So I was offroading today ( I will put up another thread in a few with pictures) and this happened prior also a week ago. I was going to pull my boss's van out of this grass driveway and I engaged 4 hi ( I have had previous problems with t case staying in 4hi because of it popping out) and put it in reverse to pull him out and I got going and then I hurd a pop from the t case and wasent sure what it was and I just put it in 2 and didnt worry about it. Today, I had a hard time keeping it in 4 hi untill I almost got stuck then was stopped and put it in 4 low and it wouldnt stay in there either with grinding so I put it back into 4 hi and it stayed for the rest of the trip in 4 hi so is it just a matter of me putting the t case in neutral then putting it in 4hi and I know that if I put it in 4 low in need to be moving so thats probly the answer for the grinding and not staying in 4 low so I think im good with looking at the linkage but wasent sure in general what to do. But, once I got it into 4 hi today it didnt pop out and the jeep was on and off throughout the day so it was good. Just wondering if im on the right track and by the way, its all pretty much stock with 30s no driveline mods. Thanks, Joey.
