Lisle 58430 Shaft-In Seal Puller for Cam, Crank and Output Shaft Seals

This is the tool for the seals you cannot get a screwdriver behind because the shaft is still running through them. The adjustable hook slips behind the lip of the seal, the push rod braces against the case or the engine, and you lever the handle to walk the seal straight out. Because it pulls against the seal and not the shaft, you are not prying on the sealing surface and leaving a burr that will chew up the new seal the day you install it.

On the bench it earns its keep on any seal that sits around a shaft that is not coming out first: front crankshaft and camshaft seals during a timing belt or timing cover job, and the extension-housing or output-shaft seal on an automatic where you do not want to drop the tailshaft just to change a leaking seal. The hook is adjustable so you can reach shallow import seals as well as deeper domestic ones, and the tool comes with a spare hook blade.

The right way to use it is patience: get the hook fully seated behind the metal case of the seal before you load the handle, and brace the push rod on something solid so all of your force goes into pulling and none into slipping. This is a small-seal, shaft-in-place tool. For a large wheel or axle seal with open room around the shaft, a slide-hammer seal puller is the better call. For the tight ones where nothing else fits, this is what techs reach for.
