Solution

1. Preparation

Gather Tools and Materials: Obtain a jack, jack stands, socket set, torque wrench, pry bar, and a suspension bushing tool.
Safety Precautions: Ensure the vehicle is on a flat surface, engage the parking brake, and wear safety glasses.

2. Replace Worn Shocks/Struts

Remove Old Shocks/Struts:
1. Lift the vehicle and secure it with jack stands.
2. Remove the wheel to access the suspension components.
3. Unbolt the top mount of the shock/strut assembly.
4. Remove lower bolts connecting the assembly to the control arm.
Install New Shocks/Struts:
1. Position the new shock/strut assembly in place.
2. Torque the lower bolts to manufacturer specifications (typically around 40-50 ft-lbs).
3. Secure the top mount and tighten to the specified torque (usually around 20-30 ft-lbs).

3. Replace Worn Bushings

Remove Old Bushings:
1. Use a pry bar to remove the control arm from its mount.
2. Cut or press out the old bushings using a bushing tool.
Install New Bushings:
1. Lubricate the new bushings and press them into place.
2. Reattach the control arm to the suspension and torque bolts to manufacturer specifications.

4. Alignment Adjustment

Check Alignment:
1. After replacing components, take the vehicle to a professional for a four-wheel alignment to ensure proper handling and tire wear.
