Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety glasses and gloves.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle as needed.
Support it securely with jack stands.

3. Inspect and Replace Components

Front Suspension:

Inspect: Check the struts, control arms, and sway bar links for wear.
Replace: If any components are damaged:
- Remove the wheel to access the suspension.
- Unbolt the strut assembly using a socket set.
- Replace the strut or control arm as necessary.
- Reassemble and torque the bolts to manufacturer specifications (typically around 40-70 ft-lbs for strut bolts).

Rear Suspension:

Inspect: Examine the rear shocks, springs, and bushings.
Replace: If faulty:
- Remove the wheel and access the rear shock mounts.
- Unbolt the shock absorber and replace it.
- Reassemble, ensuring all bolts are tightened to manufacturer specifications.

4. Final Assembly

Reinstall the wheels and lower the vehicle.
Tighten lug nuts to specified torque (typically 80-100 ft-lbs).
