Another Center bearing ?
 

Dropped drive shaft and marked it but did not pay attention which side of the bearing support faces the front, any help would be appreciated.

Also, isn't the large nut on the drive coupling be not so tight as this is a "sliding
connection" so as to speak as both ends of the drive shaft are "fixed".

Which Chassis
 

Sorry, 85 500 sel "W126".

From my understanding - based on my W123 experiences - once you've got the prop shaft in place you need to tighten the big nuts. I don't think they are designed to be sliding on the splines. I think any give and movement in that part of the car goes on the rubber bit of the centre bearing assembly.

As for which way round the centre bearing goes... I'm not sure I'll check...

Army's correct
 

The Nut has to tightened to Specs...
But first ,roll the chassis (on it's Wheels) back and forth 10-15 ft.To "Settle" it.

In that link I posted it shows the fore/aft orientation of the rubber bearing sleeve. (Even though it's a W124 orientation applies,Same.)

Thanks to all!

God Bless
