I keep reading different things . I have a 99 xj 231 tc auto. Does the tc need to be ingaged or in 2h or nuetral. Does the tranny need to be in nuetral. Do i have to pull the front yoke. transfer case still in car. Thanks

 

Put the transfer case in 4Low. This is how I did mine (99 w/ NP231) a week ago and it went smoothly. Yes, the transmission should be in neutral WITH YOUR WHEELS CHOCKED. Disconnect the front driveshaft and ziptie or wiretie it to the side; you'll need to be able to pull the front output shaft out a little when you remove and reinstall the chain on the inside of the transfer case.

i left the tcase in the truck ,an yes u need to remove front drive shaft,for 1 u need to move the shaft as said above,an 2 i used the front drive shaft in the rear

 

So If I am pulling front driveshaft I assume I am removing the yoke.

 

You don't have to completely remove the front DS unless you're going to use it as the rear DS.
I guess I'm saying just disconnect the transfer case end of the driveshaft and hang it to the side. I just put mine in 4High and drove on my front DS (after reconnecting it to the transfer case) until my new rear DS comes in.

 

yes, i used an electric impact wrench tht plugs into cig outlets...harbor freight 25 bucks..at first i wuz scared to tackle the sye but afterwerds it wuz pretty eassy

 

Seems like a complicated project, but it's not that bad if you have the time and diligence. Do everything by the instructions and take your time.

 

make sure u have all the tools u need .....an a good key word good pair of snap ring pliers....good luck....feel free to pm me if u need any more ,help i just did this last week,luckily i got a crown sye for 180
