In the continuing saga of trying to take my rear end apart, I managed to get the U-Joint off today and wonder how much slop is allowed? The side to side movement is in the area of .050 - 0.060 inches. The ends fit fairly snugly in the casting but there is a few thousandths gap. Other than the little side to side motion it feels pretty tight.
What tolerances are acceptable? Do I need to look at replacing it?
On a related matter, it looks like the bushing is babbitt so I will be replacing it. I also plan to install a fun projects pinion bearing.
Side to side is normal. Measure diametral gap of trunion with a wire or feeler gage and report back. From your description, though, it sounds fine.
I need to get a wire feeler gauge - Meanwhile, I took some photos. The first shows the end fit while the second (arrows) show how much it can move side to side.
Put back in, the next care taker will be doing the same, plenty of grease and they last for ever!
Rivet back into place on the drive shaft and use. Once everything is in place it is self centering. The place you need to worry about wear is where the round fit thru the hole not how far it moves back and forth. That one looks next to new.
I think this a case of a slightly worn original Ford part
Is a better bet than some new replacements.
Tim, if you keep that greased, it will probably out last you and a couple more owners too! Dave
