Started my build last night and things were just not feeling right!i am used to 2wd trannies that spin very freely. Some guys at local track say a 4wd feels tighter but mine feels to tight. Should you use the set screws in all cvas?i had two that with the screws in they were binding others smoothe.
Directions don't show installing set screws but they come in the bag.

Any help will be greatly appreciated!

My diffs feel. Good, I used the 6&3 spacers but main cvas still feel tight where it comes out of gear box..
