Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and securely raise it using a jack and jack stands.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Suspension Bushings

Tools Required: Socket set, torque wrench, pry bar, lubricant.
Remove the wheel on the affected side to access the suspension.
Inspect the bushings visually for cracks or wear.
If damaged, use a pry bar to carefully remove the old bushings from the control arms or sway bar links.
Apply lubricant to the new bushings before installing.
Install the new bushings and torque to manufacturer specifications (usually around 40-50 Nm, but refer to the service manual for exact values).

3. Inspect and Replace Sway Bar Links

Tools Required: Socket set, torque wrench.
With the wheel removed, locate the sway bar links.
Check for any play or damage in the sway bar links.
If necessary, remove the sway bar link by unbolting it from the sway bar and the control arm.
Install the new sway bar link and torque the bolts to the manufacturer specifications.

4. Inspect Shock Absorbers

Tools Required: Socket set, multimeter (if electronic dampers are present).
Check the shock absorbers for leaks or physical damage.
Perform a bounce test: Push down on the corner of the vehicle and observe if it bounces back without excessive movement.
If the shock absorbers are faulty, remove them by unbolting from the top and bottom mounts.
Install new shock absorbers and torque the bolts according to specifications.
