    Has anyone here got 4.11 Leader Gears & Quaife Diff setup for their R230 diff? If so did you do it yourself or did you get a diff specialist to do it. Not sure if I can trust a workshop to put the effort in required to set the backlash, preload and teeth engagement correctly.

    I haven't taken my spare diff apart yet but it looks like it uses a crush tube and hence doesn't require shims on the pinion gear but there's shims required on the diff sides for setting the backlash.

    I had this exact arrangement installed by Diff Technics at Kogarah, in Sydney.
    Handed them a complete used diff, Leader Gears & Quaife centre.
    One of the two output shafts will require shortening when installing the Quaife.
    They also did the removal & install in the vehicle.
    Had no issues with the workmanship or the diff.
    If you go back through past posts on Leader Gears, you'll find a number of members that had them installed were complaining of diff whine.

    Factory uses a crush tube on the pinion, you can use a crush tube with the 4.11 gears but it is more accurate to use a solid spacer and shims, but takes a fair bit more time and attention to detail to setup correctly.

    @rob260 Thanks, I've sent him a message to see where he got it setup.

    I would definitly take it to a Diff shop. And yes they will take the time to get the backlash etc correct. It would just be a heap of warranty work for them if they didn't. I installed my own Nismo LSD, but that was with factory gears and the backlash and engagement was all correct thankfully!
