The diff nut clamp replaces the M3 nyloc diff tension nut. This allows the diff tension to be adjusted
by removing only the right hand wheel.
Adjustment is then achieved by simply loosening the locking grub screw and holding the 1.5mm driver in place at the same time as turning the left wheel/other side of the diff.
Finally, tighten the locking grub screw and put the wheel back on.
