Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if necessary for electronic components.

2. Tire Inspection and Rotation

Tools Required: Floor jack, jack stands, lug wrench.
Raise the vehicle using a floor jack and secure it with jack stands.
Remove the tires and inspect for uneven wear patterns.
Rotate tires if applicable to balance wear across all tires.

3. Wheel Alignment Adjustment

Tools Required: Alignment machine or tools for measuring angles.
Reattach the tires to the vehicle and lower it to the ground.
Use the alignment machine to measure camber, caster, and toe settings.
Adjust the alignment according to the manufacturer's specifications, typically using adjustable control arms or tie rods.

4. Suspension Component Replacement (if needed)

Tools Required: Socket set, torque wrench, pry bar.
If any suspension components are worn, remove them using the socket set.
Replace with OEM or high-quality aftermarket parts, ensuring proper fitment.
Torque all bolts to the manufacturer's specifications.
