Affected Component

Suspension

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical systems.
•Ensure the vehicle is securely lifted and supported when working under it.

Symptoms

•Unusual noises from the suspension during driving (clunking or banging sounds)
•Vehicle pulling to one side while driving
•Excessive body roll or instability during cornering

•Warning messages related to the suspension on the dashboard
•Vibration or shaking felt in the steering wheel at certain speeds

Diagnostic Steps

1
Inspect the suspension components visually for any obvious damage or wear, such as broken springs or leaking shocks.
2
Use a diagnostic scan tool to check for any error codes related to the suspension system.
3
Perform a bounce test on each corner of the vehicle to assess shock absorber performance.
4
Measure the ride height at each corner of the vehicle to ensure it is within manufacturer specifications.
5
Check the alignment settings using a wheel alignment machine to detect any misalignment.
6
Inspect tire condition and pressure, looking for signs of uneven wear or under-inflation.

Solution
