Solution

1. Preparation

Gather tools and parts necessary for suspension inspection and repair.
Tools Required: Jack and jack stands, socket set, torque wrench, wheel chocks, suspension fork, alignment tools.
Safety Warnings: Ensure the vehicle is on a level surface and secured before working under it.

2. Inspect and Replace Shocks/Struts

Inspect Shocks/Struts:
- Remove the wheel using a socket set.
- Visually inspect the shocks/struts for signs of leakage or physical damage.
Replace if Necessary:
- Disconnect the upper and lower mounting bolts using a socket set.
- Remove the old shock/strut assembly carefully.
- Install the new shock/strut in the reverse order, ensuring all bolts are torqued to manufacturer specifications (check repair manual for specific torque values).

3. Check and Replace Bushings

Inspect Bushings:
- Look for cracks, tears, or significant wear on control arm bushings and sway bar links.
Replace if Necessary:
- Remove the affected component (e.g., control arm) using the appropriate socket sizes.
- Press out the old bushing using a suspension fork or bushing tool.
- Install the new bushing and reassemble the component, ensuring all bolts are tightened to specifications.

4. Wheel Alignment

After repairs, perform a wheel alignment to ensure proper handling and tire wear.
Adjust camber, caster, and toe settings as required, following manufacturer specifications.
