•Possible noise from tires or suspension components during vibration

Diagnostic Steps

1
Inspect tire pressure and ensure all tires are inflated to the manufacturer's specifications.
2
Visually check all tires for signs of damage, such as bulges, cuts, or uneven wear patterns.
3
Perform a wheel balancing test using a tire balancing machine to check for imbalances.
4
Inspect the suspension components for wear or damage, including bushings, struts, and control arms.
5
Check the alignment of the wheels using a wheel alignment machine to determine if adjustments are necessary.
6
Test drive the vehicle under similar conditions to replicate the shaking and isolate the source.
