Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the vehicle is cool and allow time for any hot components to cool down.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on the area being inspected or repaired.
Secure the vehicle on jack stands for safety.

3. Inspect and Replace Shock Absorbers

Tools Required: Socket set, torque wrench, wrench set.
Remove the bolts securing the top and bottom of the shock absorber.
Carefully remove the shock absorber from its mounting.
Compare the old shock absorber with the new one to ensure compatibility.
Install the new shock absorber and torque the bolts to manufacturer specifications (typically around 30-40 Nm for upper mounts, check service manual for exact values).

4. Inspect and Replace Control Arms/Bushings

Remove the necessary components to access the control arms (may include wheels, brake calipers, or rotor).
Tools Required: Socket set, ball joint separator, torque wrench.
Remove the control arm bolts and take out the control arm.
Replace any worn bushings with new ones.
Reinstall the control arm and torque the bolts to manufacturer specifications.

5. Wheel Alignment

After replacing suspension components, have a professional wheel alignment performed to ensure proper handling and tire wear.
