Solution

1. Preparation

Gather all tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues during repair.

2. Inspect and Replace CV Joints

Raise the Vehicle: Use a jack and jack stands to elevate the front of the car securely.
Remove Wheel: Use a socket set to remove the lug nuts and take off the front wheel.
Inspect CV Joint: Check the CV joint for any signs of damage or leaking grease.
Remove CV Joint: If damaged, detach the CV joint from the axle using a socket set and hammer if necessary.
Install New CV Joint: Apply grease to the new CV joint and connect it to the axle, tightening to the manufacturer's specified torque (typically 30-50 lb-ft).
Reinstall Wheel: Place the wheel back on, tighten lug nuts to the specified torque (usually 80-100 lb-ft).

3. Inspect and Replace Suspension Components (if needed)

Examine Suspension Parts: Check for any worn-out bushings, control arms, or strut mounts.
Remove Affected Components: If any parts are worn, use the appropriate tools to remove them (socket set, wrenches).
Install New Parts: Replace with OEM or high-quality aftermarket components, ensuring all bolts are torqued to specifications.
Reassemble Suspension: Reattach any removed components, making sure to follow the correct assembly sequence.
