Default Sierra Diff pre-load + Backlash

Hi all,

The pinion bearings are shot in the diff in my dad's kitcar....

Does anybody know what the pinion bearing preload and CWP backlash should be on a standard sierra 7" open diff ?

Thanks in advance

Pete,

Although this refers to the scorpio, the procedures are identical...

something doest quite add up with that Scorpio spec
it says set the backlash to 0.01mm
then tighten the bearing 4 notches where 4 notches = 0.16mm, in other words remove all the backlash and set it under load
Where am I misinterpreting this, its been a long day at work
