Groaning Sound from left side when I accelerate?

Bad CV shaft, bad bearing, or maybe the brake rotor warped or other? I would carefully inspect them all. I had one set of aftermarket front pads on my taurus that were made so the hung over the outside of the rotor. As they wore, they wore a lip in the edge of the pad and caused some strange vibration/noise.

I also had a bubble in a tire once that cause some strange noise at higher speeds.

i have had pres. side hose vibr. and return hose vibr. on many different car models. being yours is on a taurus i would first wonder if it has been replaced for leakage (common) and not routed perfect....if it is routed correctly and not grounding anywhere i would try to isolate the noise by using a piece of ROPE to put some tension on the hose assy. and seeing if it changed the sound any at all. if the noise is any different or gone than it is a hose/line prob. if noise doesnt change than either it is an internal pump prob. or not p/s related.........all these ideas are 'probably' b/c its very difficult to diag. car noises on a keyboard and monitor but you can get some ideas..............kjun
