Will this be a problem? Gear question
some guy is selling some gears real cheap. the ring gear is perfect but the pinion is what worries me. it seems the outer bearing seized and scratched the surface on the pinion a little bit. will this cause any problems? is this pinion usable?

They would have to be dirt cheap for me to bite, $50-$60--explain to the fellow selling them that they are at best a "pig-in-a-poke".
That said, when installing them use Loctite 603 bearing retainer on the pinion shaft and the bearing's inner race. Degrease the pinion shaft and bore of the inner race thoroughly, apply the 603, and assemble and adjust the pinion preload somewhat quickly (in less than 10 minutes) and there's a better than 99.44% chance it will be fine.
One other comment, a good machine shop could lightly knurl the shaft to provide a better fit for the bearing if needed...

I know this one but can't to save my own life recall the name - a blonde right? I think the Ivory "Snow" stuff was still a couple years before my time (33, btw) but I know what stuff you're talking about, think it was a laundry detergent if I'm not mistaken.

Yeah i wasn't going to buy them (already have 4.10s). It was just that the pinion caught my interest and thought i would ask. I would assume that that pinion would cause some noise problems. What would cause this damage though? Improper installation?
