Repairing the V8 Ambo propshaft.

This is a continuation of the Thread 'Encased Driveshaft' here
http://theamcforum.com/forum/topic88313_post790329.html#790329

The shaft and torque tube from my 63 Ambo V8 auto are at the repair shop.
But after a week he hasn't even got it apart yet.

Need some advice please:

I'm a bit stuck because I lent him my TSM so I don't have it to refer to and I don't know if he's misreading it, but he says that before the shaft can be pulled out, the female part of the rear slip joint has to be pulled off the axle end, and he has to make a tool to do it.

He also says that there is a clip holding the centre bearing, and he can't get at the clip until he pulls off the female end.

This chap is a prop shaft specialist and no fool, but he's never seen one of these before.

I thought the shaft just pulled out of the front, complete with the female end of the axle slip joint. And no clip.

Don't want to damage it. Can someone please confirm?

From 64 TSM, A "slip" or "union" type coupling is used. The propeller shaft and coupling can be slipped off the pinion shaft when breaking the connection between the propeller shaft and rear axle.

They use a special tool to remove the pinion nut so your guy will probably have fun with that. I was scared to get into that part of it and settled on just a carrier bearing change. 

When i repaired mine it pulled out by hand through the "front". Did the internal shaft rotate freely when you removed the tube assembly? Maybe the centre section is stuck.

The oil most likely came from the trans rear seal. That also causes the rubber to disintegrate over time. A little just leaked into the tube. The yoke welded on the two piece shaft isn't surprising -- probably WHY it's a two piece shaft. With cracked yokes they will need to be replaced. I'd just go with a single u- joint, which will require lengthening the front tubular portion. That should be easy for any driveline shop. IIRC the yoke has the same splines as a T-10 manual trans, but check! If the shop can't find a yoke that fits let us know, someone should be able to find one over here. The 67-71 AMC V-8 M-11/12 yoke may fit, not sure if they are the same as the older trans or not.

Well, oil in the tube has never really been a problem, even with a leaky trans seal. It will leak out around the rubber cushion up front. But a 3/16" or so hole just in front of the center bearing wouldn't hurt. That's all I'd do -- drill a hole. Won't get enough dust in to make much difference, especially since you won't be driving the car every day.
