Solution

1. Tire Inspection and Adjustment

Check Tire Pressure: Use a tire pressure gauge to ensure all tires are inflated to the recommended PSI.
Inspect Tread Depth: Use a tread depth gauge to measure the depth and replace any severely worn tires.

2. Wheel Alignment

Preparation: Park the vehicle on a level surface and ensure tires are straight.
Adjust Alignment:
- Use an alignment machine to measure the camber, caster, and toe angles.
- Adjust to manufacturer specifications using the alignment adjustments on the control arms and tie rods.
- Tighten all adjustment bolts to the specified torque.

3. Suspension Component Inspection

Visual Inspection: Examine control arms, bushings, and tie rods for signs of wear or damage.
Replace Worn Components: If any components are damaged or excessively worn, replace them with OEM parts.
Reassemble and Torque: Ensure all bolts are torqued to the manufacturer's specifications.

4. Steering System Check

Inspect Steering Rack: Check for play in the steering rack or any leaks.
Replace Steering Components: If necessary, replace worn steering components such as the steering rack or tie rod ends.
Recheck Steering Alignment: After any replacement, ensure the steering alignment is still within specifications.
