Powdercoating a diff... ?
I am about to send my diff for sandblasting and then powdercoat it. OK, OK, i will drain the oil from it. But is there any danger regards to tight
tolerances of gears and bearings that should make me to avoid putting it to the oven and baking it to 400 degrees F?

I wouldn't do it, the grit gets everywhere, and could get past the oil seals... The powder coater would have to mask off the seals too,
can't see 400 degs doing them much good either....

i would say so, yes. things expand when heated, i think it could do damage to the bearings. assuming things will contract when they cool down it could
be fine, but i really wouldn't do it

The oil seals wont like it.
Get it sprayed, it will look just as good but with out the risk of damage.

Could you post a pic of your painted diff?
I would not recommend welding anything on the diff's case. You just don't know the alloy of the case and you will not be sure you have a
strong weld.

was thinking of doing something aesthetic to my diff too... just wondering, how difficult is to dismantle the diff and then put it back together after
something like IDONTBELIEVEIT has done?
We gain knowledge faster than we do wisdom!
Life is not a journey to the grave with the intention of arriving safely in a pretty and well-preserved body, but rather to skid in
sideways, thoroughly used, totally worn out and loudly proclaiming... "f*ck, what a trip!"
