are you talking about the diffs or the spur? To answer your question I don't hear a clicking noise. Now since you have the same setup I do (mt2 .18cvrx) I'll ask you a question do you hear a constant rattling noise coming from the clutchbell area. I always here a rattling noise and it doesn't sound good but I've ran it through over 2qts and haven't had any probs with anything, It's just a noise that doesn't sound good but doesn't appear to be causing any probs. My other question is I've read a lot of peole shimming the diffs, I don't get it what part do you shim and which way back and forth or up and down. I haven't had any probs with my diff, but when I was burning up my spurs (mesh was set wrong, my fault) I took apart the front and rear diff they both looked perfect and packed with grease. Anyways sorry I couldn't help much, but maybe you could help me.
