Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar, wheel chocks.
Ensure the vehicle is on a flat surface and the engine is off. Engage the parking brake and place wheel chocks behind the rear wheels.

2. Replace Worn Shocks/Struts

Sub-steps:
1. Loosen the lug nuts on the front or rear wheels.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the wheels.
4. Unbolt the top and bottom mounting points of the shock/strut using the socket set.
5. Remove the old shock/strut and replace it with a new one.
6. Torque the bolts to manufacturer specifications (usually around 40-50 ft-lbs).
7. Reinstall the wheels and lower the vehicle. Tighten the lug nuts to manufacturer specifications.

3. Replace Worn Bushings

Sub-steps:
1. Lift the vehicle and secure it with jack stands.
2. Use a pry bar to remove the old bushing from the control arm or sway bar.
3. Install new bushings, ensuring they are properly aligned.
4. Torque all bolts to manufacturer specifications.

4. Alignment Adjustment

Sub-steps:
1. Once components are replaced, take the vehicle to a certified alignment shop.
2. Ensure adjustments are made to the camber, caster, and toe settings to match manufacturer specifications.
