Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Ensure the vehicle is cool and disconnect the battery for safety.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure of all tires.
Inflate or deflate tires to the manufacturer's recommended pressure (found on the driver's side door jamb).

3. Alignment Adjustment

Tools Required: Wheel alignment machine, torque wrench.
Set up the vehicle on the alignment rack.
Adjust toe, camber, and caster angles according to manufacturer specifications.
- Front Toe: Typically between 0.05 to 0.10 degrees.
- Camber: Should be within 0 to -0.5 degrees.
- Caster: Should be positive and within specifications.
Tighten all adjustment bolts to the specified torque values.

4. Suspension Component Replacement (if needed)

If any suspension components (tie rods, ball joints) are worn, replace them.
Tools Required: Socket set, wrench set, ball joint separator.
Remove the damaged component:
- Loosen the retaining bolts and nuts.
- Use the ball joint separator to disconnect the ball joint from its socket.
Install the new component:
- Position the new part and secure it with the bolts.
- Torque bolts to manufacturer specifications.
