D46-170HP seal leak?

So my Dana Spicer (or whatever their company name is now) rears have blown the input seal on the front drive.

The bigger problem is there is a lot of play in the drive line where it goes into the axle.

I'm told that there is a locking nut behind the bearings (if there good )and if this nut has backed of that would account for the play. If the nut is tight and the bearings are good I've got problems .....

Monday's head ache.

Thoughts...?

 

With a build date of 9/07 I would guess I've got the updated ones. The rears have 480k on them and other than oil changes and wheel seals have never been touched..

I've got the seal kit in hand. The bearings are only sold as a cone kit @ almost $500. And none available locally . So I wait till it's apart ,and overnight them if needed...

I believe the adjusting nut issue (update or not) is my problem..... We shall see.
