Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Use jack stands to lift the vehicle securely if necessary.

2. Inspect and Replace Suspension Components

Shock Absorbers/Struts:
1. Remove the wheel to access the suspension.
2. Detach the upper shock mount bolts using a socket set.
3. Remove the lower shock mount bolts and pull out the shock absorber.
4. Install the new shock absorber in reverse order, tightening bolts to manufacturer specifications (typically 30-40 ft-lbs).
Sway Bar Links:
1. Locate the sway bar and inspect links for damage.
2. Remove the nut at the top and bottom of the sway bar link using a wrench and socket.
3. Replace with new sway bar link and torque to specifications (usually around 15-20 ft-lbs).

3. Ball Joints and Tie Rods

Ball Joints:
1. Lift the vehicle and remove the wheel.
2. Use a ball joint separator to remove the ball joint from the control arm.
3. Replace the ball joint with a new one and secure it with the retaining clip and bolts as per specifications.
Tie Rods:
1. Loosen and remove the tie rod end nut.
2. Use a tie rod puller to detach it from the steering knuckle.
3. Replace with a new tie rod and adjust the alignment as necessary.
