People swear by schumacher diff lube and associated black grease and is what i tend to use. The main thing to made it smooth clean and keep everything flush and renew parts regularly. I tend to use carbide balls aswell theyre a bit harder and last longer than my kit xray ones.
You can also use a shock foam inside the outdrive which does help keep dirt out of the thrust lengthens the time of rebuilding the diff again.
I did use a tutorial from radio race car magazine where they did a step by step guide to building a diff was really handy. Think it went as far as having a slave motor attached to bed it in  bit ott to be honest. |
Just to clear something up...
Diff plates are ground... You'll never get them "flatter" with wet n dry, all you'll do is make them worse.
