I have a 93 ZJ with the double cardigan u joint at the t case. Mine was making a wierd squeaking noise and looks like it could use a rebuild, has anyone taken this thing apart? Also I have the front drive shaft out for now and parked on a small incline, and the jeep after about 1 hour or so it had rolled back about 10 feet, anyone ever seen this? <img src="/forums/images/graemlins/confused.gif" alt="" /> Any help would be appreciated.

Thanks
