Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Shocks/Struts

Lift the Vehicle: Use a jack to lift the vehicle and secure it with jack stands.
Remove Wheel: Use a socket set to remove the lug nuts and take off the wheel.
Inspect Shocks/Struts: Examine the shock absorbers or struts for any leaks, dents, or signs of wear.
Remove Shock/Strut:
- Remove the top retaining bolts using the socket set.
- Remove the bottom bolts securing the shock/strut to the control arm.
Install New Shock/Strut:
- Position the new shock/strut in place and secure it with the bolts.
- Torque the bolts to manufacturer specifications (consult service manual for exact torque values).
Reattach Wheel: Place the wheel back on and hand-tighten the lug nuts, then lower the vehicle and torque the lug nuts to proper specifications.

3. Inspect Control Arms and Bushings

Check for Wear: Look at the control arms and their bushings for any signs of cracking or damage.
Replace if Damaged: If any components are worn, remove the old control arm and replace it with a new one, securing it with the proper torque specifications.
