While accelerate noise is coming from my steering pump

Rubbing noise in suspension while turning at low speed. Maybe in the steering wheel, but hard to pinpoint. Replaced ball joints, swing arms, intermediate steering shaft, tie rods, struts and shocks (coil overs). Was needed, not just throwing parts. Lubed thru floor rubber bushing to rack and pinion. Disassembled steering wheel but couldn't isolate noise or get to steering wheel bearing. Noise disappears when front end on jack stands. Driving we crazy...
