Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and glasses.

2. Raise the Vehicle

Use a hydraulic jack to lift the vehicle and secure it on jack stands.
Ensure safety stands are positioned properly before working under the vehicle.

3. Inspect and Replace Components

Struts/Shocks Replacement:
1. Remove the wheel for access to suspension components.
2. Disconnect the strut from the lower control arm by removing the bolts using a socket set.
3. Detach the strut from the top mount inside the engine bay.
4. Replace the strut or shock absorber with a new unit, securing it in place with the original mounting hardware.
Sway Bar Links and Bushings:
1. Inspect sway bar links for play or damage. If necessary, remove the nuts using a wrench.
2. Remove the sway bar bushing clamps and replace with new bushings.
3. Reassemble and tighten all connections to manufacturer specifications.

4. Reassemble and Lower Vehicle

Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the manufacturer’s specified torque value.
