If you have a press that would be the best method for replacing a bearing. If not, this method will work for you.
This procedure will work on any style pulley. Aftermarket or stock pulley. I'd be careful with double bearing pulley's though.
Replacing a $10 bearing is a lot better than replacing a $80 pulley IMO.
Stock pulley from the front:
Stock pulley from the back:
You want to find a socket that will just fit through the opening in the pulley: (15/16th impact works perfect):
Use a hammer and drive the bearing out of the pulley:
Napa part number for the replacement bearing:
Same size bearing:
Place the pulley on a rag and set the new bearing down in the hole:
DO NOT DRIVE THE NEW BEARING IN DIRECTLY WITH A HAMMER!!!
Use the old bearing to drive the new bearing into place:
Use a large enough socket to drive both of the bearings (1 1/8th):
Good as new:
