Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and securely lifted with jack stands.
Disconnect the battery if required for electrical components.

2. Inspect and Replace CV Joints

Tools Required: Socket set, pry bar, CV joint puller, grease, torque wrench
Remove the wheel and tire from the affected side.
Inspect the CV boot for tears or damage. If damaged, proceed to replace:
1. Remove the axle nut using a socket and ratchet.
2. Use a CV joint puller to detach the axle from the hub.
3. Remove the old CV joint and clean the axle shaft.
4. Install the new CV joint, ensuring proper alignment.
5. Reassemble by securing the axle nut to the manufacturer’s torque specifications (usually around 150 ft-lbs).

3. Inspect and Replace Wheel Bearings

Tools Required: Bearing puller, socket set, torque wrench
After removing the wheel, check for play in the hub:
1. If play is detected, remove the brake caliper and rotor.
2. Use a bearing puller to remove the wheel hub and bearing assembly.
3. Replace with new bearings and reassemble in reverse order, applying proper torque.

4. Inspect Suspension Components

Tools Required: Wrench set, inspection mirror
Check for any loose or damaged suspension components:
1. Inspect control arms, bushings, and struts for wear.
2. If any components are worn, remove and replace as necessary.
3. Torque all bolts to manufacturer specifications.
