1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery for safety if working on electrical components.

2. Inspect and Replace CV Joints

Inspect CV Joints:
- Raise the front of the vehicle using a jack and secure it with jack stands.
- Remove the front wheels using a socket set.
- Visually inspect the CV joints for any tears in the boots or excessive play.
Replace if Necessary:
- If damaged, remove the axle nut using a socket and breaker bar.
- Disconnect the lower control arm from the knuckle to free the CV joint.
- Slide out the CV axle from the transmission and replace it with a new one, ensuring proper seating.
- Reassemble the lower control arm and torque the axle nut to manufacturer specifications.

3. Inspect and Replace Wheel Bearings

Inspect Bearings:
- With the wheels off, check for play in the wheel hub by grasping it at the top and bottom and wiggling.
Replace if Necessary:
- If play is detected, remove the brake caliper and rotor.
- Remove the wheel hub assembly from the steering knuckle.
- Replace the bearing using a bearing press or suitable tool.
- Reassemble in reverse order, ensuring to torque all bolts to specifications.

4. Suspension Component Inspection

Inspect and Replace Components:
- Check struts, bushings, and other suspension parts for wear.
- Replace any worn parts using appropriate tools and torque settings as specified by the manufacturer.
