Hi all. Years ago I ran a supersprint with a quaife ATB in the sierra diff. Quiet, smooth and effective. Now I have just returned to the fold with a Roadsport 150 (3000m). It has the Ford open diff but is noisy as hell, clunky, lots of backlash/shunt/chatter (at lower speeds/revs). Would fitting a Quaife ATB solve any/all of these problems? Is there a better solution?
