Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the vehicle.

2. Inspect and Replace CV Joints (if necessary)

Tools Required: Socket set, torque wrench, pry bar, CV joint puller.
Remove the wheel on the affected side using a socket set.
Use a pry bar to disconnect the lower control arm from the steering knuckle, if necessary.
Remove the axle nut and slide the CV axle out of the hub.
Inspect the CV joint for wear; if the boot is torn or the joint is damaged, replace the CV axle.
Reinstall the new CV axle and torque the axle nut to the manufacturer’s specifications (typically around 30-50 lb-ft).
Reassemble the lower control arm and wheel.

3. Inspect and Replace Suspension Components (if necessary)

Tools Required: Socket set, torque wrench, ball joint separator.
If any bushings or ball joints are found to be worn, remove the affected component.
Replace worn bushings with new ones, ensuring to lubricate them as per manufacturer specifications.
Install new ball joints if required, ensuring they are torqued to the proper specifications.
Reassemble all components and ensure everything is tightened properly.
