Solution

1. Preparation

Gather necessary tools and ensure the work area is clean and safe.
Tools Required: Jack, jack stands, tire pressure gauge, alignment tools, socket set, torque wrench.

2. Tire Inspection and Replacement

Check tire pressure and inflate to the manufacturer’s recommended PSI.
Inspect tires for tread depth and uneven wear patterns.
If tires are damaged or worn, remove them using a socket set.
Replace with new tires if necessary, ensuring proper alignment of the tire beads.
Torque values: Tighten lug nuts to the manufacturer’s specified torque (typically around 80-100 ft-lbs).

3. Suspension Component Inspection and Repair

Lift the vehicle with a jack and secure it with jack stands.
Visually inspect control arms, bushings, and strut assemblies for wear.
Replace any worn or damaged components with OEM or high-quality aftermarket parts.
If struts are being replaced, ensure the new struts are pre-loaded properly according to specifications.

4. Wheel Alignment

After addressing tire and suspension issues, perform a four-wheel alignment.
Use alignment tools to adjust camber, caster, and toe settings to factory specifications.
Verify measurements and adjust as necessary.

5. Steering System Inspection

Inspect tie rods and the steering rack for any play or damage.
Replace any worn parts found during inspection.
Ensure that all connections are tight and properly torqued.
