STP: LOL, I once worked for a Chevy dealership. They used to add STP to noisy differentials in the used cars. Made them quieter, that's for sure. At least until they were out the door. And, an old mechanic once told me that 'back-in-the-day' they used to mush up bananas and fill a noisy differential. He swore it kept them quiet. Now that I think about it, doesn't WD-40 sort of smell like over ripe bananas?
Wow, talk about highjacking a thread..................
I routinely found cars with the diff stiffed full of sawdust to quiet it down in Chicago...found a trans full of it once.
Couldn't believe it still moved but it did.
Pan looked like it was full of red velvet cake.
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
