Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat, level surface and engage the parking brake.
Disconnect the battery to prevent electrical issues during suspension work.

2. Inspect and Replace Damaged Suspension Components

Check Shock Absorbers/Struts:
- Remove the wheel using a socket set.
- Unbolt the shock absorber from the top mount and lower control arm.
- Inspect for leakage or damage; replace if necessary.
Replace Shocks/Struts:
- If replacement is needed, install a new shock or strut by securing it to the top mount and lower control arm.
- Torque bolts to manufacturer specifications (typically around 30-50 ft-lbs).

3. Alignment Adjustment

After replacing suspension components, perform a wheel alignment.
Use a wheel alignment machine to ensure all angles (caster, camber, toe) are within specifications.
Adjust as needed to achieve proper alignment.

4. Steering Component Inspection

Inspect tie rods and ball joints for wear.
If any components are worn, replace them:
- Remove the cotter pin and nut from the tie rod end.
- Use a tie rod puller to separate the tie rod end from the steering knuckle.
- Install the new tie rod end and secure it with a new nut, torquing it to manufacturer specifications.
