Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery (if required for electrical components).

2. Lift 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 Components

A. Shock Absorbers/Struts

Remove the wheel to access the suspension.
Unscrew the bolts securing the shock absorber/strut to the lower control arm and upper mount.
Replace with new shock absorbers/struts, ensuring proper alignment of mounting points.
Torque bolts to manufacturer specifications (usually around 40-50 Nm).

B. Control Arm Bushings and Ball Joints

Remove the control arm from the vehicle by loosening the bolts securing it to the chassis and lower control arm.
Inspect the bushings and replace if cracked or worn.
If the ball joints are worn, replace them by pressing out the old joint and inserting a new one.
Reassemble the control arm and torque bolts to manufacturer specifications.

C. Sway Bar Links and Bushings

Disconnect the sway bar link from the sway bar and lower control arm.
Replace any worn bushings and sway bar links with new ones.
Ensure proper orientation and torque to specifications.

4. Reassemble and Lower the Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and torque the lug nuts to the manufacturer's specifications (usually around 100-120 Nm).
