Solution

1. Preparation

Gather all tools and parts needed for inspection and repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.

2. Tire Inspection

Remove all four tires using a lug wrench.
Inspect each tire for uneven wear patterns indicating misalignment or suspension issues.
Measure tire pressure with a tire gauge and inflate to the manufacturer's recommended PSI.
Replace any tires that show significant wear or damage.

3. Alignment Adjustment

Set the vehicle on an alignment rack.
Adjust the camber, caster, and toe settings to match manufacturer specifications.
Tighten all adjustment bolts to specified torque values (typically between 50-70 ft-lbs, depending on the vehicle).
Perform a test drive to confirm improved handling.

4. Suspension and Steering Inspection

Visually inspect shock absorbers for leaks and ensure they are functioning properly.
Check control arms, bushings, and ball joints for wear and replace if necessary.
Tighten any loose bolts in the suspension and steering system.

5. Steering Linkage Repair

Inspect tie rods for play or damage.
If damaged, remove the tie rod end using a tie rod puller and replace with a new component.
Ensure all steering components are properly lubricated and free of debris.
