⚠️ Safety Warnings

Important safety information - read before proceeding

•Allow the vehicle to cool before working on it.
•Disconnect the battery before working on electrical components.
•Ensure the vehicle is securely supported on jack stands before beginning work on the suspension.

Symptoms

•Clunking or banging noises when driving over bumps
•Creaking or squeaking sounds during turns
•Excessive body roll or sway during cornering
•Uneven tire wear
•Vehicle feels unstable or bouncy
•Suspension feels stiffer or looser than usual

Diagnostic Steps

1
Inspect the suspension components visually for signs of damage or wear, including shocks, struts, and control arms.
2
Check for loose or missing hardware, such as bolts and nuts, on suspension parts.
3
Test the shock absorbers and struts by pushing down on each corner of the vehicle and observing rebound behavior.
4
Perform a bounce test to check for excessive bouncing; the vehicle should settle quickly after being pushed down.
5
Inspect bushings and joints for cracks, tears, or degradation.
6
Examine the sway bar and end links for looseness or wear.
