My BMR Trak Pak is making noises, I realize that additional road noise is to be expected with such a rigid part replacement, but can I minimize it somehow?
Yes, you can! General Motors’ original design utilized a neutral pinion angle of 0 to +1 degree. Any alteration to this causes slight binding from other components that makes for a “creaking” and sometimes “clunking” suspension. While a negative pinion angle(pinion down) may be great for the drag strip, try to keep your settings as close to neutral as possible for daily driving. This will minimize noise as well as premature u-joint wear.
