Lisle 56750 Seal Puller. For Oil and Grease Seals. Simply insert the tip of the tool behind the oil or grease seal, press and pull. Leverage works for you. Two size tips reach in and fit nearly all seal applications.
I used the tool to remove front and rear Model A Ford wheel bearing seals. The negative aspect of this design is that while you are pulling up on one part of the seal you are pushing down on the other side with the heel of the tool. A slide hammer with a hook may work better.
