Ball and trunnion- driveline squeak

[nbn]

Test driving after engine rebuild, the first 5 miles were pretty uneventful., other than a slight vibration at speed that I attributed to flat spotted tires.

 

In the last 1/4 mile, a rhythmic squeak appeared while moving. The sound was too rapid for wheels/brakes so I felt the issue would be a driveshaft problem.

 

Pulled the driveshaft and found a "crunchy" end. Opened the end and found a metal sliver in the grease, a loose washer and a worn/damaged ball. My guess is that this is the culprit for the squeak and the vibration.

 

So.....it looks like a decision is about to be made to rebuild the ball and trunnion or update to modern u joints.

go with modern, much smoother

Probably cheaper/easier to replace what you have.

On drive lines, I assume that if one u-joint is bad I will expect the others to have just as much wear and replace all.

 

IMHO, would be a improvement to replace with modern u-joints .... cost a little more upfront to have the work done to the drive line.

Then if future issues arise, is a simple $15 part at any auto parts store.

I have a complete 1940 shaft that has ball and trunnion in place with smooth movement.    cost a bit to ship to texas i imagine but its yours if you want it.  

2-2-349 1310 flange yoke (1310 u joint) is what we used to begin building the new shaft its specifically made to replace replace the ball and trunnion.

Thanks, but it looks like we're going to do the upgrade. Knowing the difficulty of obtaining quality rebuild parts now, it only makes sense.

Don;t think anyone is new building these parts, which means you get NOS, if you can find them.  Bernbaum's can usually help out, though I don;t know if he has housings anymore.

I sent you a PM and I have the kits and housings for the 40 Plymouth.
