Sometimes releasing the tension on a belt allows the bearings in some other part to unload and they can't re-align. Idler Pulley's have done this to me a couple times. AS well as AC compressors clutch idler bearings. Good Luck Dave __________________ Dave - PDX 1995 318ti - Active Black and Tan. 2005 330xi - Mtech 1 - 6spd - Orient Blue/Black |
