JSeery and Bored&Stroked have both hit the nail on the head. Proper installation won't allow that two jaw puller to work. Ultimately the axle can suffer cracking and worse in the keyway area. ( shear off hub area, loss of wheel, and hydraulic brakes ) Your choice. But it's no fun when you get bit in the ass.

I would right away search out drum retainer clips. In the event your axles have been overly stressed.

Thanks for sharing Good Luck.
