im running the re 3.5 super flex now with the stock Dshaft. i had to drop the tcase an inch. as soon as funds free up for a SYE and shaft ill be swapping them on. Ive wheeled the hell out of the jeep for over 2 years with the stock dshaft with no vibes or issues
You'll be fine. I've got a 4" Pro-Comp lift with the stock ds and a tc drop kit and it's been ok. the only downside is that you'll hit a few more rocks when wheelin', but once you get over that sound, it's all good.
atleast you are asking this before installing the lift.. If you have a auto 4speed trans.. plan on getting an sye and shaft.. I did mines with the 1 inch tc drop and the vibes were still there.. Now after the sye.. I still have a humming noise around 50-60 mph. For some reason you get more vibes with a 4 speed trans.. I bet it is because the lenght from the shaft and the diff is a lot closer than a 5 or 6speed transmission.
yes it is the auto trans how bad was the vibes what was raw and surf do they have they auto or stick chris says get a xj driveshaft cutdown is it sheaper to go that way or should i just go ahead and buy new driveshaft
mknight.. I am definately sure you will need a sye.. Trust me its bad.. not even with a 1'' TC drop.. I had no issues with a 2'' spacer lift without a tc drop. but man with the 3.5 lift.. the slight vibes with the sye is annoying.. but livable.
I believe the 3 speed trans would have less vibes.. do a search. here and other jeep forums..
O and I tried everyhing.. different angles for the shaft and even rebalanced it.. I know its the shaft that still cause a slight humm, I pulled the rear shaft out and drove and it was fine..FTW
ok thanks it is a 05 so it has the od model i dont know if there is a length difference but it sounds like i just need to do it all at one time lift sye tires and rims then maybe i can run it with od off untill i get new gears looks like an easy way to spend 4 grand
