Not what I meant.. The diffs are sorted - ON THE INSIDE(and with silicone oil - not grease, which is what I'm talking about..) I mean just before putting the whole front or rear end assembly on the chassis... In the Savage instructions it's clearly stated - put grease on the OUTSIDE teeth of the main diff gear before attaching the skid plate..(and inside the cups where the bones go for that matter..)

Whatever the case, I did it on the rear, but not the front..

Only wanted to ask if this is something important enough to go take the front end off and put some grease in there...
