Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the 12V battery to avoid electrical issues while working on the suspension.

2. Inspect and Replace Shock Absorbers

Sub-steps:
1. Lift the vehicle using a hydraulic jack and secure it with jack stands.
2. Remove the wheels to gain access to the suspension components.
3. Inspect the shock absorbers for leaks or physical damage.
4. If replacement is needed, remove the top and bottom mounting bolts of the shock absorber using a socket set.
5. Install the new shock absorber by reversing the removal steps; ensure bolts are torqued to manufacturer specifications (typically around 40-50 ft-lbs).

3. Replace Worn Bushings

Sub-steps:
1. Identify any bushings that appear cracked or worn.
2. Use a bushing removal tool to carefully remove the damaged bushings from their housings.
3. Lubricate the new bushings (if required) and press them into place using a bushing press.
4. Reassemble suspension components and torque all bolts to specifications.

4. Reassemble and Lower Vehicle

Sub-steps:
1. Reinstall the wheels and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to 100 ft-lbs in a star pattern.
3. Reconnect the 12V battery.
