4-Hi not working - bad T-Case?


For about 2 months now my 4 wheel drive has not been functioning properly. When I shift into 4-hi from a cold start it works fine, and from my experience it works until I hit a bump, then all of a sudden I start hearing some major grinding from the front end until I push down the clutch and shift back into 2-hi. 4-lo works perfectly from my experience but I haven't tested it long enough to see if it does the same thing. Any chance that there's just some sort of linkage issue or does this sound like for sure a dead transfer case?

Linkage would be the first thing I'd check...

You didn't say if you were running a stock set or not. If you have a body lift or a drop T-case set up linkage problems are not uncommon. Good luck.
