Pulsation in steering wheel caused by power steering pump or rack?

Hi,

I've developed a noticeable pulsing in my 1988 Accord steering wheel at
very low speeds, getting a little faster as I speed up, and going away
altogether above say 40 mph. I'll take the PS belt off this weekend and
see whether it goes away.

If it does, anyone know know how to tell if the problem is with the PS
pump or the valving at the rack?

Thanks,

JB

Bet one or more of your tires is out of round/true, or is installed
badly.

A wobble at low speed is a certain sign of that.

Yep, front tire finally went flat, just as I was preparing to switch it
to the rear, and showed several deep cuts at tread inner edge. Wobble
gone.
