Solution

1. Preparation

Gather tools required for the repair, including a jack, jack stands, tire pressure gauge, and alignment tool.
Ensure the vehicle is parked on a level surface, and the engine is off.
Safety Warning: Always engage the parking brake before lifting the vehicle.

2. Adjust Tire Pressure

Use a tire pressure gauge to check the pressure of each tire.
Inflate or deflate tires to match the recommended pressure found in the driver’s side door jamb label.

3. Perform Wheel Alignment

Lift the vehicle using a jack and secure it with jack stands.
Remove the front wheel covers if necessary to access the alignment adjustments.
Adjust the camber, caster, and toe angles using an alignment tool per the manufacturer's specifications.
- Camber: Adjust to 0° to +1° for optimal handling.
- Caster: Adjust to +3° to +5° for stability.
- Toe: Adjust to +0.05° to +0.15° for tire wear balance.

4. Inspect and Replace Suspension Components

Visually inspect all suspension components for wear, cracks, or play.
Replace any worn or damaged parts with OEM or equivalent parts.
- Common components: Tie rod ends, ball joints, and control arm bushings.
Torque new components to specifications as defined in the service manual.

5. Rotate Tires

If uneven wear is noted, rotate the tires according to the manufacturer's rotation pattern.
Ensure that the front tires are moved to the rear and vice versa, or cross-rotate if recommended.
Check lug nut torque after driving for a short distance to ensure proper seating.
