Hey guys,

Just got in some new axles and a diff from GBR. RD76 30 spline ARB, and the MaxiDrive 30 Spline rear axles. I did some measuring with the calipers if anyone is interested:

Diameter of Diff end splines:

OEM 1.235 (inches)
Ashcroft 24 spline 1.235
MaxiDrive 30 spline 1.305

Minimum Diameter on axle shaft:

OEM 1.068
Ashcroft 1.125
MaxiDrive 30's 1.225

Diameter of oil seal surface:

OEM 1.257
Ashcroft 1.26
MaxiDrive 1.26

I looked closely at the axles and notice that the Maxi's maintain a more constant diameter throughout (less necking up and down like the Ashcrofts and OEMs).

The 30 spline axles will NOT fit in a stock RD56 housing with 30 spline side gears. They are too big to fit inside the outer bearing mount, although this could be machined out.

I will include a bunch of picts when full service is restored.

The air collar on the end fit very tightly to the 2 O-rings when i did some. Be careful when installing, it's easy to ruin the o rings.

Here are the picts. And btw, they will not fit in the stub axles without machining out about 20 thousands.

ps. the axles are 30 spline,ashcroft, OEM from left to right
