Rear CV joint compatibility

Tapani · #1 03-28-2012, 10:37 AM

Do you guys now if a rear CV joint from another Subaru model can be used in the SVX?

I need to replace the "long nose" visco RH CV joint with a LH one to fit the Torsen carrier.

No scrapped SVXs here to pull from.

I bought a shaft from a R160 1997 Sti - it has 22 splines against the 30 in an SVX joint and the whole joint is smaller in diameter.

How about later Legacies? Plenty of them around.....

Thanks,

Tapani

I think any of the Forester Legacy and Impreza from about 97 up will work (other than the STi)

Ok, thanks.

I measured the outer diameter in my -06 3.0 Outback and this is 72.4mm while the SVX is 78.1mm and the Sti is 74.0mm. The internals in the SVX joint are quite a bit larger than the STi....

I ran into another issue .... found a LH SVX drive axle to swap on the RH side. I checked the grooves for the CV joint snap ring within the Quaife diff. They are way too deep for the SVX LH joints to catch.

The Quaife is marketed for all 1993-2000 Legacies and Imprezas.

This makes me think that the Legacy CVs might have longer splined sections (though the 1997 Sti shafts I looked at had the same length as the LH SVX has). If you look at the photo in the link the nose does look longer.

You guys who have swapped to later rear diffs how have you handled this? The shafts slide into the diff ok, but the snap rings will not catch the grooves.

Anybody?

Thanks,

I['m having the exact same problem you are w/ my 04 outback diff.

It'll go in, but it doesn't want to catch. So it'll move out of the diff on occasion.

I'm sure the only thing you need to do, is swap in the correct axles that correspond w/ the diff. Hence why I'm driving a distance to meet w/ Nate to get the axles that came out of the Diff-donor car!

Pls let me know how it goes. The SVX inner CV has 30 splines on the axle side. I trust there's a 22 spline version of the later joints around too. There's some doubt if the outer joint fits the SVX knuckle. When are you going to get the 04 axles? Thanks in advance, Tapani
