Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and parked in a safe area.
Collect data from the alignment machine (if applicable).

2. Adjust Tire Pressure

Use a tire pressure gauge to check the pressure in all tires.
- Adjust to manufacturer specifications (found on the driver’s side door jamb).

3. Perform Wheel Alignment

Tools Required: Alignment machine, torque wrench, socket set.
Raise the vehicle using a lift and secure it.
Remove the front tires for better access to suspension components if needed.
Adjust the toe, camber, and caster angles as per manufacturer specifications:
- Toe: Adjust tie rod ends to achieve the correct toe angle.
- Camber: If adjustable, use camber bolts or shims to set the correct angle.
- Caster: Adjust if necessary using the control arm or strut mounts.
Torque all fasteners to the manufacturer’s specifications.

4. Inspect and Replace Worn Components (if necessary)

Check for any worn bushings, ball joints, or control arms.
If components are worn, replace them before redoing the alignment.
- Parts Required: Suspension bushings, ball joints, control arms (if needed).

5. Reinstall and Recheck

Reinstall wheels and ensure lug nuts are torqued to the manufacturer's specifications.
Lower the vehicle and perform a final check on alignment settings to verify adjustments.
