Question about a big Bronco T-case

[jeff68]

Hey Guys,<br>I know this is mostly early Bronco's, but my Nephew has a '79 with an auto trans, and I think an NP205 T-case (sound right on this T-case?), when he gets it in a bind it jumps out of four wheel drive.<br>What causes it to jump out of four wheel drive?<br>If anyone can help solve this problem it would be greatly appreciated,<br>Thanks, Jeff

If it is a part time case (4H-2H-N-4L), then it is a NP 205.<br>I would first check the linkage and ensure it is tight and allowing full engagement. If it is, then it is an internal problem and would require a teardown. Could possibly be bent or worn shift fork. 205s are very stout so I would suspect the linkage...

Thanks 4byford,<br>He told me there didn't seem to be any adjustment as far as he could see, but all this has been out of the truck lately, even the engine has been rebuilt.<br>I'll try and work with him a little and see if we can determine if it is shifting all the way or if there may be a little adjusting needed, I hope that the T-case isn't damaged.<br>Thanks Again, Jeff<br>
