I recently purchased a new to me 2004 Rocky Mountain edition wrangler 4.0 with 5 speed manual transmission with Dana 44 rear end. Previous owner installed 4â€Â� lift with double carden driveshaft. The lift only replaced the lower control arms and it has the stock uppers. I plant to eventually get adjustable arms next year but want to drive it now. The lift also used a 1.5â€Â� TC drop. So yesterday I added 4 washers under the skid plate to help rid the vibes. I replaced the transmission mount as it was shot as well. No more vibration but I have a question. When measuring the pinion angle, if I did it correctly, the pinion shows 11Â° and the driveshaft is 15Â°. Is is possible to not have driveline vibes at those angles?
