Hey all. I have a 18 DJ 4 cyl with 8x,xxx miles on it and am having an issue in reverse. The car has always shuddered and been a little loud in reverse. Just recently though, when backing up, even on flat surfaces, the rumble has gotten much worse. It’s embarrassingly loud and really shakes hard in reverse. Could bad motor or transmission mounts be the culprit? The motor visibly shakes front to back when in reverse with the hood open. I’ve also noticed a bit of shake when driving on highways at higher speeds but the is very intermittent. Thanks for any suggestions.
