Yikes: Wheel Bearing Puller Kit $386!

[Frederick Smith]

The center screw on the Schley has a thread that can't stand-up to the
use of air tools. The Hub Shark has a more robust screw, more like an acme 
thread and works fine with impact guns. Of course....I own the Schley 8-[
It's more of a work-out, but really not that bad. I use a 1/2" drive x 24" 
breaker bar and a geared ratcheting head. Fairly easy with that set-up.
