My converted CRT

[Jammin]

About the set screw deal. You mean the set screw on the actual rear diff? What do those do, cause I see one on the center diff too. Sorry about the questions, I'm new to truggys. And thanks a million for the help, gotta get my truck running like yours.

Take a close look at your rear diff, where the rear center drive shaft connect on the rear diff. You have the outdrive how slide on the rear diff input pinion shaft. This outdrive is secure with a little allen screw. This allen screw must be tighten up with good locktite on it.
