Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Gather safety equipment such as gloves and safety glasses.

2. Tire Pressure Adjustment

Tools Required: Tire pressure gauge, air compressor
Check and adjust the tire pressure to the recommended PSI found in the owner's manual or on the door jamb sticker.
Ensure all tires are inflated to the correct pressure.

3. Tire Rotation (if applicable)

Tools Required: Jack, jack stands, lug wrench
Loosen the lug nuts on all wheels while the vehicle is still on the ground.
Use the jack to lift the vehicle and place it on jack stands.
Rotate the tires according to the recommended pattern (e.g., front to back, side to side).
Tighten the lug nuts to the specified torque value (usually around 100-120 ft-lbs, check owner's manual for exact specifications).

4. Wheel Alignment

Tools Required: Alignment machine, torque wrench
Take the vehicle to a professional service center to have a computer-based wheel alignment performed.
Adjust camber, caster, and toe settings to the manufacturer's specifications.

5. Suspension Inspection and Repair

Tools Required: Socket set, wrenches, torque wrench
Inspect all suspension components for wear or damage.
Replace any worn or damaged components such as control arms, bushings, or shocks as necessary.
Reassemble and torque components to manufacturer specifications.
