    Hey guys, it seemsslike i have too many problems with my 91 k5 but here goes...

    I got my body lift on a week ago. The 4wd seemed to be working ok on the street so i took it out to do some light fourwheeling the other day. The 4wd was fine until i went down into this deep ditch and kindof jarrd my frontend. My 4wd stopped working and until i put it back into 2 wheeldrive it made a nasty grinding noise in both foward and reverse. When i finally got it out in 2 wheel drive i took it back home and havent messed with the 4wd since. Now i tried it out on the street today and whenever i give it gas, foward and reverse it still makes a nasty grinding noise. I put it in 4wd and got underneath and the shaft dosent spin, while it does in 2wd. When i spin the shaft in 2wd with my had it makes a similar grinding noise to the one i hear when i drive in 4wd.

    *GASP*

    Now that ive caught my breath here is a pic of my front Drive shaft.

    are the splines wore on the front driveshaft? it could be they are slipping, it makes one hell of a racket when they do it, when driveing anyway.

    can you pinpoint where the noise is coming from when you spin the shaft?

    How big of a body lift did you put on? More than likely you will need a new drive shaft and some sort of t-case lowering kit, or driveshaft spacers. I don't know if they make em for these, but I had a similar problem on my old samurai when I body lifted it.

    A body lift will not effect the driveshafts or t-case as they all stay in the same relation to each other, so I'm not sure where you are coming from at all.......

    Anyway, after installing the body lift did you check the adjustment on the t-case shifter. If you didn't adjust it then there is a good chance the shifter is hitting the body, shifter boot, etc... before fully engaging.

    I took it off because it was frozen up and giving me a hell of a time. Before i do any ajusting Is this the little bastard and how exactly do i adjust it? Do i just losten the nutz on both sides of the bolts and let the box go where it needs to and then tighten them back down?

    Thanks

    Pretty much just loosen one side(the way you need to move it) then tighten the other side up :waytogo:

    yeah sounds like your getting gear clash from being in nutral.

    the t case isent getting ingauged fully

    you may have to cut the shifter linkage and weld a spacer in or something along those lines

    I'd say you're on the right track. Those are the noises you get when the t-case is have engaged.

    pull the front driveshaft and pull the shaft apart, you will be able to see if the splines are wore or not. my money is on the splines.

    i bet you 200 bux its the t case,

    oh and by the way, what is the best route to go when replaceing a np241?

    should i have the transmission place rebuild it, replace it, get one from ck5 and do it myself.

    the guys said just to pull the tcase and to put it back in without repair is 190.

    i'd almost bet Darkshadow is right. makes perfect sense, and i've heard of guys having to cut the shifter hole bigger before...

    well it could be, the guys who looked at it didnt even crack it open. they just assumed and told me the case was bad
