Proper alignment is CRITICAL.
Bearing is not as thick as the old bearing. Check for alignment of Belt on all pulleys. You cannot use the spinner washer ,as it is not compatible, you must use extra washers , because the BOLT is longer ,for the thicker bearing .ALIGNMENT IS CRITICAL. Also the bolt is ,LEFT HAND THREADS. The ease of installation is a nightmare, for alignment. I might just return this ,and purchase a complete belt tensioner/with a pulley , just for O.E.M. specifications and alignment.
