Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if working on any electrical components.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check all tires.
Inflate or deflate tires to the correct pressure as specified in the owner’s manual (usually found on the driver’s door jamb).

3. Wheel Alignment

Use an alignment machine to check the toe, camber, and caster settings.
Adjust the alignment according to the manufacturer’s specifications.
- Front toe: Typically around 0.0 to +0.10 degrees
- Camber: Usually between -0.5 to +0.5 degrees
- Caster: Generally +2.5 to +4.0 degrees
Tighten all adjustment bolts to the specified torque (usually around 50-70 ft-lbs, check specifications).

4. Suspension Inspection and Repair

Lift the vehicle using a jack and secure it with jack stands.
Inspect the control arms, bushings, and shock absorbers for wear.
Replace any worn or damaged components as necessary.
Reassemble and torque all bolts to factory specifications.

5. Steering System Inspection

Check the tie rods and steering rack for play or damage.
Replace any worn tie rods or steering components.
Ensure all bolts are torqued to the manufacturer's specifications.
