Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues while working on the suspension.

2. Inspect and Remove Damaged Components

Tools Required: Socket set, wrench set, jack stands, floor jack.
Inspect the shock absorbers and struts for leaks or damage.
If defective, use a floor jack to lift the vehicle and secure it with jack stands.
Remove the wheel to access the suspension components.
Disconnect any electrical connectors if equipped with electronic dampers.

3. Replace Shock Absorbers or Struts

Tools Required: Torque wrench, spring compressor (if struts are being replaced).
Remove the bolts securing the shock absorber or strut to the lower control arm and upper mount.
If replacing struts, use a spring compressor to safely remove the coil spring from the strut assembly.
Install new shock absorbers or struts, ensuring proper orientation and alignment.
Torque all bolts to manufacturer specifications.

4. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove the floor jack.
Torque the lug nuts to the specified torque for the vehicle.

5. Final Check

Reconnect the battery.
Perform a test drive to ensure the suspension feels firmer and handles properly.
