High Pitched Noise

I've recently developed a noise in my 88 325i, I noticed it after I took the car to a Car-wash where I used the spray wand, co-incidence I believe ?
At about 15-20 mph I'll hear a high pitched whine coming from the left rear wheel hub, goes away when you slow to 20 or so. Friends and I isolated the noise while the car was on a lift with the wheel off, the noise sounds like it is coming in contact with rubber. I took off the axle nut, pushed the axle in a bit, to lube behind the hub thinking that would alleviate the issue, not so. Any thoughts as to what is causing the noise. Auto tranny fyi
