47 U-joint lube
Here is a video of my U-joint that was put in new 3 years and 45,000 miles ago and the lube that was supposed to be lubricating it.
https://youtu.be/Noxa1dDiNG8 Jiffy Lube pumped their chassis grease in there every 1,000 miles when they pumped it into the other 18 fittings under the car. Still, very little was in the U-joint cavity when I opened it up but the U-joint seemed to be plenty moist with what was there. Still, the U-joint has worn out prematurely in my opinion. I'd hope to get more than 45,000 miles out of one. I surely would not put John Deere Corn Head grease in there. That, mixed with the transmission oil leaking into there, would be way too thin if it stayed in there at all. (Last time I used that it was all gone when I opened it up to replace the U-joint.)

Re: 47 U-joint lube
Hi Craig.............
Some thoughts on your u joint situation. Not a good u joint to start with; not enough grease pumped into the cavity; and lastly and probably the culprit, the wrong kind of grease used by Jiffy Lube. In your video the grease looks to be very thin indicating they use NLGI-1(it is cheaper). I would use only a NLGI-2 which contains moly. At work we always used the #2 in all of our heavy equipment and truck applications. Hope this helps. Good luck!! |

Re: 47 U-joint lube
Yeah, I'm not sure how much grease Jiffy Lube actually pumped in there. It is very hard to get a grease gun on that zerk squozen between the clam shell and the tranny mount.
I think, when I put it all back together, I'm going to put the clam shell together with that zerk on the top under the floor. Then, when I take the floor up to adjust the clutch every 5,000 miles, I'll shoot half a cartridge of good thick stuff in there since it's going to get thinned out so much by the tranny oil anyway.

Re: 47 U-joint lube
Sounds good. Get some kind of moly grease, it is usually black in color. I think it would work for you especially since it is getting thinned by the tranny oil.

Re: 47 U-joint lube
Have the original U joint in my '35 fordor that now has a little over 71k + on the odometer. 20-25k of these miles have had John Deere Corn Head grease in the U joint. Last May, @ ~ 69k I had the rear out to rebuild it and install 3.54 gears, and the U joint was in perfect condition.
Standard chassis lube is not the best lube for the U joint. JDCHG works well in the U joint and also mixes well with the small quantity of gear oil that normally comes through the rear transmission bearing. Based on the picture you posted of your last U joint failure, and now another failure in 45k suggests to me that you have something seriously wrong in your drive train that's causing these premature failures.

Re: 47 U-joint lube
Ford used gear oil and soda soap mix. This was as close as they could get to a thixotropic grease back in the day.
John Deere needed a grease to work with a gearbox that is very complicated. It has to mix one drive force into two to drive the pickup mechanisms that pull the corn stalks into the combine through the corn header. Due to the unique characteristics of the design, it needed a lubricant that was different than any they had used before. The stuff works with very little problems with seepage. Here is what one example looks like. http://www.worthingtonagparts.com/Jo...EW-WN-AH209794 You can use what you want but this stuff works. Gear oil you can get but soda soap is a different story and then what ratio do you mix it? Ford never explained this stuff. |

Re: 47 U-joint lube
I'm not sure that lubrication was the problem as much as weak U-joint bushings. As I said, although there was not a lot of lube in the cavity when I opened it up, the U-joint seemed plenty moist with lube. In both of my U-joint failures, the U-joint failed when one bushing disintegrated, although the remaining bushings were very loose showing a lot of wear. Hopefully, Mac's NOS Ford U-joints will be better.
