4
Inspect the bushings and mounts for degradation or deterioration.

Solution

1. Preparation

Gather all necessary tools and parts.
Elevate the vehicle using a floor jack and secure it with jack stands.
Ensure the vehicle is on a flat surface for stability.

2. Inspect and Replace Suspension Components

Inspect Shock Absorbers:
- Remove the wheel to access the shock absorbers.
- Check for oil leakage and physical damage.
- If damaged, remove the shock absorber by loosening the top and bottom mounting bolts.
- Replace with new shock absorbers, tightening bolts to manufacturer specifications (typically 15-20 ft-lbs for top bolts, 35-40 ft-lbs for bottom bolts).
Examine Control Arm Bushings:
- Inspect the control arms for any cracks or separation of the bushings.
- If they are worn, remove the control arm by loosening the bolts connecting it to the chassis and the steering knuckle.
- Replace with new bushings or control arms as necessary.

3. Reassemble and Lower Vehicle

Reattach the wheel and torque the lug nuts to the specified torque (usually around 100-110 ft-lbs).
Lower the vehicle from the jack stands and remove the floor jack.
