Solution

1. Preparation

Gather all necessary tools and parts before starting.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Check Tire Pressure

Use a tire pressure gauge to check the pressure of each tire.
Inflate or deflate the tires to the recommended PSI as specified in the owner’s manual.

3. Inspect and Rotate Tires

Remove the front tires using a socket set.
Inspect for uneven wear and rotate tires if necessary, moving the front tires to the back and vice versa.
Reinstall the tires and tighten the lug nuts to the manufacturer’s torque specifications (typically 76-83 ft-lbs for most Toyota models).

4. Wheel Alignment

If the vehicle still pulls after tire adjustments, perform a wheel alignment.
Use an alignment machine or take the vehicle to a professional service.
- Adjust the camber, caster, and toe angles to the manufacturer’s specifications.

5. Inspect Suspension Components

If alignment doesn’t resolve the issue, inspect the suspension components.
Replace any worn or damaged parts, such as control arms, ball joints, or bushings, following proper procedures.
- For control arm replacement:
  - Disconnect the lower ball joint and the rear mount.
  - Remove the control arm bolts and replace with new parts, tightening to manufacturer specifications.
