Have you guys tried the following yet?? (I havent read a lot of pages back so if its been said before I'm wasting your time). I learned this in 1/12th where a diff is more important than in a Touring car.
With Ceramic diff balls the problem is the the balls are too hard to grip on the diff plates. The following instructions will make you be able to use them without having to tightening your diff a lot.
- Take the diff apart and put a heavy cutting (Low grid polish or something like that, I use a paint cutter compound) material on the balls instead of grease.
- Put the diff back together and very slightly tighten it.
- Then start turning the diff by hand every way you want. This will sound awful while you do it and it will feel as if you are scratching the rings.
- Do this untill you feel the compound is gone, refill the diff with it and do it again. do it for 15-20 minutes or so (while watching TV,... whatever).
-After this take it apart and check the rings, you will see that you have cut a really nice groove in which the diff balls will run, this is what you want because you have more ring- material touching the diff balls.
- Clean everything very good! make sure every bit of cutting coumpound is out of the diff and lube as you would do with a normal diff. You will notice you need to put very little pressure to make the balls grip enough to drive with and the diff is silky smooth (just saw the Zohan Movie
I've been driving Mod with the BD for 3 years now and I have 2 diffs that I interchange every 2-3 months or so, I have yet to put in my first new pair of diff rings, the grooves will stay in perfect shape.
Now, ONLY DO THIS WITH CERAMIC BALLS the cutting coumpound will do nothing to the balls! but dont try it with carbide or steel ones cause this will destroy them.
Oh yeah, I also ca- glue my diff plates to the outputs.
Anyone do this besides me
I know in 1/12th there's a bunch of us doing it.
