grinding in transfer case

Hello, I have an 83 F250. Not all the time, but a lot of the time my transfer case makes a grinding noise. It happens whenever I move it, either from 2 to 4 lo, or 4lo to 4hi. It dosn't matter. I always have to cut my truck off and change then turn it back on. It could be, I'm doing something wrong. I usually just put it in nuetral then put it down into 4 wheel drive, then get out and lock the hubs. but if there is another way i should be doing it , please tell me. thanks for the help

Even when the transmission is in neutral it will still turn. So when you shift the T-case and if you leave it in the neutral position for too long it will start to spin too. If this is the problem just getting it down into 4-lo a little quicker should do the trick. Good luck with it!

If your F250 has an NP-208 I would bet that your RANGE Fork and your SHIFT fork are both worn.

With the NP-208 you can Shift on the fly from 2H to 4H. Ford instructs you to STOP the vehicle, put Tranny in neutral and then shift into 4L.

I had my NP-208 rebuilt in my 1984 Bronco. I was slipping into neutral every 2-3 miles.

How many miles on your truck? Good Luck! Keep us informed..
