Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under the vehicle to prevent accidents.
•Allow tires to cool before measuring tire pressure to get accurate readings.

Symptoms

•Noticeable differences in tread depth across the tires
•Crooked steering wheel when driving straight
•Vibrations or noise while driving
•Increased road noise
•Poor handling or traction

Diagnostic Steps

1
Inspect tire pressure on all four tires and adjust to recommended levels.
2
Visually examine all tires for signs of uneven wear patterns (e.g., feathering, cupping).
3
Check for proper wheel alignment using an alignment machine.
4
Inspect suspension components for wear or damage (e.g., bushings, struts).
5
Test drive the vehicle to assess handling and steering response.
6
Review maintenance records for missed rotations or alignments.

Solution

1. Preparation

Tools Required: Tire pressure gauge, jack, jack stands, alignment machine.
Ensure the vehicle is parked on a level surface and the engine is off.
Allow tires to cool before measurement.

2. Tire Pressure Adjustment

Sub-steps:
1. Remove valve caps from each tire.
2. Use the tire pressure gauge to measure the pressure.
3. Inflate or deflate tires to meet the manufacturer's recommended PSI, typically found on a sticker inside the driver’s door.
4. Replace the valve caps securely.

3. Tire Rotation

Sub-steps:
1. Loosen lug nuts slightly while the vehicle is still on the ground.
2. Lift the vehicle using a jack and secure it on jack stands.
3. Remove the tires and rotate them according to the appropriate pattern (e.g., front to back and side to side).
4. Reinstall the tires and hand-tighten the lug nuts.
5. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.

4. Wheel Alignment

Sub-steps:
1. Drive the vehicle onto an alignment rack.
2. Follow the machine’s instructions to set up alignment parameters.
3. Adjust camber, caster, and toe settings to manufacturer specifications.
4. Test the alignment with the machine and confirm settings are within tolerance.

5. Suspension Inspection

Sub-steps:
1. Visually inspect struts and shocks for leaks or damage.
2. Check control arms and bushings for wear or cracks.
3. Test the suspension components for play or movement using a pry bar.
4. Replace any worn or damaged components as necessary.
