4 wheel Low, but no high in 87 Chevy - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey everyone, i have been shopping for a while for a winter truck and i happened upon a friend who knew someone with and 87 chevy for sale. I went and looked at it and couldn't pass up the truck. He said the 4 wheel drive works, and I can't seem to get it into 4 wheel hi. It seems to go right into 4 wheel low, but i don't get anything in 4 wheel high. Anyone have any suggestions as to what the problem might be? I bought it for the snow, and well its not very helpful without 4 wheel drive. lol.

Linkage is probly bound up on it. Kinda weird that it goes in low but not high....

I was thinking linkage too, maybe a bad shift fork?

First, does it work in 2 high? does it go in to neutral? I couldn't get mine into 4 low and it was linkage frozen up. Does the indicator move to 4 high or does it seem to get stuck at 2 high? jim

thanks for all the quick answers. yes it does go into 2 high, and yes it will go into neutral. as i pull the lever back it goes all the way to 4 high, but once i let go and move the truck the lever seems to slip forward out of position towards 2 high. Its very odd, the 4 wheel drive was working on Saturday when i picked the truck up. When i go to 4 low, you can hear a slight gear grind and it goes right in and works in 4 low, but nothing at all in 4 high.

could be the shifter lever not locking into place... have yyou tried holding it there while it ingages?

You have answered your own question. Adjust the shift linkage and you should be just fine. jim
