rear drive shaft removal

I was told that I can remove my rear drive shaft on my TJ and not lose all my transfercase fluid. I think this is true on 97 and up. Was there a change in the Transfer case on the TJs with the slip yoke that allows for this?


The above post is my opinion and I have no facts to prove it... :)~

That is a YJ you are thinking of. Just take the straps off the yoke and a big screwdriver under the u-joint to unseat it and pull off the t/c.

to remove simply undo the straps on the yoke, remove the two u-bolt straps on the lower part of the shafts towards the rear, pull the driveshaft away from the t-case and its off... thats how i did it to replace the u-joints.

To clarify, the TJ's driveshaft can be removed without the t-case leaking. It's the '95 and older YJ that leaks the ATF out of the t-case if the driveshaft is removed.

I've had mine on and off a dozen or so times.
Have a roll of duct tape handy.
When you disco the back of the DS (where it goes into the joint on the rear diff)
Tape those caps on so they don't pop off and splay your needle bearings all over the floor.

Kindly then, answer me this: If you remove the rear driveshaft from a 97-newer Wrangler, is it safe to drive the vehicle without the driveshaft? I have had the front driveshaft out of my 97 for about 5 days now, waiting for a rebuild. No problems. Just wondering if it could be done the other way around - no rear shaft, operating on just the front shaft.

DC4WD told me it would be alright. I'm skeptical however. The reason I asked is because I'm now without my Jeep until my rear DS is made as I just installed my SYE. That is a good question and I'm glad you asked, I'm curious as well.

Yes, a TJ can be safely driven without the rear driveshaft... definitely. Safely as in nothing will happen to the transfer case, rear differential, front axle, etc.. Now if there is a locker in the front axle, then it would be engaged during the time the TJ is in 4wd which would make the steering difficult on the street.

So even at freeway speeds it will be alright? I'm talking like on the 15.

be careful

If you drive without the front drive shaft you must put the transfercase in 4Hi, so the chain will spin the pump. The fluid pump is on the front driveshaft side of the transfercase. Without the driveshaft to spin the transfercase it will overheat. And chain failure will happen.

Not really. The TJ's NV231 transfer case has a true neutral for the front driveshaft mechanism when in 2wd and it doesn't need the front driveshaft spinning to lubricate that part of the mechanism. If that weren't the case, the thousands of us running unlocked manual hubs on the front axle that stops the front driveshaft from spinning in 2wd would have beaucoup t-case problems.

Hummm!

Jerry,

Make sense when you put it that way, but that is different that what I was told.
Maybe it was the rear drive shaft that spins the pump?

Hummm!
