Solution

1. Preparation

Gather necessary tools and parts.
Ensure vehicle is parked on a flat surface and secure it with wheel chocks.
Lift the vehicle using a hydraulic jack and support it with jack stands.

2. Inspect and Replace Brake Components

a. Inspect Brake Pads and Rotors

Remove the wheel using a socket set.
Inspect brake pads for thickness; replace if below 3mm.
Check rotors for scoring or warping; replace if damaged.
Tools Required: Socket set, torque wrench, brake cleaner.

b. Replace Parts if Necessary

If pads are worn, remove the caliper bolts and slide the caliper off.
Replace the brake pads and reinstall the caliper.
Torque caliper bolts to manufacturer specifications.

3. Check and Replace Wheel Bearings

a. Inspect Wheel Bearings

Spin the wheel manually to check for roughness or excessive play.
If noise persists, remove the wheel hub assembly.

b. Replace Wheel Bearings

Remove the hub assembly and press out the old bearings.
Press in the new bearings and reassemble the hub.
Tools Required: Bearing puller, press, torque wrench.

4. Inspect and Repair Drivetrain Components

Check CV joints for cracks or tears in the boots.
Inspect axles for any signs of damage or wear.
Replace any damaged components as necessary.
Tools Required: Socket set, pry bar.
