Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Lift the front of the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace Suspension Components

Inspect Control Arms and Bushings:
- Check for cracks or excessive wear.
- If damaged, remove the bolts securing the control arm and replace it with a new one.
- Torque specifications: 80 ft-lbs for the control arm bolts.
Replace Worn Bushings:
- Use a bushing removal tool to extract old bushings.
- Install new bushings, ensuring they are seated properly.

3. Check and Replace Steering Linkage

Inspect the Tie Rod Ends:
- Look for play in the tie rods by moving the wheel back and forth.
- If damaged, remove the cotter pin and nut, then replace the tie rod end.
Adjust Steering Rack:
- Ensure that the steering rack is securely mounted and not loose.

4. Examine Drivetrain Components

Inspect CV Joints and Axles:
- Check for torn CV boots and any play in the joints.
- Replace any damaged CV joint assemblies.

5. Check Wheel Bearings

Test for Play:
- While the vehicle is lifted, grasp the wheel at 12 and 6 o'clock and check for movement.
- If there is play, replace the wheel bearing.
