help with fourlink measurements

it shouldnt be your pinion angle if you got an over the axle setup...the pinion angle shouldnt change any when your bags inflate and deflate. if the pinion angle was off you would hear it all the time. on a cantilever setup the rearend rolls forward slightly when the bags are inflated, and rolls backward when deflated. but thats cuz the bags are mounted on the bars. you said up above its because of your small c-notch...maybe thats it. when its all the way down it could be notchin out and rubbin on the bottom of the notch.

yeah when i get the money, im going to get sd.com's 10" notch after new years and all that so i figured it was the notch cause when its deflated the rear end has no suspension so i figured when id hit a bump or something itd grind
