Does this look right?

Hey all,

I recently replaced the Rear u-joint on my jeep (4.0L) and I was wondering if the shaft was suppose to stick that far out?


Also, I found a hose that connects to the driver side of my transmission and run over it and to the passenger side but it doesn't go to anything and it has a hole in it.

What hose is this? Where is it suppose to go?

Thank you all in advance.

Its suppose to stick out that far due to the lift.

Possibly a vent hose.

So should I be concerned about it or just say it's suppose to be like that? I just don't want to tear anything up.

You have a 4" lift. It's gonna hang out some. Do you have any driveline vibration? That may be what helped kill your u joint. Have it lengthened a bit. or for big money sye and cardan slip ds. Then you could get rid of the transfer case drop kit.

Thanks for the input. I have been looking at SYE's but I'm not quite there yet.

Any thoughts on the transmission hose?

Vent hose. I have one in my trans set up just like that.

No that's pretty far. I almost tore out my DS when I first put my lift in and it was sticking out that far. At full flex I was pissing tcase fluid from the slip yoke when one side "unseated." Either do a tcase drop, a MML, or an SYE/CV shaft (best idea).

Do you have vibes?

Cheers

What's the measurement from the back of the extension housing to where the polished part of the driveshaft ends? My driveshaft is just over 4" long. You want at least half, if not more, of that length inside the extension housing. If you have less than 2" inside the extension housing, you may very well drop the driveshaft at a very inopportune time.

A test would be to:
-- Pull the rear driveshaft and record the overall length
-- Reinstall and measure how much you have outside the extension housing (this will tell you how much you have inside)
-- Lift the back of the Jeep allowing the rear axle to hang, extending your driveshaft as far as it can go, then remeasure

It's the safest way to ensure you won't have a disconnect on the trail or while going over a speed bump (yes, it happens. Happened to my son in the high school parking lot with our first YJ)

I'm guessing that you didn't notice that stick-out prior to your u-joint replacement...the new u-joint didn't create that gap.
My vote is SYE and a reworked XJ front shaft. It will run about $350 for everything and you can get rid of the TC drop. The SYE install isn't awfully difficult.
