Solution

1. Preparation

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

2. Inspect and Replace Worn Components

Inspect Shock Absorbers/Struts:
- Remove the wheels using a socket set.
- Check for leaks or physical damage on the shock absorbers.
- If damaged, remove the strut assembly by disconnecting it from the lower control arm and the top mount.
- Replace with a new shock absorber, ensuring it's torqued to manufacturer specifications.
Examine Bushings and Mounts:
- Look for cracked or hardened bushings.
- If bushings are worn, remove the suspension component to access the bushings.
- Press out the old bushings and install new ones using a bushing tool.
- Reassemble the suspension component and torque to specified settings.

3. Lubrication of Moving Parts

Apply Lubricant:
- Spray appropriate lubricant on all moving parts of the suspension, such as sway bar links and control arm joints.
- Ensure excess lubricant does not drip onto brake components.
