Differences in half shafts???
I have 6 halfshafts here and there are 2 different part numbers, so my question is: is there a structural difference between the d36(auto) halfshafts and the d44(man) halfshafts? All of them are the same length and use the same u-joint.

I have the same variation in my collection of halfshafts and are not aware of any physical differences

Post the part #'s and if there's a Spicer number on the label post it also.

this first half shaft is out of an autmatic car. on the label it is:
10223032-9YA
25 jan 94 918851-1408
on the end is: spicer
FA17
F3 289
41 KAG
the next half shaft has been in my 89 6-speed car for 20+ years. we took both shafts out on the line. evidently more hp + 4.09 gears and m&h tires was an overload. and new stub axles. but i have no idea what these came out of, auto or man.
14093105-5yz121
on the end is: SPICER

I'll try to do this in one "pile"!
14046912 - '84 - '88 A4 with out 6 way seats A42original part number for an '84 AT with out 6 way seats
14041925 - original part number for an '84 AT with 6 way seats or MT
10054290 - '85 thru '88 A4 with 6 way seats and MT all
14093105 - a replacement for the 14041925 and production for '89 ? (in '90 the 14093105 was mixed with 10054290 for replacements)
10098291 - steel confirmed for '90 early ZR-1 and likely maybe the '89 M6 cars
10154277 - became the service and production replacement for all MT and A4 with 6 way back to '84 and thru '93
10223032 - production and service for "ALL"
Sleazy & Ralph - are your 14093105 shafts steel or aluminum?

I can only recommend the aluminum half shafts be replaced with steel ones as they are so weak and too easy to twist and snap them, even with an auto transmission.
I had the aluminum half shaft copied and steel ones made, they have not given any trouble since.

all my half shafts are aluminum.
gerardvg, i had a set of steel half shafts made, they were crazy heavy. when i moved up to the c5, i sold them, now i'm back to playing with the c4. on my original shafts, we twisted one into 2 pieces and the other twisted about 45 degrees. i may cut one in half and measure the thickness of the tubing and get some thicker tubing to weld back in. maybe send them out for some cryo time.

those were my 89 original shafts and they were replaced with steel shafts. it wasen't until years later when we quit racing the car and started modding a c5z that i got another set of used aluminum shafts. those would be the 14093105 shafts that i am working on now. i still may take a pair of the -032 shafts and have thicker tubes installed on the ends. should still be lighter than steel.

I've used many of theirs for projects and they're very popular - the entire country!

i can get some pics and measurements when i get home tonight. i see what you mean about not being able to reuse the inserts with thicker tubes. these shafts that i have should be good to get the motor/car broke in. maybe this winter i can get new hd shafts before we start to beat on it next year. need to get the cash flowing again, time to start selling some parts.

That's why I asked about the 14093105 part #. I found a snapshot of the early ZR-1 steel but I can't read 1 digit! It's no where near the 14093105 but I've emailed the fellow that it belongs to.

An acquaintance I like to consider a "friend" "SCRREM" here on the forum has been able to confirm the part number from his snapshot of the steel ZR-1 half-shafts that he removed. The steels were 10098291 and were replaced by the 10154277 originally and finally by the 10223032 for all service replacements.
