⚠️ Safety Warnings

Important safety information - read before proceeding

•Ensure the vehicle is on a flat surface, and use wheel chocks to prevent rolling.
•Always secure the vehicle with jack stands.
•Always disconnect the battery if working on electric suspension systems.
•Allow the vehicle to cool before working on suspension components.

Symptoms

•Uneven tire wear
•Excessive bouncing or swaying during driving
•Noise from suspension components (clunks or rattles)
•Vehicle pulling to one side
•Difficulty steering or a loose steering feel
•Increased road vibrations felt in the cabin

Diagnostic Steps

1
Examine the suspension components including struts, shocks, control arms, and bushings for signs of wear, damage, or rust.
2
Check for uneven tire wear patterns which can indicate misalignment or suspension issues.
3
Push down on each corner of the vehicle and observe how many times it bounces. More than 1-2 bounces may indicate worn shocks or struts.
4
Take the vehicle on a test drive to assess handling, noise, and ride quality under various conditions (e.g., bumps, sharp turns).
5
Use an alignment tool to check if the wheels are aligned correctly; misalignment can indicate suspension problems.
6
With the vehicle safely lifted, check for excessive movement in suspension components by pulling and pushing on them to assess play or looseness.
