Solution

1. Preparation

Tools Required: Floor jack, jack stands, torque wrench, tire pressure gauge, wheel alignment machine.
Lift the vehicle using a floor jack and secure it on jack stands.

2. Tire Inspection and Adjustment

Check tire pressure using a tire pressure gauge; inflate tires to the recommended PSI.
Inspect all tires for signs of uneven wear; replace if necessary.

3. Wheel Alignment

Position the vehicle on a wheel alignment machine.
Adjust the alignment settings according to manufacturer specifications.
- Front Camber: +0.5 to +1.0 degrees
- Front Toe: 0.08 to 0.12 degrees
- Rear Camber: -0.5 to -1.0 degrees
- Rear Toe: 0.10 to 0.15 degrees

4. Suspension Inspection and Repairs

Inspect the suspension components visually for signs of wear or damage.
If any components (e.g., shocks, struts, bushings) are damaged, replace them:
- Shocks/Struts: Remove the lower and upper bolts, replace with new units, and torque to manufacturer specifications (usually around 50-70 ft-lbs).
- Bushings: Remove the old bushings using a bushing removal tool, install new bushings, and ensure correct orientation.

5. Steering System Check

Inspect tie rods for play; if worn, replace them.
Check the steering rack for leaks or damage and replace if necessary.
