Solution

1. Preparation

Gather tools and required parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required: Jack stands, socket set, torque wrench, wheel chocks.

2. Tire Inspection and Replacement (if necessary)

Sub-steps:
1. Remove the wheel nuts using a socket wrench.
2. Inspect the tire for uneven wear or damage; replace if necessary.
3. If replacing, install new tires and tighten the wheel nuts to the manufacturer’s specifications (typically around 80-100 ft-lbs).

3. Suspension Component Inspection and Replacement

Sub-steps:
1. Remove any necessary underbody covers for access to suspension components.
2. Check shock absorbers/struts for leaks and physical damage; if damaged, remove them by unbolting from the top and bottom mounts.
3. Install new shocks/struts by reversing removal steps, ensuring to torque bolts to manufacturer specifications (typically around 15-30 ft-lbs).
4. Inspect and replace any worn bushings or control arms as necessary.

4. Wheel Alignment

Sub-steps:
1. After replacing suspension components, take the vehicle to a professional alignment shop.
2. Ensure the alignment is adjusted to manufacturer specifications to improve handling and tire wear.
