Thanks for the reply.

Good advice there, taking care of the known issues first.

Hopefully this weekend I'll get a chance to deal with the rears.

After more driving and thought on the subject, I'm thinking/hoping that it's just an alignment issue and that for whatever reason when I accelerate, the shift in weight from front to rear is what causes the difference.
Yesterday I floored it up to about 6k in 2nd at one point and the steering doesn't seem to get worse with the rise in speed or rpms. I would assume that if it was something more serious, such as the differential or a wheel bearing, etc., that I would notice a difference at full throttle or increased speed.

I'm thinking maybe fixing the front calipers (no more dragging, or at least far less) is what caused this to show up. I noticed that of the times I checked the rotors and noticed they were hot when they shouldn't have been, that the passenger side was hotter, at least most times. Hopefully that was partially canceling out the bad alignment, and that's all that's wrong :shrug:
