Solution

1. Preparation

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

2. Inspect and Replace CV Joints

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, grease.
Lift the front of the vehicle and secure it on jack stands.
Remove the front wheels to access the CV joints.
Inspect the CV boots for tears or leaks.
If damaged, remove the CV joint by:
1. Unscrewing the axle nut using the socket set.
2. Using a pry bar to pop the CV joint from the hub.
3. Installing the new CV joint by reversing the removal steps and tightening the axle nut to manufacturer specifications (usually around 130-150 lb-ft).

3. Inspect and Replace Suspension Components

Tools Required: Socket set, torque wrench, ball joint separator.
Check for play in control arms, ball joints, and bushings:
1. If any components are worn, remove the affected part.
2. Replace with new parts, ensuring to torque all bolts to the manufacturer’s specifications.

4. Inspect and Replace Steering Rack or Tie Rod Ends

Tools Required: Socket set, torque wrench, steering wheel puller.
Check for looseness in the steering rack and tie rod ends:
1. If found to be faulty, remove the steering rack by disconnecting it from the steering column and the tie rod ends.
2. Replace with a new steering rack or tie rod end, ensuring to torque all bolts to specifications.
