Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery if working on electrical components.

2. Tire Rotation and Balancing

Tools Required: Tire jack, jack stands, torque wrench, tire balance machine.
Raise the vehicle with a tire jack and secure it with jack stands.
Remove the wheels and inspect for uneven wear; rotate tires if necessary.
Mount the tires onto a tire balance machine and adjust weights to correct any imbalances.
Reinstall wheels and torque lug nuts to manufacturer specifications (typically 80-100 ft-lbs).

3. Alignment Adjustment

Tools Required: Alignment machine.
Use an alignment machine to check the angles of the wheels.
Adjust the camber, caster, and toe settings to match manufacturer specifications.
Recheck alignment after adjustments to ensure it is within the required range.

4. Suspension Inspection and Replacement (if needed)

Tools Required: Socket set, wrenches, strut spring compressor (if replacing struts).
Inspect suspension components for wear or damage. Focus on bushings, struts, and control arms.
If any components are worn, replace them with OEM or high-quality aftermarket parts.
Reassemble any components, ensuring all bolts are torqued to specifications.
