Hello;
Trying to get back at this project....Working on the propeller shafts and found the U joints in need of replacement. I found a Spicer catalogue on line and it looks like #5-178x will work.
Can anyone confirm this or have a current model # that works?
This is for my 52- 9430 1 ton

I used that part number on my '48. I had to modify one of them for some reason that I can't now remember, grinding a little metal off for wrench access or something similar. Not a big deal or I wouldn't have done it.

Measure old ones, search by dimension.

Should be a Spicer # 1350. If you ask for that at O'#### or similar, they will want an application and their books don't go back that far. So pick a u-joint for a Chev 3/4 ton from however far back their books/computer go. That should be a #1350. Next size up is #1420. That won't fit. Take the dimensions with you to check.

A better solution would be to go to a driveline specialty shop and ask for a #1350 u-joint. There's one near where I live. They don't ask you year, make, model, engine, paint color, etc. They just get you what you need. They carry quality (Spicer) parts at better prices than your generic parts store.

I used the Spicer catalogue to cross reference the 1350. I also used an indicator to measure to confirm the size.

There's actually a place here in Pgh Pa called Driveline Service that I've delt with numerous times. I've got joints installed while I waited cheaper than I could of bought em and Installed them myself. Not to mention ,"the support small businesses thing " I like to do. I'm sure there should be something similar in your area. Hopefully

Humm. Nice chart

I ordered 3 today and will confirm they work/ fit proper
I like doing the work when I can. The old u joints needed to be pressed out.

You can use a ballpoint clamp/press without attachments. It works quit well really.
