Power Steering issues

I suspect 2 separate problems.

I have a '97 850 wagon with 110K on it and had noises but pulsing in the wheel when I made hard turns. After inspecting, I found slight leakage on the rack, so I replaced and the problem was gone.

On your wheel shimmy, if you feel it in the steering wheel that's good indicator it's in the front end. Who did your wheel balance? You might just swap the tires front to back and see if the shimmy moves from being felt in the wheel to being felt in the floor or your seat, then it was probably still a wheel balance problem (eg out of balance, bent wheel, etc).

Thanks for the reply, I'll switch the tires around and see if that takes care of it. I'm 99% sure that if it were a wheel balance/bent rim issue, that its the front left tire. I got the balancing done at crappy tire here in canada, I didn't think that it'd be possible to screw up something as trivial as wheel balancing.. Hopefully I'm mistaken, and it turns out they're just morons that can't balance a wheel.. I'd much rather be out the $50 for the crappy balance job (did all 4 wheels) than to find out I completely wrecked my front end!

Thanks Ben
