Review on OTC 4520 Differential Bearing Puller by Brett Gilbert

I used this to pull out the side bearings on an 8.8" Ford Traction Lok and it worked great. I was concerned about some bad reviews but my experience was positive. tried pulling the bearings off on one of these, know the area for the shafts is narrow and flat, very narrow. I have several 2-jaw pullers and none fit. This fits without altering or grinding the shanks. I would also like to note that the puller did not touch the bearing race, the bearing was not damaged and could be reused. Although it was a one-time use, I'm very satisfied for the time being.
