Wear safety glasses and gloves for protection.

2. Adjust Tire Pressure

Check tire pressure with a gauge.
Inflate or deflate tires to match the manufacturer’s specifications found in the owner’s manual or on the driver’s side door jamb.

3. Wheel Alignment

Tools Required: Alignment machine, torque wrench, socket set.
Loosen the bolts on the tie rods.
Adjust the alignment settings according to manufacturer specifications using the alignment machine.
Tighten the bolts to the specified torque values.

4. Inspect and Replace Worn Components (if necessary)
