Extension housing or sye?
I got a 1996 Jeep Xj with a np231 transfer case. I just recently put a 3" lift on and the drive shaft is slipping out of the shaft due to the fact I have the stock slip yoke. So my question is do I have to get an sye or can I just use a rear extension housing and get a seal to slip the yoke right in? It seems like it would be the same as an sye just kind of extending instead of shortening. Any inputs would be great!

Yeah I was hoping I could get away with a 3", but guess not. I can feel it when I put it in drive it hesitates to slip in. Would the extension work or just go with an sye?

A driveshaft from an AW4 D35 combo will be about 1" longer. AX15 manual trans will be another 2" longer. They need to be from 96+, older ones will be different again.
Also make sure the new shaft won't bottom out in the transfer case when rear end compresses or you'll be buying a new transfer case and/or rear pinion

Well the drive shaft is one problem of many I have now lol, but whenever I'm going faster than 35 mph or so and let off the gas it sounds like a grinding noise from under the drivers side area. Also happens to when I accelerate right after I let off. I inspected everything under there and no sign of anything damaged.
