u joint lube issues

I found the u joint had been running without any lube.....and it did not like it.
Long story, but if you haven't had the joint removed make sure you pump the housing full of grease.

One of my points earlier was to make sure you pump it full of the PROPER type of grease. It is possible to pump full of the WRONG type grease, and on the first full revolution, there will now be a big, empty void where grease used to be. If you use a high-melt-point grease that is not designed to fill-in behind something (the u-joint) moving it out of the way, you'll end-up running your joint without lube again.

Find the John Deere video on-line which shows how the Cornhead grease is formulated to work correctly in a situation like this, as well as in steering gear boxes. DD
 
I have pumped in a 14 oz cartridge of grease but none is coming out of the speedometer housing opening . Is it possible to over fill and push grease down the torque tube ?

If the cavity was empty, it could take more than one tube to fill it up. The only way to verify the seal is to remove the torque tube - Or you could just pump in another tube and see what happens. I would try option 2.

Ford specified 8oz in Model AA trucks. You may have back filled your transmission. Pull your transmission top off and check.
 
Hope you find the grease ...

Tried to get cornhead grease here and needed to buy a case. Don't know about Arctic grease. Seems unlikely.

A video of the supposed differences between NLGI 0 and 2.

And Penrites brochure on greases is interesting for all sorts of things:

Some constant velocity grease is supposed to be NLGI 1, (like the Arctic stuff).

My ****** is all original with metal slingers and open bearings, and I had the top off when I pumped Mystik JT-6 High Temp red grease into the U-joint. I also had the speedometer gear housing removed. I pumped one 14 oz. tube of grease into the housing and it was just starting to come through the speedometer opening and the ****** rear bearing at the same time.

If you pump some more in it won't do any harm, and you should soon see it coming out the opening.
 
John Deere grease has the property -I believe it is called thixatropic. It is normally solid and if stirred up it becomes liquid. Locktite has the same property which is why they say shake it before use-makes it more liquid to flow on the threads.

So when the u joint spins,the grease thins and lubricates. When it thins it also migrates to the front driveshaft bearing.

Chrysler Corp used to provide us with a special ball joint grease, that was designed to constantly "channel" & move around.
I "wonder" if such a grease is still available???
