I have a 2005 Wrangler TJ 4.0L, 6-speed with about 127K on it, getting a very very notable vibration from 10-18 or so mph and it happens with or without the clutch engaged. Had my uncle who is a mechanic just do a transmission mount on the vehicle and while he had it on the lift and said the vibration when he leaves it in first idling is very notable, he took out the drive shaft to check make sure it wasnt bound up or anything, his concern was that whatever it is possibly broke the transmission mount. not sure if anyone had any speculations? I would greatly appreciate any help possible.
