Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to ensure safety while working.

2. Inspect and Replace CV Joints

Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Remove the wheel by loosening the lug nuts with a socket and ratchet.
3. Inspect the CV joint boots for tears or grease leaks; if damaged, proceed to replace.
4. Use a 12mm socket to remove the bolts securing the CV joint to the wheel hub.
5. Slide the CV joint off the axle shaft.
6. Install the new CV joint by sliding it onto the axle shaft and securing it with bolts.
7. Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications (usually around 100 Nm).

3. Inspect and Replace Wheel Bearings

Sub-steps:
1. Remove the wheel again to access the hub assembly.
2. Use a bearing puller to extract the old wheel bearing from the hub assembly.
3. Clean the hub area thoroughly and install the new wheel bearing.
4. Press the new bearing into place using a bearing press or appropriate tool.
5. Reassemble the wheel assembly and torque the lug nuts to specifications.

4. Inspect Suspension Components

Sub-steps:
1. Examine the control arms, bushings, and struts for any signs of wear or damage.
2. Replace any worn bushings using a bushing tool or press.
3. Tighten all bolts to the manufacturer’s specified torque values.
