Solution

1. Preparation

Gather tools and parts needed for the job.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Raise the vehicle using a jack and support it with jack stands.

2. Inspect and Replace Suspension Components

Inspect Control Arms and Bushings:
- Remove the wheel on the affected side using a lug wrench.
- Visually inspect control arms and bushings for cracks or excessive wear.
- If damaged, proceed to remove the control arm bolts using a socket set.
- Replace with new control arms/bushings and torque bolts to manufacturer specifications.
Check and Replace Struts (if necessary):
- If struts show signs of leaking or damage, detach them from the strut mounts and lower control arm.
- Replace with new struts and torque to specifications.

3. Inspect and Replace CV Joints

Inspect CV Joints:
- Check the CV joints and boots for cracks or grease leakage.
- If damaged, remove the axle nut using a socket and impact wrench.
- Disconnect the CV axle from the hub and the transmission.
- Install the new CV axle and torque the axle nut to manufacturer specifications.

4. Inspect and Replace Wheel Bearings

Check Wheel Bearings:
- Spin the hub to listen for grinding noises, indicating a bad bearing.
- If necessary, remove the hub assembly by taking out the wheel bearing bolts.
- Replace with new bearings and reassemble the hub, ensuring proper torque.
