axle question

[denn454]

transmissions, axle, close enough. anyways, i was putting in my new posi yesterday and ond of the axles is really showing lots of wear. would 87 montecarlo ss axles work? I have a set in the garage, they have different numbers but appear to be the same. will they work or what should i measure to compare? thanks for the help.

A Monte SS will have the 7.5 rear and 26 spline axle shafts. The 8.5 in the 84-87 Turbo Buicks has 28 splines.

WHERE IS THE WEAR?IF ITS AT THE OUTER BEARING SURFACE THERE ARE OVERSIZE BEARINGS AVAILABLE FROM THE LOCAL PARTS STORE.SOME GOOD MACHINE SHOPS WELD EM UP AND TURN THEM BACK DOWN TO THE CORRECT SIZE.IF YOU CANT FIND THEM YOU CAN TRY NATIONAL DRIVETRAIN IN CHICAGO.

its on the very end where the axle rides. i have a set of bearings for it, but i want to wait untill i have a good axle to put them on with. I'm almost sure that the monte axles are 28 spline, i'l count them again, and i know it is a 7.5 but does that make a difference?

THEY WONT ENGAGE THE SIDE GEARS.
