ok - I am still new and learning about these trucks. I wanted to ask about what servicing involves. How do I service my diffs? What oil do I use? Hell - what do I do? I also understand that I need to screw tight a few screws when I get it Monday. Especially the steering arm screw that Afro Samurai pointed out in his thread. Not on the servo but the next one on the arm.any other screws to tighten? What should I lock tite? I am also planning on replacing the servo day one. It comes with these little rubber square things - I need to put them in to reduce vibration right? Sorry for all the questions guys but I know very little and want to take care of this one and make it last.
