Tools Required: Tire pressure gauge, air compressor.
Check and adjust tire pressure to the recommended PSI found in the driver’s side door jamb.

3. Alignment Adjustment

Tools Required: Wheel alignment machine, basic hand tools.
If the alignment is out of spec, adjust the camber, caster, and toe settings according to manufacturer specifications.

4. Inspect and Replace Worn Components

Tools Required: Jack, jack stands, socket set, torque wrench.
Lift the vehicle and securely support it on jack stands.
Inspect control arms, bushings, and tie rods. Replace any worn or damaged components as necessary.
Ensure all bolts are torqued to manufacturer specifications.
