Now today-I reassembled the axle I bought this week and prepared it to return to the store since it is obviously the wrong part in the box and not a #9572 as I was supposed to get. It measures 1.030 diameter a original equip manual fiero axle is .820 and the outer joint on the one that they sold me is huge! looks like it could turn a dumptruck . I have no idea what it came from but is not a minivan. On the left is the welded axle I had made--15.25 in in the center is oem fiero axle - 13 15/16th in oem was too short-----welded is too long. and on the left is the reassembled axle to be returned--hope they don't notice the hose clamps If autozone cannot find me a correct # 9572 then I will just go to a different axle shop and purchase the axle since I NOW know how to build one myself.

Update+ I was mistaken on the welded axle length it is 16.25--being 2 5/16th longer than stock
Last night I went to autozone and had them pull another # 9572 axle--it was identical so the part must be correct? But it is absolutely too big in diameter to fit into these fiero manual outer cv joints.
I do not know what to do.

Jeff try an 88 stick outer cv on that #9572 axle . Joe

Does anyone know for sure if the 1988 manual fiero axles are larger in diameter than previous years?

I have an 88GT 5 speed. I couldn't check the diameter of the splined section but the shaft itself measures about 1.065".

The Fiero store lists the same part number for 84-88 manual drive axles

Just in the garage a moment ago messuring the splines and such from my manual axle on the fiero

This is a pic of the passenger side th 440 axle that was in my car The cup and everything is the same exact size as my manual fiero's axle, It also matched my manuel shaft. The only difference is the thread lenth.

Earl,
I have been telling them to look up a 94 pontiac transport 3800/4spd tranny and they come up with part number 9572 which others on here have stated will work.---I just don't know what to do at this point.
I am thinking maybe return the axle # 9572 that I purchased and try another axle shop---take the manual fiero axle that I have to them and tell them to find me one approximately 1" longer with same diameter and number of splines and then build the halfshaft myself. Because for some reason-part number 9572 absolutely will not accept the outer fiero manual cv joint.

Take the calipers and check the diameter of the Fiero axle that you think is a manual. As I posted earlier, my '88 manual axle calipered at 1.065" on the non-splined portion. It sure does sounds like you do not have a Fiero manual axle.

Another possibility is what I found in another thread concerning axles problems. This information found this other thread that says that some remanufactured Fiero manual axles used different shafts than OEM.

This is a quote from a post by BV Motorsports

"From an old thread of mine, hope this helps:
Well, I got my car back together and gave everything a once over. I checked every nut and bolt that would have been touched by the tranny shop when they removed the trans. I picked up a 94 3.8L Oldsmobile mini van axle and went to remove the hub side CV and add the CV from my new fiero axle. Well turns out not all reman compaines use ACTUAL fiero axles!!!!!!!!!!!!!!!!!!
So I had to make a trip to the j-yard and find an original manual trans fiero axle to pull the hub side CV joint. The manual trans one is 1.080 and the auto is .935. Found a CV and swapped it to the new Olds piece"

Sanderson.
thank you. I guess I will begin scouring the (u- pull- its in) north florida and see if I can find one the correct size.

I'm real interested in this since I got a 4.9L/4T60E sitting the garage with intentions of installing it in an 88 coupe.

Hiya Jeff, watching this with great interest. I KNOW it won't be long before you solve this! Wish I was closer to help ya out.

For those who are watching because you have a 4t60e on the horizon;

for your passenger side this is what you need---1996 Olds Silhoette 3800/4spd passenger side axle ( a common gm axle part # 9572) and you have to remove the outer cv joint and replace it with an OEM manual fiero outer cv joint.
The aftermarket-rebuilt manual fiero axles were often made .850in diameter which will not fit on the minivan axle.
If you have a manual fiero axle which is 1.030in diameter then you have the correct one.
Good luck.

I was just about to ask if you had done the above; I remembered reading it or something like it on FieroAddiction.com; I seem to remember it caused some confusion for someone on the same issue.

OK Jeff, I get to pick on you a little bit now. You can SMACK ME when you see me next Sunday.

This entire thread is why I am glad I am sticking with my STOCK FACTORY 5spd

On the UP SIDE, we will be able to answer people correctly when the question gets asked again.

I can't wait for you to drive it down here. I can see your smile already. BTW, it will be a blast having You, Earl, and ME driving around terrorizing Orlando in our 4.9's

I will give you a call in the morning.

Jeff; I got my axle shafts this afternoon from CVJ Axles and they fit!!! They wont pop out and they won't bind up under max travel, I'll bet we wound up with the same parts via different paths.I'm so thrilled that I don"t need custom axles!
I'd like to talk to you,pm me with your # Or go to my thread ( off the back burner ) and get my # and call me,If you get the machine don't let the message fool you listen all the way through.
In closing our thoughts are with Hendrick Motorsports Joe

Jeff, glad to hear you got it sorted out. Just goes to show everyone that sometimes you can't trust aftermarket parts, especially when it comes to our Fieros.

Amen Darth! Joe

Some more info for this thread, I found out that the left inner tripot is difference between the left inner tripot for the od trans and the non od trans, the spline count is different by one spline. The od tripot is identified by a small step on the end where it goes into the trans.
Total cost on axles including the left inner tripot $51.25 Joe

Update, Jeff we need an update on the old axle problem.

Jeff was by helping me with a cradle drop today and I think he found what he was looking for at the bone yard. I'm sure he'll be updating us as he digs into it again.

I had now idea the axles I gave him were aftermarket, but after looking at the ones I bought from Rockauto.com, I can see where the one I gave Jeff was smaller in diameter. Who'd have thunk???
