Ive got an 04 L90E that just came in from auction. There is a leak from where the drive shaft and tranny come together. Have yet to dig into it but Im hoping it is a seal. Anybody care to chime in on it?

Stopped by the welcome thread. Thank you. I have attached some pictures I took real quick to show the leak.

On the outside
There should just be a seal in the bore riding against the drive flange. As long as the bearings are tight and the drive flange is OK it should just require the seal.
Torque on the drive flange nut is 442 lb. ft and the driveshaft bolts are 89 lb ft

You're going to need the seal, and O-ring in second pic #20. Part no 21 has 2 different parts, get both. That's for locking the flange nut. If you're careful, you can reuse snap ring 23. Drain the oil before performing the job. I always recommend replacing the bolts and nuts at the flanges. They never tighten properly. Use care when separating the flanges, if you damage the slots, it will be very challenging to reassemble.

Do you have the complete parts list for both photos by chance? That will help when ordering the parts.

Parts illustration with parts list below
I incorrectly highlighted the wrong screw in propshaft . It should be the one facing right into the flange with no nut. #5
