I have a little 4 lb slapjack for pulling dents but I needed to remove an axle bearing from a Masda pickup rear end.
My solution was to use my very old internal bearing puller and the slapjack the only thing was the hammer has a 1/2 13 thread while the puller uses a 5/8 1. I removed the push shaft from the puller then welded a pair of 1/2 13 nuts to a 5/8 11 bolt
After welding 2 nuts together I ran a tap through them to make sure of no conflicting threads
then welded the nuts to the bolt I ground it just enough to remove sharp edges
