Replace Wheel Bearing
- Press out the old bearing using a bearing puller.
- Press in the new bearing and reassemble the hub assembly.
- Reinstall and torque all components to specifications.
