The Stovebolt Site Forums The Shop Area Driveline U-joint question

This u-joint doesn't look like the one in my 38 Chevy shop manual for a 1/2 ton. It looks a little more beefy like the one on 3/4 or 1 ton judging by the figures in the manual. Does anyone know if this is correct for a half ton?

According to What I can find, that is a 1940-1953 U joint. 1933 to 1939 are "open" drive shaft and the U joint looks more like a modern one. So I looked at the manual...and it looks like a torque tube to me. http://chevy.oldcarmanualproject.com/shop/1938/38csm086.html
And that would be just like what you have in the picture. So further looking got me to here: http://www.vapinc.com/chevy/Universal%20Joints%20and%20Parts/main.html I think this is the folks that make the parts every one is selling. Might be worth a call for more information.
Some one here will know what I am guessing. I hope you get some better information than I was able to find.

Thanks Steve. The figure in the manual seems to show that mine is like the one in the bottom illustration. I'm in the process of taking my driveline apart, and want to make sure I know what I've got before I start ordering parts. I'll definitely check with the sources you provided. Thanks again.

Okay, so I'm not sure how they got this in to begin with... I'm trying to disconnect the u-joint. It looks like a u-joint for a 3/4 ton, and I'm driving the bushings out of the yoke like the manual says. The problem is that there's not enough clearance to fully drive the bushings out before they contact the transmission housing.

I can only drive them about halfway out. On the 3/4 ton, the transmission housing has some cutouts that allow the bushings to be driven out as shown here . On my half-ton, the transmission housing doesn't have those cutouts.

So, how do I get the driveshaft out if I can't take the u-joint apart? Do I need to pull the rear end leaving the u-joint connected to the transmission? Is that even possible?

With your setup it looks like the only option is to pull the diff back. Then you can reach down the center of the u' joint with a 9/16" socket and remove the center bolt and whole u' joint assembly.
