I want to replace the ball gaskets on the torque tube on a 1951 chevy powerglide car.. I’ve never did this before so I have a few questions. It looks like with the rear springs in place and frame on jack stands I can remove the hanger bolts and slide the differential down on the springs far enough to remove and replace the gaskets. Will this idea work or is there a better way.

On my two old trucks, I position the jack stands under the rear chassis and let the rear axle hang down in the air.
This pulls the torque tube away from the transmission far enough to be able to slide the ball housing towards the rear of the car, disconnect the u-joint, and let the torque tube swing down without disconnecting the rear axle from the springs.
Then you can mess with the ball housing gaskets. There was a good article a long time ago in the G&D magazine where Junkyard Dog explained how to determine the correct number of gaskets to get a good seal.
I think you'll be able to find this article using the search function of the digitalized G&Ds.

I tried a search of past G & D's but had no luck. If you do find the issue date, please post it here. Thanks.

There is an article by Dave Cavagnaro in the January 2009 G&D.

I need the same info/article but am not a VCCA member.
Can someone post a pic of an original NOS gasket that seals the outside of the ball to the mounting ring?
Was original made of rubberized felt like seal inside the threaded ring?
Seal pictured at chevsofthe40's appears to be cork which does not seem like a sturdy seal for the ball joint cup considering the up/down movement of the cup, though slight as it may be.
Felt seems like it would be perfect.

The last one I replaced on a ‘49 3100 about 3 years ago was cork. It seals great. It was a little thick so I had to sand it and make it thinner.

The 49' 3100 was a truck with a manual transmission I presume. My car is manual 3spd. I can't recall if there was a liquid manual transmission fluid in the ball or just grease when I removed it. I assume the seal prevents dirt from getting into thick grease for the ball joint instead of preventing a liquid transmission fluid from escaping. Is this correct?

In a manual transmission the ball area is lubricated with gear oil that transfers back and forth with the transmission. Your shop manual should indicate how you fill that area initially.
The seals keep the oil from getting outside the ball area. There is no internal seal between the transmission and ball area.
