⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands to secure the vehicle when working under it.
•Ensure the vehicle is on a flat surface before performing tire and suspension work.

Symptoms

•Vibrations felt in the steering wheel or seats at speeds above 50 mph
•Steering wheel shake or wobble
•Increased noise from the tires or suspension
•Uneven tire wear
•Possible alignment issues
•Check engine light may be illuminated

Diagnostic Steps

1
Inspect tire pressure and ensure all tires are inflated to the manufacturer’s specifications.
2
Visually inspect tires for uneven wear patterns, bulges, or damage.
3
Check wheel balance by using a wheel balancer or taking the vehicle to a service center.
4
Examine suspension components (shocks, struts, bushings) for wear or damage.
5
Inspect wheel alignment using an alignment machine to check for deviations from specifications.
6
Test drive the vehicle to replicate the vibration and determine if it is speed-specific or occurs at other speeds as well.
