Solution

1. Preparation

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

2. Inspect Suspension Components

Tools Required: Jack, jack stands, socket set
Raise the vehicle using a jack and secure it on jack stands.
Visually inspect the shocks and struts for leaks, damage, or excessive wear.
Check control arm bushings and sway bar links for signs of deterioration.

3. Tighten Loose Hardware

Tools Required: Torque wrench, socket set
Use a socket set to check and tighten all suspension-related bolts and nuts to the manufacturer’s torque specifications.
Pay special attention to the upper and lower control arm bolts, strut mounts, and sway bar end links.

4. Replace Worn Components

Parts Required: Replacement shocks/struts, bushings, or sway bar links (if necessary)
If any components are found to be worn or damaged, remove the old parts and install new ones.
Follow manufacturer specifications for torque values on new components.

5. Reassemble and Lower Vehicle

After inspection and repairs, reassemble any components that were removed.
Lower the vehicle carefully from the jack stands and perform a final check of all hardware.
