As you guys might know I am new to Nitro, had a competition electric a while ago. My old differential was HUGE, like over an inch tall. I saw the NEST's diff in the LHS today, TINY! Ever since I got the truck running good, it makes a metallic noise when I turn one wheel with the engine off. I tightened it pretty good, I think it could go tighter. If you go as tight as possible, it would make it almost like a solid axle right? Why don't they make these things with solid axles anyway... I mean when I am out in the loose dirt and the right tire is in softer sand, it tends to take off faster than the left and cause it to swing to the left as I punch the throttle. Is this a symptom of a loose diff?
