Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the rear wheel using a socket set.
2. Take off the brake caliper by removing the caliper bolts. Use a torque wrench to ensure proper reinstallation.
3. Inspect brake pads for wear; replace if less than 3mm thick. Replace rotors if they are scored or below the minimum thickness specifications.
4. Clean the caliper and rotor surfaces with brake cleaner.
5. Reinstall the brake caliper and wheel, ensuring all bolts are torqued to manufacturer specifications.

3. Inspect and Replace Wheel Bearings

Sub-steps:
1. If the wheel bearings are found to be faulty, remove the rear wheel and brake assembly as described above.
2. Use a bearing puller to remove the old wheel bearing from the hub.
3. Clean the hub assembly and apply grease to the new bearing before installation.
4. Carefully press the new bearing into place using a hydraulic press or appropriate tools.
5. Reassemble the brake components and wheel, ensuring proper torque specifications are followed.

4. Inspect Suspension Components

Sub-steps:
1. Visually inspect the rear suspension for any damaged or worn components such as bushings, shocks, or struts.
2. Replace any worn or damaged suspension parts as necessary.
3. Ensure all bolts are tightened to the specified torque settings.
