So the dust boot on my rear upper control arm is torn. I then bought a replacement from a junk yard on Ebay, and that as well was torn. I took a close look on the dust boot and its not permanently on the control arm itself, it is held on there with a spring or some sort. I was thinking of just replacing the dust boot on it, but im not too sure if its replaceable. I want to know if anybody else has done this because Im not trying to cash out on a new RUCA.
