Howdy all (and Happy New Year). I've got some rear wheel bearings going out, so I've got the Z1 replacement kit (370z/G37 axle/hub combo) on the way. Axle alone seems super simple (axle nut and unbolt from differential), and hub just seems like a few extra bolts (although apparently you need an air chisel? Mine is fairly free of rust so I'd hope it could come out without one).

Additionally, I recall the infamous axle click TSB calling for copper grease, but IIRC the Nissan stuff is stupid expensive for how much you get; any third party substitutes? From what I remember, you apply the grease to the axle splines into the differential, but I haven't seen anyone put it on the axle-to-hub spline as well; is it needed here?

Thanks for the advice!
