I had a constant squeaky noise issue on the drivers side spring when I first had mine done. Ramsey thought they had it figured out but they didn't. I drove it home anyway and Ramsey sent me a whole new set of springs. Thinking there was maybe something wrong with the spring, I had one of the new ones installed on the drivers side only. The constant noise went away, only to be replaced by a noise when the spring is under compression. I have about 30k miles on the conversion and other than the noise have not had any issues.
