Well I received some free shafts from Goerend Bros. that they pulled out during trans rebuilds to use for an adapter shaft for my Spicer conversion. I am a bit confused though, since the shafts I received are all 1 1/4" in diameter at the spines that enter the transfer case. I found on a couple sites that the diesel 4x4 shafts should be 1 1/2". Does anyone have a 4x4 transmission out of a truck that they could measure the output shaft of?

Just an update. I checked the shafts tonight, and they are only 23 splines, and the same size as 1/2 ton trucks and Dakotas. I verified this by fitting the shafts to a Jeep Wrangler np231 transfer case I have, and tghey fit perfectly. Common sense tells me our diesels use larger shafts, but I e-mailed Goerend Bros. to see if they may have sent the wrong shafts, and the reply said that all of the shafts i got came from diesel transmissions, a 47rh and a 47re.

So if anyone could possibly check on their stock diesel transmission output shaft size, I'd very much appreciate it. Otherwise I'll be pulling my t-case this weekend just to measure the shaft in my transmission.

I just measured a 47re output shaft ...it's 1.220 ... the trany is out of a diesel .

I hate to "bust your bubble" but they use the same shafts in the 46 and 47 RE. The output from the X-fer case is larger, but the tranny shafts are the same size.

 

Dodge is about all Dave Georend works on. I'm sure he would send you the right stuff.

 

Thanks very much! I'm very surprised at the size of the output shaft. I had an old Jeep J-20 T-18, and the output shaft was quite a bit larger than the common 1/2 ton shafts, and common Jeep 23 spline shafts. I was just confused because a couple sites, such as this one: http://dodgeram.org/tech/transmission/nv4500_spec.htm list the size as 1 1/2" with 29 splines. That page is for an NV4500, but the t-cases are the same. Thanks for the input!
