Solution

1. Preparation

Tools Required: Socket set, torque wrench, pry bar, jack stands, wheel chocks.
Safely park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Raise the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands to ensure stability.

3. Inspect and Replace Worn Components

a. Shock Absorbers/Struts

Remove the wheel to access the suspension.
Unbolt the top and bottom of the shock absorber or strut.
Replace with new components, ensuring proper alignment with mounting points.
Torque specifications: Refer to the manufacturer’s manual for specific torque values.

b. Control Arms and Bushings

If control arms or bushings show excessive wear, unbolt them using the socket set.
Replace with new control arms or bushings as needed.
Use a torque wrench to ensure all bolts are tightened to specification.

c. Sway Bar Links and Bushings

Inspect the sway bar links; if damaged, remove them using the socket set.
Install new sway bar links and bushings, ensuring proper alignment.
Torque to manufacturer specifications.

4. Reassemble and Lower Vehicle

Reattach the wheel and ensure all lug nuts are tightened to specification.
