from my pal with the '87 blazer:
**MYSTERY SOLVED**
Took it back to the old man who aligned it to have the alignment checked.
Alignment was dead on. The old guy already had my truck on the rack, front jacked. So I figured maybe we could look around again. As I was telling him the problem......
He went and got a wrench - took the tie rod off the right wheel..... looked at me and said,
"Ya front u-joint's junk, it's lockin' up ya wheel."
Sure enough, he moved the u-joint a bit with a big screwdriver and the wheel turned just fine. Moved it again - it locked up the wheel.
So a couple u-joints and might as well do bearings while I'm in there.
Then I can get off the Short Bus.
