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:

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:
