Solution

1. Preparation

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

2. Inspect and Replace Suspension Components

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar.
Sub-steps:
1. Lift the vehicle using a jack and secure it on jack stands.
2. Remove the front wheel to access suspension components.
3. Use a pry bar to check for play in control arm bushings and ball joints. Replace any components showing excessive wear.
4. Remove the old control arm or bushings using the socket set. Install new parts and torque to manufacturer specifications (usually around 50-70 Nm).

3. Inspect and Replace CV Joints

Tools Required: Socket set, CV joint puller, grease.
Sub-steps:
1. If CV joints are suspected, remove the affected axle from the differential.
2. Inspect the CV boots for tears. Replace the CV joint assembly if the joint is damaged.
3. Install the new CV joint, ensuring it is properly lubricated, and reassemble the axle with the socket set, torquing to specifications.

4. Check and Replace Wheel Bearings

Tools Required: Bearing puller, socket set, grease.
Sub-steps:
1. Remove the brake caliper and rotor to access the wheel bearing.
2. Inspect the bearing for play; replace if damaged.
3. Use a bearing puller to remove the old bearing and press in a new one, ensuring it is adequately greased.
