Jim, I have a "Snap-On" like this, and have used it for many years with no
problems. Of course it cost four times as much. "HB" also offers a second
"hook type" design for about the same $$$, the only thing I have seen the
second type break the tip on tough seals.

One thing, you need to use caution not to damage the opening where the seal
seats or the actual sealing surface on the shaft, as oil will escape from
behind the seal. A light coat of sealer on the outside of the new seal, plus
a light coat of oil on the shaft is a good idea.
