89 K5 NP208 slips out of 4 wheel drive

[Defiant]

I need to fix this asap. I noticed last weekend on a hunt that when I am NOT under a load (coasting down a hill) the four wheel drive slips back to 2 wheel drive. This happens both in 4H and 4L! I just had the 700R4 and the NP208 gone through. I am hoping this is just a linkage adjustment. Help me out guys.
Thanks
Larry

Check the linkage.

This usually happens when the plastic pads on the shift fork go bad.

yup, i have the same problem. Quick cheap fix: Bungee cord. More permanant fix: rebuild the case. or buy a rebuilt

Thats funny I thought I was the only one with a bungee corded 208

Run a cable insted of linkage. Had that problem with my last k25 diesel. Now have a k5 build from the ground up. Cable is the only way not to transmit body movement through the linkage.

I also had the same problem on my 91 jimmy. It has the 241, but i imagine the linkage is the same. I solved the problem by rebuilding the t-case. But i also did readjust the linkage at the same time. Its been good ever since.

I ran mine like this for a while... when I took apart the case, the range fork was all cut up and metal fragments were everywhere. Needs new plastic pads and possibly a new fork asap.

Check linkage and TAKE THE TRANNY MOUNT OUT AND INSPECT IT. I just upgraed to a 241 from a 208 because of it popping out of 4WD high... tranny mount looked OK... untill I had it out to swap cases! Oh well.

Cable is the only way not to transmit body movement through the linkage.

Yeah kind of... my new shift linkage on the clocked 241 has a tiny heim joint on both ends... Unless my drivetrain shifts forward and back on the chassis pretty good (hope not), there won't be any transfer to the shifter.
