Damaged Inner CV Joints Can Cause Vibration on Acceleration Damaged inner CV joints cause vibrations on acceleration and are very difficult to diagnose because the damage is so inconspicuous. You can only see it once the inner CV joint is removed from the vehicle and cleaned of all grease and debris.
What does a differential vibration feel like?
While sudden, catastrophic gear failures are exceedingly rare on standard applications that are not abused, most differential failures involve whining, grinding, or rumbling noises either upon acceleration when the differential is loaded, similar noises when the vehicle is coasting, or in severe cases, a rumbling or …
