Rearend Whine after rebuild???

[tcrist]

The quality of parts these days really gets me and then the idea of, it whines and will always whine, so live with it, does also.

If you bought a brand new pickup and the rear end whined, would you not take it back? Or not buy it!!!

Those have brand new gears in them also.

It used to be that you bought a gear set that was matched and you know what, it did not whine. That was the reason that you bought a MATCHED gear set.

Sorry, off my rant.

I agree 100%! Im not sure if it has to do with offshore steel, gear cutting, or what. Have read that alot of this is due to trying to make the rearend stronger and last longer gives the resulting whine.

Hopefully when the gears wear in and polish themselves up it will be good. After 500 mile inspection on first gear set you could still see tool marks, gears had yet to wear into polished pattern, which means this steel is very very very very hard. (Im gonna say that OEM is somwhat softer) Shop replaced all bearings and a new gear set with a little better results. BL was set to 11/1000. Ive been into every part of cars and trucks by myself for many years but this is the first rearend, and thanks to all you guys I am learning alot.

thanks!

After all this talk about rear axle whine I thought you guys might enjoy some "science" from one of the OEMs...

We ended up using them on some C/K's (I think) and Astro/Safari (I'm sure).

Some time I'll have to tell you about tuning those.

Astro or Safari??? Why tell us about those? If I owned one I would be ashamed to be seen in public. I might even slit my wrists.
