I've been trying to "Make" a passenger side Axle for my 3800SC w/ HD automatic. I went and bought a NEW Fiero "Stick" Driver side axle, But I Cannot FIND a "GTP " CUP, anywhere. I've already READ the "how to make" articles, seems like I'd need about 5 different axles to actually Make 1. Doesn't anyone sell these things "Redi-made" ? I need 1 for the passenger side of a HD trans. Thanks
The cup that came with the HD trans , takes a MUCH Larger tripot, I can't find an axle that will fit both the Large tripot (that fits the CUP) And the cv joint(from the Fiero manual Trans.) I've been "Told" that a GTP cup will fit the stock Fiero Man Trans Tripot. Is this True? I really don't want to go BUY 5 different axle combo's trying to Find a workable Combo, It gets expensive. the stock Fiero Man trans Axle/tripot is the correct length, just the tripot is too small for the cup.
Nope I just built my axles not that long ago. I used a drivers manual and it fit in the cup that came with my tranny. The fiero axle ans bearing thingy fit perfactly. But my motor and tranny came from a 2002 regal, not sure if that makes a difference or not.

that I think is the difference, the regal Trans. Was it a regular regal or a GS ? can anyone verify this ?
That I don't know, I think a gs? One would think that all "4t65e hd's would be the same cost wise. The only thing I noticed doing my axles is that the auto and standard fiero axles are different diameters but they both fit my tripots. Mabey see if you can locate a junked regal at the wreckers. Over the winter I want to locate another drivers manual and replace my drivers side so it's larger.

I "Suspect" only the SC models got the HD Trans. I May HAVE To buy a Entire New Axle just to get the CUP ! This Swap is getting old real fast. The entire Engine is new, new AC comp, trans rebuilt, All mounted in the Cradle, all that is left is exhaust, 1 axle, and to finish the harness. I hope I can finish it without throwing in the towel.

Like I said, see if the wreckers has one cheap then buy a new boot and put it together.

Most of the yards say they don't "Bother" with axles. figure a brand new one is $70, and all I want is a CUP, then shipping... I'll give it another try on Find a part on the internet.
Yes - you need the tripot cup for a GTP - or Regal GS - there are 2 different Tripot cups - the larger ones are from Bonny's, etc. I believe that certain Transport Vans and Silhouette vans that had 4T65eHD trans also have the correct tripot? Send a PM to Mstangsbwre - he sometimes has axles built up or has parts that he's wiling to let go. He can tell you exactly what parts you need to build the Passenger side axle.

I tried find parts.com, I usually get dozens of replies, on this NONE. Whats a new series 2,engine all New,(+new AC comp) w'4t65HD mounted in a 86 cradle with 1 axle done WORTH ?
The problem is there are many different design CV tripot bearings and tripot end "CUPs" floating around out there. If you get the wrong one, you're not going to be able to use the stock Fiero parts with it.
What you need is a inner tripot end "CUP" from a 1997-2003 or so W-body GM car that had the 3800 SC engine. C/H/G Body cars used the same trans but likely had a different design inner tripot end "CUP" that installed into the trans. The stock Fiero MT CV axle parts are INCOMPATIBLE with this different design.
AND if you go to the parts store and buy a new CV axle, it will likely have a totally DIFFERENT design inner tripot "CUP" and matching bearings that may not resemble anything GM ever put in a car.
MY ADVICE: Call Morad Parts Company and tell them what you need. They deal with enough Fiero people that they should be able to get you the correct tripot end "CUP" you need to complete your swap.
what ryan said, i used to work for ed.. he has a box of oem passenger side axle cups off hd tranys just for this reason.. I thought they were less then 30 shipped if i remember correctly.. dont hold me to it tho... 216 671 3736 is the shop number

Other years may be different but when Installing a 06 or 07 3800SC GTP powertrain, the 4T65eHD trans side cups and inner assembly fit the medium diameter GM axles...Transport van, Cavilier, Beretta etc. The GTP outer axle assembly inner fit the Fiero cups on that end. In summation use GTP trans side Tripod cup assembly (inner and outer) a suitable length axle (Beretta, Cavilier, Transport Van) the GTP wheel side inner assembly and the Fiero wheel side cup. Depending on how your engine is mounted you will need to measure and choose the axle bar size needed. A while back there was a chart posted with all of the popular axle lengths. Here it is. From the archives: While there are some very good tips on this forum for swap axles, the final axle choice will be determined by powertrain location. Having said that lets take a look at CV axle compressed total lengths. Here are the popular choices: Drivers sides .......................Passenger side Fiero Manual axle 22 3/4" Fiero Auto 21" 95 Beretta all 20 1/4".................. 21 1/4" 95 Corsica all 20 1/4".................. 21 1/4" 95 trans Sport Auto 20/ 1/4" ............... 23 3/8" 98 Lumina auto 20 3/8" ............... 23 1/2" 98 Buick Regal 21 3/8" ................ 02-04 Cavilier auto 21 3/16" .............. 21 3/16" 02-04 Caviliar stick 23 5/8"
The above axles in most cases must be assembled to the 4T65eHD inner tripots and the Fiero outer members. So to answer the question measure up and choose. There is no univeral swap axle set.

My trans is setup with stock trans mounts, so the engine/trans is centered, Both axles are the same length. the stock Fiero drivers side axle fits perfect. I need to make the pass side the same length (only problem thus far being the CUP and Tripot.) I have a new Manual trans axle for a drivers side to use for the pass side. Now I Have the INFO, finding the Cup and Tripot..... OR, does anyone HAVE a "Already Assembled Axle" to fit this, the same length as a stock driver side axle ? Have not called ED yet. Thanks
The "new" manual driver's side axle you have, is it a GM part? Only reason I'm asking is that the aftermarket ones will sometime (usually) have a complete end-to-end solution in which the tripot cup and tripot are unique to the manufacturer and not GM compatible (when you're trying to mix & match parts).
I know Joe (Fieroking) has run into this a few times, and almost always has to get rebuilt GM axles or wrecking yard ones to make it work.
