This was explained in my first post, and a couple other responses. Did you even read any?

maybe it's just worn out. Mine didn't act very posi before I had the rear end rebuilt recently.

GM had the gov-lok differential. Needed a set amount of slippage before it would lock. So far as I know, GM was the only ones that used such a silly system. (it would POUND when it locked...... so a lot of those that turned themselves into grenades.....)
More often than not, the wheel-spinning trick on jackstands will tell the tale. You can leave rubber with both tires even with an open differential, if both tires have equal traction, and you apply enough power, both will break loose. Once loose, it's easy to keep them both spinning.

That was my lame attempt at humor, referring to when i smoked my mal-adjusted clutch trying to get rubber on dry pavement with 33's.

not lame. I didn't notice you said both wheels didn't spin. I was being lame.

I know with my camaro you had a friend hold the wheel that you weren't spinning and it would be VERY hard for him to keep it from moving. If it were easy to keep it steady, it is an open diff.
That is how you tell.

I read every post. Some say jack it up and spin the tires by had others say it doesn't work. I'll check that little tag. I wasn't running friction modifier in my diff for years. Ooops. Also when I power brake my tires to " dig um in " at the beach only one tire spins.
