Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and goggles for protection.

2. Tire Balance

Remove the wheels from the vehicle using a socket set and impact wrench.
Mount each wheel on a wheel balancer.
Add wheel weights as necessary to balance each wheel according to the balancer's readings.
Reattach the wheels to the vehicle, tightening lug nuts to the manufacturer’s torque specifications (typically around 80-100 ft-lbs).

3. Wheel Alignment

Place the vehicle on an alignment rack.
Adjust the front and rear toe, camber, and caster angles according to the manufacturer's specifications.
Ensure that each adjustment is locked in place and double-check alignment readings.

4. Suspension Inspection and Repair

Inspect all suspension components for wear, including control arms, bushings, and struts.
Replace any worn or damaged components with OEM or quality aftermarket parts.
Reassemble any disassembled parts and ensure all bolts are torqued to specifications.
