Important safety information - read before proceeding

•Disconnect the 12V battery before working on electrical systems.
•Allow sufficient time for components to cool before handling.

Symptoms

•Shaking or vibrations felt in the steering wheel or chassis when accelerating
•Unusual noises accompanying the shaking (clunking or grinding)
•Decreased acceleration responsiveness
•Potential pull to one side during acceleration
•Tire wear patterns that appear uneven or abnormal

Diagnostic Steps

1
Inspect tire condition and pressure; ensure they are properly inflated and free of damage.
2
Check wheel alignment and balance; inspect for any bent rims or misalignment.
3
Examine suspension components for wear or damage, including bushings, struts, and control arms.
4
Scan the vehicle’s onboard diagnostics for any error codes related to the drivetrain or motors.
5
Inspect the drive axles and connections for wear or damage, especially around the motor mounts.
6
Test drive to replicate the issue under controlled conditions and evaluate when the shaking occurs.
