When I push the 4 HI button a few seconds later I get a loud clunk that sounds like it is coming from the rear end. There is no problem shifting back to 2HI. I tried shifting into 4 hi while the the truck was under strain of a bad sandy road and again when I was on a smooth road for comparison. Both times I got the loud clunk once I pushed the 4 HI button. Driving around in 2 hi I have no problem. I've changed the front and rear Differential fluid, transfer case fluid and transmission fluid. Any help would be appreciated.
have the same problem?
