DISCLAIMER! After running on the Corsica Axle for 18 months, I finally popped the axle. The axle IS shorter than the Fiero axle. It is a direct bolt in, but if you overextend the suspension, and have bad motor mounts, you will lose the axle, and do other damage. The tripot is swappable with the Fiero axle though.
Purple Reign and I were experimenting with axles this weekend, and discovered that the passenger side automatic axle from a 1996 Chevy Corsica is identical to the Driver's side manual axle from a Fiero. The only difference is the ABS ring which is pressed on to the outer axle spindle.
The inner CV Tripod on the Corsica consists of a much stronger bearing and tripod housing. It slips right in and is a direct replacement for the stock axle for those running higher horsepower engines.
The axle shaft is the same size as the Fiero shaft. This means that the inner tripod from the passenger axle on the Corsica can also be installed on the inner passenger axle end of the manual transmission.
Just an upgrade idea to add some strength to the drive axles.

As much as I would like to make a profit from this, the Corsica axle can be bought complete from a parts store, and slapped in with no changes to the vehicle or axle other than to knock the ABS ring off of the spindle.
The only thing you would need to change if you wanted the longer manual axle to have the larger tripod and bearing assembly would be the inner CV Joint bearing and tripod.
Just remove the old Fiero end from the axle, slap the Corsica bearing assembly and tripod on, and clamp the boot in place. Stronger CV Joint, stronger axle.

I will look at junkyards, are we talking about automatic v6 Corsica's?
My info shows that axle used in MANY 96-99 cars of this type, I can get them literally by groups of 10 for around $25 a piece.
Yes, 3100 V6 Automatic Corsicas. The Passenger side axle has the male end on the transmission end of the axle. It has a heavier duty tripod than the Fiero manual axle on the Driver's side. When you compare the two, you will see the difference, easily noticeable.
The same inner tripot on the Corsica SHOULD also work on the Passenger Fiero axle. The bearing assembly will have to be moved over.
I am running a 1996 Corsica Automatic passenger axle in my 2.8/Isuzu 5 speed Fiero Driver's side right now. Just knock the ABS ring off.
The outer CV Joint is nearly identical, and the bearing splines line up perfectly with the Fiero hub. Technically, with some machine work on the hub assembly, you could install an ABS Sensor and run ABS with an ECM that supports it.

ok i need to do this upgrade so let me see if i got it rite to do this i need 2 P/S auto axles from 96 corsica just knock off the abs sensor rings and switch 1 pair of ends on to the P/S fiero axil so i would have on the fiero D/S i would have the P/S corsica axle w/o abs and on the P/S of the fiero i would have the stock axle with the P/S corsica ends? is this rite??? . i think i got it but im not sure how to do the other side pictures please also does this work on the getrag 5spd

all fiero manual transmissions used identical axles.
excellent information, as my 65eHD uses a left side manual tranny axle on the right side, with the inner tripot from a GTP. I may be needing shafts, haha. Found some more applications that use the same axle.

so how do you assemble the P/S fiero axle im still slightly confused can i uss the P/S corsica axle ends? or........
That part may take some engineering on your part. As far as I know, the tripots and bearings can be swapped between axles. This information MAY be incorrect as we did not have an axle on hand from the P/S of a Manual Fiero. The shaft sizes look the same, so the bearing SHOULD swap over.
And yes, the inner CV joint from the P/S of the Corsica should work on both sides of the Getrag transmission.
Someone with access to both the P/S auto axle of a Corsica and a passenger axle from a manual Fiero should experiment to confirm that the tripot and bearing can swap.
Edit for clarification.
The inner tripot on the Passenger side axle, and the bearing for it SHOULD be able to swap over to the inner axle end of the Fiero passenger axle. SHOULD is the key term. We did not try it, but seeing as how the axles are the same size diameter, the splines may also be the same.

Just got a PM from a member about the 96 Corsica Passenger axle being too short on his 4 speed Driver's side on his Fiero.
Bumping this to refresh the topic, and further discussion on this subject.
The Cosica auto axle IS shorter by about 1 1/4". I thought this topic was about the tripod joint being stronger in the Corsica Axle and the ability to swap it over to a Fiero axle shaft.

Interesting. I have the full axle in my car with no issues, and it measures out right.
The tripod WILL swap over.
Let me qualify this: Yes, I have the full axle in my car. After some more research tonight, NO! The Corsica Axle, as a WHOLE may not fit, the length may be too short. I am unsure as to why mine would be different, but the axle DOES fit. Moving the Tripot over to the Fiero axle is a good solution though, as it will provide a stronger CV joint for the axle as a whole.
