Pete, want to troubleshoot? Remove those two pulleys. Oil the races on both sides (soaking overnight may allow it to penetrate past the dust shields). Grease the bolt. Grease the inside face of each bearing and the spacer. Reassemble.
Did it help? How did the bearings 'feel' when you had them off the car? If this helps, buy the new pulleys and replace them when it starts making noise again.
Have you isolated it to one specific belt path yet? If so, don't replace just one. Do both pulleys on that path. Have you considered swapping idler pulleys from one spot to another? The pulleys on the tensioners are identical to the smooth pulley on that double idler.
Thanks Bill. On removing the pulleys....are they reverse threaded?
I have not run the car with only one of the belts. I will go ahead and oil them to see if it helps.
Let'* not start on noisy driving...I'm currently driving with one LOUD, but possibly two failing wheel bearings, a whiney idle and accleration that turns heads (probably due to these pulleys) and a clunky rearend because my shocks are shot!
