Hey guys, I have an 87 high sierra with stock diffs. When I put the truck in 4wd, the front passenger tire locks up after about 2 feet and will not turn. It doesn't make a difference in hi or low. Figuring it was the auto locking hubs, I replaced them with some new manual hubs. Still the same issue. If I put it in 4wd and don't lock the hubs, the wheels spin freely which makes me assume that the t-case is fine. I have no issues in 2wd and I hear no sounds from the t-case. I have no brake issues either. Any opinions would be great. I'm going on my second winter with no 4wd and the tires are getting a little tired of spinning.
Thanks.
Thanks.
