Solution

1. Preparation

Gather tools and parts needed for the repair.
Raise the front of the vehicle using a jack and secure it on jack stands.
Remove front wheels for better access to suspension components.

2. Inspect and Replace Damaged Components

Inspect Suspension:
- Check the control arms and bushings for wear. If any are damaged, proceed to replacement.
Replace Tie Rod Ends:
- Use a tie rod puller to remove the tie rod end from the steering knuckle.
- Install the new tie rod end and tighten it to the manufacturer’s specifications (typically around 35-45 ft-lbs).
Replace Ball Joints:
- Remove the lower control arm from the vehicle to access the ball joint.
- Use a ball joint separator tool to remove the old ball joint.
- Press in the new ball joint and secure it with the retaining clip.
Check and Replace Sway Bar Links:
- Remove the sway bar link from both the sway bar and lower control arm using a socket and wrench.
- Install the new sway bar links and torque to specifications (usually around 15-25 ft-lbs).

3. Reassemble and Lower Vehicle

Reinstall the front wheels and lower the vehicle from jack stands.
Ensure all fasteners are torqued to specification and perform a final visual inspection.
