^ since he is lowered alot he may have altered the angle of the how the endlinks are positioned and therefore no noise is caused.
I have the FRPP kit and it made a lot of noise.
I ended up getting new joints that were teflon coated to be tighter and they were great but the noise came back. After further investigation it was determined that the endlinks need to be as straight as possible vertically.
I added some spacers and now all is good.
