When I accelerate real hard, my car veers to the left otherwise it tracks pretty straight. Anyone have this problem? I think it's attributed to the rubber bushings on the rear control arms. Maybe time to think about swapping them with urethane.

This will also happen if the steering wheel is turned slightly to the left during hard acceleration.

Life is tough, but it's tougher when you're stupid...John Wayne.
Si vis pacem, para bellum.
But not to be confused with Bump Steer which can occur while turning the wheel to the right or left and hitting a bump. This phenomina also increases in severity with speed and during acceleration.
One can also confuse this with a Caster lead...as when the car is set for driving on a crowned street or highway and then is taken to a strip or track and pulls left becaause of the caster lead.
It's not torque steer. Torque steer occurs on FWD cars because of there being caster on the driven wheels.
If your car pulls hard under acceleration, and you know it's not the road surface that's doing it, you have one of two problems. Either one of your tires is soft, or one of your rear control arm bushines is soft.

Must have something wrong somewhere! Every time I get an alignment and get on it hard the car starts tracking funny. Take it back to Sears and have them re-check the alignment and it will have some off the wall toe setting on the right rear. But I can't for the life of me find anything loose or worn!

I aggree 100%. Drive my wife's Acura CL Type S (automatic) and when you hit second at WOT the steering wheel will almost snatch out of your hand. Don't be on a cell phone (I never drive and use cell phone) and and forget that you are driving it and pass someone on the floor because it will wake you up.
Your problem sounds like alignment (not just slight) or tires pressure.
What you describe is what I've felt from brand new with my 02 Z.
I feels like the Right rear thrust angle is rotating and steering the ass towards the right.
As soon as I lift throttle it snaps back in line. Mind you this is only very slight and I attributed it to stock rear tierod ends and A arm bushings.
DJWorm makes an interesting point with drivetrain mounts, but I cannot see how it can translate into direction change unless it's warping the rear subframe. Could you provide more insight?

This is what I thought too - torque steer only occurs on fwd vehicles.

Ummm... Sears? Perhaps that's the problem right there!
Years ago, I had a Datsun 260Z (a car I loved, sniff, sniff). One of the bushings on the right rear lower control arm disintigrated. It was a sleeved bushing, the rubber between the sleeve and casing rotted. But I digress. When you got on the throttle, the driven wheel would compress the what was left of the bearing, cock the A-frame, and the car would steer to the side. When you came off the gas it would come back in line.
An extreme example, but it illustrates the point. Bushings compress under load and the alignment changes.

Kind of what I was thinking. Another scenario...one wheel applies more torque due to the posi slipping? The amount of torque these engine put down would definitely have an impact if one wheels was being driven more than the other, causing the A arm bushings to compress more on one side. I think it would only takes a couple of tenths of a degree to make the car track steer.
Does this make sense?
As far as Sears doing the alignment, the guy who does the work is very conscientious and always let's me get in there and look things over as he's doing the work. He also gives me a print out and we go over the specs after he's finished. The alignment machine he uses is a new Hunter, so you can't go wrong there.
