Same here. I did have to clean mine out once though. All grease and dirt packed around it. I just used a piece of coat hanger and cleared the junk out.Mine does the same, but it only seems to do it if I try and go in reverse a little fast. If I just go slow it doesn't do it. So that does kind of seem like a motor mount. I bet it would just be jacking the engine oil pan up and unbolting the 2 bolts. ??? I have no idea though.
