i was wondering if any one has ever greased the the front diff up in there maxx. What i want to know is if you pack it up till it cant hold anymore greas in the front will it grab more then the rear diff cause i might try it out and see what happens some in put would be great.

Using something like diff lok or silly putty, yes, you could notice a difference in the diff action. Regular grease - I doubt it.

is diff lok a hobby brand or what
