I have a new project SRlll with a LS 3 and the power steering is noisy "until" I put a load on it
Everything is new and I have a hydro boost unit and when I put pressure on the brakes or the steering the noise will go away for a moment.
I have blead the unit several times with the front wheels off the ground and turned left and right to expel the air.
This has not corrected the noise, the belt does not seem to be slipping as it is not squealing I have had lose belts before, and it does not make that noise

Thanks
