LJDB 103 Posted July 26, 2016 Hi guys, I recently got my hands on a super cheap BA mk2 XR8 and the diffs very noisy. I was contemplating just putting new bearing in and away I go BUT while im in there I might as well do a Ratio change to help the 260 out down low. The M86 seems pretty expensive $500-600 for gears $200 for bearings and $200 to replace the clutches in the centre and that's me doing which I've never opened up a M86. Can I for example grab a Au/BA standard ute diff, set of gears and Re shim LSD centre or even grab another locker type center to suit and put it in without dramas? Ba ute diffs seem to always be noisy so I'm sure people have swapped them around before. Share this post Link to post Share on other sites
gerg 10,871 Posted July 27, 2016 Always the carrier bearings in them, if not axle bearings. Only seem to be BA onwards. I reckon it's the factory preload, they must have bumped it up in anticipation for the amount of power and weight of the vehicle. Synthetic oil helps keep it all cool but they still fail eventually. Salisbury-type diffs just aren't up to it in my opinion. Sent from my iPhone using Tapatalk Share this post Link to post Share on other sites
