Axle cheat sheet

[zoom zoom]

For anyone interested & for future reference, I took some measurements with my xr2 axel and rio axel, and this is what I came up with.

Measurements were taken from the where the seal on the transmission would be, out to the seal on the hub, with both axels COMPLETELY compressed and straight. For the measurements above to be right, they measured from tip to tip, from the extreme ends of the axels, completely compressed.

They're also the same thickness. The Rio axel looked thicker, but it's not, I think they were 7/8" thick but don't quote me on that. Both are 26 spline inner/24 spline outter

Auto Festiva/Aspire is different, right? 20 spline inner ends?

Yes I suppose I could add that they are 20/24.Wouldnt hurt,especially when doing an F series.

Pretty nice, so I understand it, on the festiva stats...

the 18/24 18 is inner (diff) splines, and the 24 is the outter (hub) splines?

Left is total axel length for driver side axel, and right is total axel length for pass. Side?

And total length is overall from hub spline to hub spline attached to the transmission?

If that's right then the track width could be from the center of the tire to center of the tire, and adjusted with wheel spacers, or rim offset?



How much total length difference would it take to bind the cv joints or cause problems, say I wanted to swap the rio transmission and axels into my aspire..?

You are correct on all accounts except that the measurements are always taken when the axle's are compressed. And that measurement is from the outside tip to the ridge near the seal. If you measure all axles this way (this is the industry standard) you can then compare them all. I too was wondering about the Rio tranny and axles.This was one of the reasons I did the sheet. Not to mention I can be Rtarded when reading sentences that contain measurements.Its much easier for me when I can see numbers in spreadsheet form. Weird I know.

you might have 5/8" (per side) of compression to play with before you have binding, when installed, a typical axle is only 1/2" away from the trypot base. i wouldn't push the issue too much though as the binding can cause output shaft bearing wear.

I have a hard time processing info,spread sheets help me.So I made this,hope maybe it can help someone else. I made a couple observations:
Using a 02 Rio knuckle on a Festy,appears to require lengthening the Tie Rod @ 1" total.Using a Rio knuckle on a Aspire is almost identical as far as width goes.
Rio's track width compared to Aspire's are 1/16" wider.But use axles that are 1/8" shorter.So are they changing track width via rim backspace? How is track width measured? From outside edge of rim,or center line of rim?
F series tranny in Aspire, you can use na Capri axles with only 1/16" difference in axle overall axle width.


Anyone know the track width for the na Capri?
