Can't say I've ever seen a rear universal like that with a grease fitting on the backside of one of the cups. Though perhaps not too significant, you'd think it would create an imbalance unless the construction of the opposing cup was somehow modified to compensate.

Normally the grease fitting is on the interior at the intersection of the 4 posts.

PS - if you don't get new rear u-joint retaining clips elsewhere, the Minnesota Packards region of PAC offers them for the 51-54 models at $10/set.

Kev - in addition to the needle bearings, balls and pin, the other critical place to examine a ball & trunnion joint for wear are the interior channels of the housing. Fortunately NOS housings for the junior models with Ultramatic are still available, but those for the seniors are pretty much extinct and have been so for some time.
