If you are having a problem with the U-joint life, be sure that the special heavy washer and bolt that secure the joint to the transmission output shaft are correct. If loose, the joint will move back and forth, and be damaged.The "family" part number is "7095". and they are sized for the year of the application, differing in diameter. The bolt securing the washer is also critical in length and thread pitch. If in doubt which is correct. refer to pages 306 and 307 in the "green book".

Allen is quite correct... regular bearing grease will not suffice in this area.

I also agree that grease is not the answer for the U-joint. I use 0-0 weight grease that is a heavy liquid and pour about two ounces into the speedometer turtle hole. Do use the grease on the Zerk fitting that is on the outer cover of the U-joint housing.

As Allan says above, most grease tends to harden and not flow into the joint. John Deere corn head grease (or equivalent) is designed to liquify in the area that sees movement or agitation. Please seek more advice before putting wheel bearing grease around your U joint. https://www.youtube.com/watch?v=7zNhli-J0Gk

the grease you chose to use will never be soft enough to flow into the u joint, the u joint will carve out a groove in the grease and the grease will not flow back to keep the u joint immersed in grease

Thanks for the advise. I decided to 'stick with the wheel bearing grease. It is in common use and is available everywhere. AND I have not heard of any problems with it. Thanks, Mike

Install the u-joint on the end of the engine. Make sure you get the clam sh*ll aligned correctly with the fitting acessable. Fill the cavity with grease (most like Corn Head), usually takes a full tube. Remove the speedo turtle, when you see grease there it should be full. Done. FWIW Paul in CT

I have the engine out of my 1937 and it is ready to be put back. How should I lube the universal joint? Should I just try to force lube into the trunnions? Or does it come apart? I was considering using wheel bearing grease or should I use something else? Thanks, Mike
