2. Inspect and Replace Shocks/Struts

Tools Required: Socket set, wrench set, jack, jack stands, torque wrench.
Sub-steps:
1. Lift the vehicle with a jack and secure it with jack stands.
2. Remove the wheel to access the shock/strut assembly.
3. Unbolt the upper and lower mounting points of the shock/strut.
4. Remove the old shock/strut and compare it to the new part for compatibility.
5. Install the new shock/strut, ensuring it is properly seated and aligned.
6. Torque the bolts to the manufacturer's specifications (refer to the service manual).
7. Reattach the wheel and lower the vehicle.

3. Replace Worn Bushings

Tools Required: Socket set, bushing removal tool (if needed), grease.
Sub-steps:
1. Identify the worn bushings by visual inspection or during shock/strut removal.
2. Remove the component holding the bushings (control arms, sway bars).
3. Use a bushing removal tool to extract the old bushings.
4. Install new bushings, applying grease if needed for easier installation.
5. Reinstall the component and torque to specifications.

4. Wheel Alignment

Tools Required: Alignment rack or alignment tool.
Sub-steps:
1. After all repairs, take the vehicle to a professional alignment shop or use an alignment tool.
