Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery (if working on electrical components).

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel covering the affected brake assembly using a lug wrench.
2. Use a socket set to remove the brake caliper bolts, then carefully lift the caliper off the rotor.
3. Inspect the brake pads for thickness; replace if worn below specifications (usually 3mm or less).
4. Check the rotor for scoring or warping; replace if necessary.
5. Reassemble the brake components, ensuring caliper bolts are torqued to manufacturer specifications (typically around 30 Nm).

3. Check and Replace Wheel Bearings

Sub-steps:
1. Remove the wheel and brake assembly as described previously.
2. Inspect the wheel hub for signs of damage or excessive play by shaking it up and down.
3. If faulty, remove the hub assembly, and replace the wheel bearing using a bearing puller and press, ensuring proper alignment.
4. Reassemble the hub and brake components, tightening to specified torque.

4. Inspect and Replace CV Joints

Sub-steps:
1. Raise the vehicle and support it securely on jack stands.
2. Remove the axle nut and detach the CV joint from the wheel hub.
3. Inspect the CV boots for cracks or grease leakage; replace if damaged.
4. If the joint is damaged, remove the axle shaft and replace the CV joint or entire axle assembly.
