Connected my rebuilt rear axle to the frame and noticed that there is about 1/2" gap between the ball cap flange on the drive shaft to where it would bolt to the end of the engine. Hmmm ... maybe because the flexibility of rear spring? Don't remember seeing this before.

Loosen the rear spring perch nuts just a little,pull driveshaft into it's place and then re-tighten perch nuts,replacing cotter pins.

If the ball is outboard the 4th main, then perhaps the square tang of the U-joint isn't seated?

Should look like this when the u-joint end is mated.

Mark,

Haul back on your parking brake lever and see if it doesn't pull the u-joint ball up a little closer.

Jerry,

I put the rebuilt rear axle on the frame yesterday ... no engine or brake lever installed yet. Just noticed when I set the engine pan in the frame that there was a distance I don't remember seeing before. The rear spring is in better condition than the one I removed. Maybe the spring just needs to be loosened and pushed forward.

1/2 inch gap
Most likely you pulled the vehicle forward and the slop in the spring moved the rear end back a bit before you put the pan in place.
I had the same issue and used the bolts to align things.
I wouldn't go thru all the trouble of loosening the springs.

I figured it was something simple .... there is no way to change the actual geometry other than spring fudging.

Mark,

Most likely when you have the weight of an assembled car sitting on the chassis, it will cause the torque tube to get closer to horizontal and have the effect of elongating it.

Jerry,

You should have seen me jumping up and down on the rear frame while trying to insert the second L type shackle. I'm sure my neighbors enjoyed it.

Did you put grease into the back of the planetary? It is a very good idea to do so. But sometimes the grease packs forward and can prevent the U-joint from going all the way in.
With a little careful pressure applied with the four bolts, the grease will usually squeeze back out in the corners of the U-joint square. (Slowly!)
Just a thought. Been there. Done that.

Mark,

Funny. I know exactly what you mean. I think my neighbors gave up following my antics years ago.

Most of us "old car" nuts are known in our neighborhood as being kind of "weird" but in a fun sort of way. At the neighborhood picnic I always bring my T and everybody wants a ride. I try to build coils during the winter time when all my neighbors have their windows closed so I don't have to worry about the smell of tar being traced to my house all the time. :-)
