Need Help!!! 06 TJ SE
 
First, I installed a 4 inch Pro-Comp Lift on my TJ SE and have some vibes coming from the rear drive shaft (around 30mph and 45-60mph). I installed the transfercase lowering kit and lowering bracket for the 4 wheel drive handle and my SYE and CV driveshaft is in the mail. Here is the question, should my front driveshaft be spinning even though it is in 2 wheel drive? Did my automatic locking hubs engage somehow? Is the vibration causing enough resistance to cause my automatic locking hubs engage? I was thinking about puting my jeep on a lift and puting it in drive to to see what happens. Any suggestions, ideas?

Have you changed to manual hubs on your front axle? Other wise then yes your front dshaft will always spin even in 2wd. Nothing in the TCase is making this happen it spins from the front. Since TJ's don't have manual locking hubs the front axle shafts are turning 100% of the time.

Apparently, 06 TJ's have automatic locking hubs. According to Cars.com 06 Wrangler TJ SE specs.

Automatic locking hubs according to Cars.com are:

Automatic locking 4WD wheel hubs
The spring-loaded hub automatically engages on the fly when the transfer case is shifted from 2-wheel drive into 4-wheel drive. The application of torque to the axle causes the mechanism inside the hub to slide in and lock.
Primary Benefit:
Automatic locking hubs are convenient for occasional off-roading or when road conditions are rapidly changing, and they eliminate the need to exit the vehicle to manually lock the wheel hubs.

So if i put it on a lift the front driveshaft and front tires will not spin in 2 wheel drive, correct?

Well then based on that info I have no idea. I was not aware that they made a "MAJOR" change to the Dana 30 for the 06 year.


I have to believe that is completely false. The Dana 30 has remained unchanged in both the XJ and TJ for quite awhile. There really isn't even a hub in my TJ. The outer shaft rides on a hub bearing bolted thru the knuckle.

If you get all 4 wheels off the ground and turn the back wheels, the front ones wont turn when in 2WD, and vise versa.
