Re: thumping sound in front end, questions???

Generally carrier bearings will change their tune when loading changes (like abruptly going from accel to decel), and will make the most noise or vibration right at the transition from loaded to free (like just as you come up to cruising speed, or just as the clutch begins to disengage).


It's easier to feel in a RWD, because the length of the shaft amplifies the vibration, halfshafts don't put near the same loading on carriers.

I bet that's your problem, though. Can you loosen it's mounting slightly, and drive it a short distance, see if the nature of the sound changes? That might nail it.
