I'm about to tell you something you do not want to hear. Support the frame, ahead of the rear wheels, and detach the rear axle assembly from the truck. Roll it back or pull it back on a floor jack. The u-joint will stay on the transmission. It can be removed by reaching through the assembly with a socket and extension to remove a bolt and washer that secure the joint to the transmission main shaft. Good luck.

Your u-joint is different from what I encountered with Lurch's u-joint, but once you get yours out, you might want to check the slop in the u-joint bearings (trunions), the wear in the torque tube bushing, the condition of the clutch, the pressure plate assembly, the clutch contact surface on the flywheel, and the throw out bearing. If the throw out bearing is a carbon disc, you can get a replacement with a ball bearing, which is much better.

Last summer, I fixed a squeal in my u-joint and I documented the project on the Stovebolt website. Note, you might need to register with that site and log onto it to see the photos. There is no charge for the registration. Here's a link to the story: https://www.stovebolt.com/ubbthreads/ubbthreads.php/topics/1503661/lurch-is-squealing-gotta-fix-him#Post1503661

Hope this helps. Dean

Thanks a lot for pointing me in the right direction. Since I am new to this type of vehicle, I just have to take the challenges as they turn up. So I will just study the removal of the real axle. Also waiting for the registration at Stovebolt.com

I suggest that you  get a copy of the repair manual and part numbers book. There are a bunch of repair manuals on ebay now.

Here are links to part manuals that are online. Using these, you can find out if a part (say the u-joint) was used for multiple years (it has the same part number), which will make it easier to track down parts.

Thanks for the links. It's a type OA truck 131, single rear wheel. I have problem finding the correct illustration on this page 1929 - 1954 Chevrolet Master Parts & Accessories Catalog

I have the printed repair manual for Chevrolet 1929-1936 passenger  & truck in danish. It's equal to the online Chevrolet 1934 shop manual 1934 Chevrolet Repair Manual. I think the way forward is to loosen the rear axle and slide it back. As Mike indicates. Picture below is from the 1934 shop manual

@u3493 You will not always find an illustration that is specific to your vehicle in the Master Parts Catalog. Those are for helping to identify the group number of the part you need.

Stovebolt is a great site, but not much activity over there for older models or un-modified trucks. 

I have a 1936 Chevy 1-1/2 ton truck so I can relate to your issues. Don't hesitate to send me a private message. I have a small stash of replacement parts.

I don't think you mentioned why you are taking your truck apart.

Mike

@35mike Good idea. The truck has been left sitting in a barn near Trondheim, Norway where my son married the owner's daughter. It came to the farm in 1933, and was in use until the beginning of the 70ties. It was built in a GM factory in Denmark. I have been restoring a Volvo P1800 1962(mine since 1983) and a Opel Kadett C 1979model(owned since 2019). I just got retired now at 67 years old,and I needed a new project to fill time and head. So I voluntered to give it a second life, since the owner had no plans. The engine was overhauled in 1959, and the cylinder walls looks very good. The head will need a workover. And all the mechanics, as well as the electrics will need to attended. The  engine block will be taken out and inspected, especially the lubrication. The outside shall remain with the patina of today. 

I'm still in the disassembly phase, but will need many parts, so your stash will be interesting

@u3493 

Hei u3493

I just reread this thread and I'm trying to figure out why you are trying to remove this.

Maybe I missed it?

Unless there is something obviously wrong with the universal join/drive shaft/rear axle, I wouldn't tinker with it.

The joint looks to have been oily and thus well lubricated.

I think I would have started with just draining the oil from the transmission and rear axle and refilling with new oil.

That's what I did with both my 1929 car and 1946 truck and have had no issues with either of them.

PS

Jeg har slektninger i Tønsberg og Moss og jeg reiste til Trondheim i 1991 da jeg var på besøk hos dem.

Så bestemte jeg meg for å lære litt norsk.  🙂
