It should not may be a problem with the clutch packs in the posi unit..Is it a stock rear end?

as far as I know its stock, and when I get down on it, it always pulls to the left.

Mine too, until I rebuilt my transmission. I'm reasonably sure that on my car this was caused by 1) excessive play in the drivers-side rear wheel bearing, and 2) excessive play in the inboard drivers-side strut rod bushing. This play combined to throw the rear geometry off.

After the suspension rebuild, including bushings, bearings, alignment, it now pulls straight.
