Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and allow the tires to cool before inspecting.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure in each tire.
Inflate or deflate tires to match the manufacturer's recommended psi found in the owner’s manual or door jamb sticker.

3. Wheel Alignment

Use an alignment rack to check the alignment specifications (camber, caster, toe).
Adjust alignment angles as needed using the adjustment bolts on the suspension components.
- Camber: Adjust the top of the wheel in or out.
- Toe: Adjust the angle of the tires relative to the centerline of the vehicle.
- Caster: Adjust the angle of the steering axis.
Torque adjustment bolts to manufacturer specifications (typically around 80-100 ft-lbs).

4. Suspension Inspection and Replacement

Inspect shocks and struts for leaks or damage.
If worn, replace with OEM or high-quality aftermarket parts.
Check control arms and bushings for signs of wear; replace if necessary.
Ensure all bolts and nuts are tightened to the specified torque.

5. Tire Rotation and Balancing

Rotate tires front to back or side to side based on the wear pattern.
Use a tire balancer to ensure all tires are properly balanced.
Reinstall tires and torque lug nuts to manufacturer specifications (typically 80-100 ft-lbs).
