Axle cheat sheet

[nitrofarm]

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?

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 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.

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

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.

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

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

Oil pan clearance aside, the rio axle eliminates the need for that inter shaft. Right?

Oh yea, that chart should be stickied.

[nonamekid]

That chart is not completely correct. The festiva and aspire inboard spine count is 22 and the NA capri is 24. It is mostly just a repeat of what is already in the sticky on transmission swaps, just adds the 01-02 kia rio axle lengths, and some track widths.

The comparison of the total length can be deceiving as it doesn't take into consideration the difference widths of the differential between the E, F, and G series transmission. I am assuming there is a slight difference based on a few reasons; it just has never been verified.

The ball plunge type like the festy has 1 7/8 inch CV travel, The tripod type has 2 1/2 inch of CV travel, This makes a big difference to us lifted and long travel front suspension Guys...

Yes I would like to correct, but I need a mods help. And yes it is a repeat info.But in a form thats more like a chart.Which is easier for people like me that have a hard time processing sentences with numerical info.
Anyway your tutorials are super helpful noname! Thanks for all your help

And to address the topic of the differential widths.I've thought about that. And I dont think it can be very much.And the reason I added track widths is because I'm considering fabing LCA's(along with other people) And knowing the track width of a donor vehicle. Will help us decide how much we need to lengthen the new LCA's. And yes the Festy/Aspire would have a much wider track width.Along with relocated upper strut mount points.

Maybe we can get a more complete chart and add it to the sticky. Axle data is easy to acquire, track width is a little harder.

I can get a measurement on the escort gt half shaft as I have one sitting on my bench. My xr2 half shaft is already in the vehicle or I would go measure that.

Hey Zoom thanks for the info. So what you found is that they are within 1/8" of each other.Thats great news for those that cant find the inter shaft.Or running a LSD and not concerned with torque steer. Thanks for the update.
