Many thanks to everyone who commented. I will check motor and trans mounts, wheel balance and wheel appearance, and the leaf springs. The mounts might be the problem. Within the last several drives when shifting into reverse there has been, on occasion, a large bang in the rear(not just the regular Chrysler clang in the differential). Perhaps the trans is moving too much. Rob __________________________________ Do you Yahoo!? Read only the mail you want - Yahoo!
