Solution

1. Preparation

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

2. Inspect and Replace Steering Components

Inspect Tie Rods and Ball Joints:
- Use a jack to lift the front of the vehicle and secure it with jack stands.
- Check for play in the tie rods and ball joints by moving them by hand.
- If worn, replace with new components using a socket set.
Replace Tie Rod Ends:
- Remove the cotter pin and castle nut from the tie rod end.
- Use a tie rod end puller to detach it from the steering knuckle.
- Install the new tie rod end, torque the castle nut to manufacturer specifications, and insert a new cotter pin.

3. Inspect and Replace Suspension Components

Check Struts and Bushings:
- Inspect the struts for leaks and check the bushings for cracks or wear.
- If damaged, remove the strut assembly using a socket set and replace it with a new strut. Torque bolts to specified values.
Replace Control Arm Bushings:
- Remove the control arms if bushings are worn.
- Press out the old bushings and install new ones, ensuring they are seated correctly.

4. Inspect and Replace CV Joints

Check CV Joints and Boots:
- Look for tears in the CV boot and listen for clicking noises while turning.
- If damaged, remove the axle assembly and replace the CV joint or entire axle as necessary.
