I have a 96 Sentra GXE. I removed the left drive axle and changed out the outer cv joint boot. I have the drive axle back together again and am at the point of inserting it into the transfer case. It has a circlip at the proper place attached to the end of the splines where it enters the case. It only goes so far and then stops. I tried pushing on it a bit ... but no go. There is no place to hit on it or anyway to get any leverage. How do you get the damn thing in?? I read a previous post on this topic and the write-up indicated that all I have to do is push it in with some force. Is that it... or is there something else??
