Affected Component

Suspension

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under a vehicle.
•Ensure the vehicle is on a level surface before lifting.

Symptoms

•Excessive bouncing or swaying during driving
•Uneven tire wear patterns
•Noises such as clunking or popping when driving over bumps
•Steering wheel vibration or misalignment
•Vehicle pulling to one side while driving
•Difficulty in maintaining control during turns

Diagnostic Steps

1
Check for any obvious signs of damage or wear on suspension components such as struts, shocks, control arms, and bushings.
2
Verify that all tires are inflated to the recommended pressure to rule out issues caused by improper inflation.
3
Push down on each corner of the vehicle to see how it rebounds. A vehicle that bounces more than once indicates worn shocks or struts.
4
Look for any oil or fluid leaks around the shock absorbers and struts, which could indicate a failure.
5
Use a wheel alignment tool to check if the wheels are aligned properly and to see if any adjustments are needed.
6
Drive the vehicle over different surfaces to listen for unusual noises and feel for handling issues.
