    Heres me thinking they would set the CW+P up if that was the issue but they dont change anything. It's kind of gone over my head as to why they dont do that and why a new center wouldn't fix the issue but time will tell...

    Do they even make crown wheels and pinions for these diffs any more or will I be looking at a 2nd hand part if its at fault??

    $600 ! , is that to fit a Detroit type guts in your hemisphere or to fit an air locker ?

    I guess... The LR guys up here probably wouldn't even know what a salisbury is though so it would be a trip to hobart and a date with JC :P

    Its an Air locker with compressor install etc... $600 is steep but I want it done right.



    I'd look at investigating it myself or even fixing the backlash but diffs are an unknown for me, haven't had much chance to figure them out and salisbury being a different design I'm put off. Also the advice ARB gave was that fixing the backlash on the diff might well cause it to fail as its running on different faces of the CW+P?

    Mate a salisbury is just a diff. just that you set them up on your back not your feet. and there is less boults to muck about with and less lifting

    I had an ARB locker installed in my salisbury around 4 years ago, pretty much totally eliminated the backlash present.

    This is essentially what I'm hoping will occur. I think I can feel where the pinion contacts the crown wheel when turning the flange with the rear prop off and the remaining movement is post contact to a large degree. Given the flanges, axles(these are HD units), A-frame etc are all in good order I'm just left to figure the center is the culprit.

    I'll let ARB work their magic and go from there. If it needs further work then so be it, as long as the outcome is a good strong diff.

    Samblers, which Perth dealer did you use, and how much did it cost?

    One option is to take off the inspection cover and take a look. You'll soon see if there's a crownwheel backlash problem, and if it's just in the differential, you'll know the locker will fix it.

    X2.

    That would be my approach also, James.

    If the crownwheel and pinion has been running for a considerable time with excessive backlash, the only way then to set it up is to 'blue' the teeth and get the best match with the contact marks.
