Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear wheels.
Disconnect the battery if working on electrical components.

2. Inspect and Replace CV Joints

Tools Required: Socket set, torque wrench, pry bar, CV joint puller.
Remove the wheel on the affected side to access the CV joint.
Inspect the CV boot for tears or grease leakage.
If damaged, use a CV joint puller to remove the old joint.
Install the new CV joint and ensure the boot is securely fastened. Torque to manufacturer specifications (usually between 30-50 lb-ft).

3. Check and Replace Suspension Components

Tools Required: Socket set, torque wrench, suspension tool kit.
Inspect control arms and bushings for wear.
If any bushings are cracked or excessively worn, remove the control arm using a socket set.
Replace with new components and torque to manufacturer specifications.

4. Inspect and Replace Wheel Bearings

Tools Required: Socket set, bearing puller, grease.
Remove the wheel and brake components to access the wheel hub.
Spin the wheel hub by hand to check for any roughness.
If rough, remove the hub assembly and replace the bearings.
Grease the new bearings and reassemble the hub, ensuring proper torque specifications are adhered to.

5. Check Steering Components

Tools Required: Socket set, torque wrench.
Inspect tie rod ends for any play by manually shaking them.
If loose, replace the tie rod ends and torque to manufacturer specifications.
