2001 Accord Coupe - 4 clyndr - manual trans.

Replaced the Power Steering pump with a remanufactored Honda pump, new
belt and HONDA PS fluid. Tensioned the belt the best I can. Now
getting a loud vibration/noise from the pump area. The pump turns
freely and doesn't make any noise. Tighened everything down. Noise
gets worse when turning the steering wheel. The pump is moving the
fluid and the reserve is up the the upper limit line.

Any ideas?

Thanks.
