Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and turn off the engine.
Safety warning: Engage the parking brake and wear safety glasses.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure of each tire.
Inflate or deflate tires to match the specifications listed on the driver’s door jamb.

3. Tire Rotation

Remove the lug nuts using a socket set and impact wrench.
Rotate the front tires to the rear and vice versa to promote even wear.
Reinstall the lug nuts and torque them to the manufacturer's specifications (typically around 80-100 ft-lbs).

4. Wheel Alignment

Take the vehicle to a professional alignment shop for a four-wheel alignment.
Ensure that the technician uses a computerized alignment machine to adjust the camber, caster, and toe settings according to manufacturer specifications.

5. Suspension Inspection and Repair

If worn suspension components are found, replace them as necessary:
- Control Arms: Remove bolts using a socket set, then replace the control arms if damaged.
- Bushings: Press out the old bushings and press in new ones using a bushing tool.
- Struts/Shocks: Remove struts by unbolting from the top mount and lower knuckle, then replace with new struts.
