⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under a vehicle to prevent collapse.
•Ensure the vehicle is in 'Park' and on a flat surface before performing any tire work.

Symptoms

•Steering wheel shakes or vibrates at speeds above 60 mph
•Uneven tire wear visible on front or rear tires
•Vehicle pulls to one side during driving
•Noise or vibration felt through the floorboards at high speed
•Check tire pressure warning light may be illuminated

Diagnostic Steps

1
Inspect tire pressure on all four tires using a tire pressure gauge.
2
Visually inspect tires for uneven wear patterns and damage.
3
Perform a wheel balance test using a digital wheel balancer.
4
Check the vehicle's alignment using an alignment rack.
5
Inspect suspension components (tie rods, control arms, bushings) for wear or damage.
6
Test drive the vehicle to confirm symptoms and check for changes in behavior after any adjustments.

Solution

1. Preparation

Gather tools: tire pressure gauge, jack and jack stands, wheel balancer, alignment equipment, torque wrench.
Ensure the vehicle is on a level surface and the parking brake is engaged.

2. Check and Adjust Tire Pressure

Use a tire pressure gauge to check all tire pressures.
Inflate tires to the manufacturer's recommended PSI found in the door jamb or owner's manual.

3. Inspect and Replace Tires (if necessary)

Check for uneven wear; if tires are worn beyond the tread indicators, replace them.
If only one tire is damaged, consider replacing it with a matching tire to maintain balance.

4. Balance Wheels

Remove the wheels using a socket set.
Mount each wheel on the wheel balancer to identify heavy spots.
Add appropriate weights to balance the wheels and reinstall them.

5. Perform Wheel Alignment

Using alignment equipment, adjust the camber, caster, and toe settings to factory specifications.
Tighten all components to the manufacturer’s torque specifications.

6. Inspect and Repair Suspension Components

Visually inspect tie rods, control arms, and bushings for signs of wear.
Replace any worn or damaged components as necessary, ensuring proper torque values during reinstallation.
