Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands for safety.

3. Inspect and Replace Components

A. Sway Bar Links

Remove the sway bar links: Use a socket set to remove the nuts securing the sway bar links.
Inspect the links: Check for wear or damage, replace if necessary with OEM or equivalent parts.
Install new sway bar links: Torque the nuts to the manufacturer’s specifications (typically around 30 ft-lbs).

B. Struts/Shocks

Remove strut assembly: Unbolt the strut from the upper mount and lower control arm, and disconnect any brake lines attached to the strut.
Inspect for leaks: Check for oil leakage or damage on the strut body.
Replace struts if needed: Install new struts, ensuring they are oriented correctly. Torque all bolts to specifications (usually around 50 ft-lbs for lower bolts and 20 ft-lbs for upper nuts).

C. Control Arm Bushings

Remove control arms: Unbolt the control arms from the subframe and the steering knuckle.
Replace bushings: Use a bushing press or appropriate tool to replace old bushings with new ones.
Reinstall control arms: Torque the bolts to the manufacturer's specifications (typically around 50 ft-lbs).
