Nice build man!
I never had a squeak with the RCV's, but from Day 1 they click when I go full lock to full lock....sounds like a CV going bad on a "normal car".
I called RCV about it, they said not to worry about it, and if it bothered me to "send them in and we'll adjust them".
I have no idea what they could do to "adjust them", but this is my DD, and between the shipping time & the inconvenience, I've just kept them the way they are.
The noises haven't gotten worse (been about a year since the install).
