Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat, stable surface.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Shocks/Struts

Tools Required: Socket set, torque wrench, spring compressor (if needed).
Remove the wheel to access the suspension components.
Use the socket set to unbolt the top and bottom mounts of the strut.
If applicable, use a spring compressor to safely compress the coil spring before removing the strut assembly.
Inspect the strut for signs of leakage or damage.
Replace with new shocks/struts if necessary, ensuring all bolts are torqued to manufacturer specifications.

3. Check and Replace Worn Bushings

Remove any components obstructing access to suspension bushings (e.g., sway bar).
Inspect bushings for cracks, wear, or deterioration.
Use the socket set to remove bolts securing damaged bushings.
Install new bushings, ensuring proper orientation and fit.

4. Alignment and Tire Maintenance

After replacing suspension components, perform a wheel alignment.
Inspect all tires for proper inflation and tread wear.
Rotate or replace tires as needed, ensuring they are balanced according to specifications.
