Solution

1. Preparation

Gather tools and parts needed for the repair, including a torque wrench, jack and jack stands, tire pressure gauge, and alignment machine.
Ensure the vehicle is on a level surface and the engine is off.
Disconnect the battery if working on electrical components.

2. Tire Balancing

Remove the wheel from the affected axle using a socket set.
Mount the wheel onto a tire balancer and spin to check for imbalance.
Add wheel weights as necessary to correct any imbalance.
Reinstall the wheel and torque the lug nuts to the manufacturer's specifications (typically around 80-100 ft-lbs).

3. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure of each tire.
Inflate or deflate tires to the recommended pressure (usually found in the owner’s manual or on the door jamb sticker).
Recheck pressure after adjustments.

4. Wheel Alignment

Use an alignment machine to measure the current alignment specifications.
Adjust the toe, camber, and caster settings as needed to meet manufacturer specifications.
Test drive the vehicle to confirm alignment adjustments.

5. Suspension Inspection and Repair

Inspect all suspension components including tie rods, control arms, and bushings for wear or damage.
Replace any damaged components as needed, following the manufacturer’s torque specifications for assembly.
Recheck the alignment after replacing any suspension parts.
