Broke Today at the Badlands

[Billy_bottle_caps]

Just got home from the Badlands about an hour or so ago. Had a great time but broke a couple things :cry: I was playing in the sand having a good time , and the rearend let go. Stock Dana 35 that with a welded diff. Knew they wen't that strong but didn't think I would break one in the sand with just 235's on! drove it out of the sand and by the time I got back up to the trailer, I think the t-case let go, cause I had no forward or reverse motion. Never had a MJ t-case apart before, does is there a chain in there? Do they tend to break or come off? Thanks for any input.

There's a chain in there which is what drives the front axle. You still should have power to the rear axle with a broken chain

No didn't have anything at the end.

You mean the driveshaft stopped turning?????

 

Cause if it was still turning, I would bet you either stripped the ring gear, or trashed the spider gears...

I think I stripped the ring gear and or the spider gears in the sand. It would still pull itself using only the front wheels till I got to the trailer and then there was a pop sound, and I had nothing. Moved the lever 2H 4H 4L, nothing in any of them. Do driveshafts moving at all. Hopefully just broke the chain in the t-case.

Np 231s are cheap enough. It'd probably be easier to just get another non-thrashed one. Make sure it has the right spline count.

If you have a vacume disconnect front end check that the vacume lines didnt come off or you might have popped something in the front end as well. If your 231 is trashed, I have a 91 NP 231 from my XJ that has been rebuilt with all new bearings, seals, and chain with a JB Conversions HD SYE with 20k miles on it. I got a Stak 3 speed so I'm looking to sell this case. PM me if interested.

Thanks for the tip! I will just look and see what the spline count is and go fromt there.

easiest way to tell is by the year/tranny.

 

a 1990 aw4 will have 21 spline all years from 91+ aw4 will have 23 spline

a ba10 manual will have 21 spline (89 changes to the ax15 and if you have ax15 it will be 23 spline)

Great at least now I know what to look for at the Pick N Pull! Thanks!
