Removing a press-fit shaft seal without scratching the metal housing can be difficult. A seal puller makes this easy. It features a dual-hooked head on a steel shaft with a plastic handle. You slide one hook behind the rubber lip of the seal, rest the curved foot against the housing, and pry. The leverage pops the seal right out. Never use a screwdriver for this. Screwdrivers slip and scratch the aluminum shaft or bore, causing permanent oil leaks.
