I own a 96 Grand Caravan. Accelerating from stop in either direction forward or backward, or hard turns I hear this like crunching sound coming from the Front Right. I have replaced the CV shaft on the right with no luck. I replaced the hub / bearing assembly on same side with no luck. What else could this be? It only happens if I accelerate rapidly from a stop. My driveway is on a steep slope and when I back out of it Ill hear the crunching also as I try to accelerate out of the driveway. There is no noise when driving along only at turns and taking off. Any help would be appreciated before I start throwing more money at it trying to find it.

 

Could be a sway bar link or bushings, also ck the spring on the strut could be hitting the strut support on the body.

 

THanks for the suggestions. What about upper strut mount and upper bearing? Could that possibly be the problem as well?
