ok I got ya. What I was saying is that it is much quicker setting pinion bearing preload with a pipe wrench since it can be removed much quicker than a pinion holding tool. Odds are, you are going to have to remove the yoke more than a few times to get the correct shim pack for get the preload in specs and it would get old removing that pinion holding tool after a few times. I realize that the yoke holding tool can be used just to remove and install pinion nut and that's obviously what you are getting at and if that's the case, buying an occasional use "specialty tool" doesn't make much sense unless you are going to use it more than a few times a year. There are some specialty tools worth having but this isn't one of them IMO.
