Solution

1. Preparation

Gather tools and parts required.
Park the vehicle on a flat, level surface and engage the parking brake.
Safety warning: Ensure the vehicle is securely supported on jack stands before beginning any work.

2. Tire Inspection and Replacement

Sub-steps:
- Check the tire pressure using a tire gauge and inflate to the recommended PSI.
- Inspect tire tread for uneven wear patterns; replace tires if worn beyond specifications.
- Ensure all four tires are balanced and aligned; if necessary, take to a professional for alignment.
Tools Required: Tire pressure gauge, floor jack, jack stands, and tire iron.

3. Suspension Component Replacement

Sub-steps:
- If shocks or struts are faulty, remove them by detaching the upper and lower mounts.
- Replace with new, manufacturer-recommended shocks/struts.
- Reassemble the suspension components and torque to manufacturer specifications (usually around 15-25 ft-lbs for upper mounts, and 50-70 ft-lbs for lower mounts).
Tools Required: Socket set, torque wrench, and spring compressor if necessary.

4. Alignment and Final Checks

Sub-steps:
- After replacing suspension components, have the vehicle's alignment checked and adjusted.
- Re-inspect tires for proper inflation and alignment status.
Tools Required: Alignment machine (professional service recommended).
