Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Raise the vehicle using a jack and secure it on jack stands.

Tools Required:

Jack and jack stands
Socket set
Torque wrench
Pry bar
Multimeter (if electronic components are involved)

2. Inspect and Replace Components

A. Inspect Struts and Shocks

Remove the wheels to gain access to the suspension.
Visually inspect struts for signs of oil leakage or physical damage.
If any strut is damaged, remove it by:
1. Unbolting the top mount and bottom bracket.
2. Disconnecting any sway bar links attached to the strut.
3. Installing new struts by reversing these steps, ensuring to torque bolts to manufacturer specifications.

B. Check Control Arms and Bushings

Inspect control arms for cracks or excessive wear on the bushings.
Replace any damaged control arms by:
1. Removing the bolts securing the control arm to the chassis and the knuckle.
2. Installing the new control arm and torquing to specifications.

C. Tighten Loose Fasteners

Check all suspension-related bolts for proper tightness.
Use a torque wrench to ensure all bolts are tightened to the specified torque values from the service manual.

3. Reassemble and Lower the Vehicle

Reinstall wheels and lower the vehicle.
Perform a final check to ensure all tools are removed from the workspace.
