I recently got my brakes hot on a long 13% grade in BC. I noticed I had a small gear lube leak at the axle flange.

First, can I just remove the nuts and pull out the axle and replace the gasket without any special tools?

Second, what is the foot pound torque for the nuts?

2013 3500 with 42,000 miles.

Thank Larry

2007 was the last year a hard copy Sprinter Service Manual published. Only 12,732 pages. Can be found here. Many stuff carries forward.

I am "Geeking-out" on the DPF...er...PDF. Looks straight forward, no special tools.

No special tools beyond a Nm torque wrench and the Hylomar sealant.
As suspected there is no gasket.
Has the OP checked the torque on the axle flange nuts?
If tightening the 6 axle flange nuts does not seal the leak, you can remove all
6 nuts, and pull the axle out enough to clean both the axle flange and the hub flange
then reapply the Hylomar and torque to 20 NM using a crossing pattern in the 6 nuts
then tighten to 40 Nm.
Hylomar normally does not "go away" even if the hub was overheated by the
brakes, so it may simply be that the axle flange nuts are not tight enough.
You can get Hylomar at the dealers, and some big box auto parts stores have it.
There is a Permatex imitation Hylomar that's also available.
Also check the differential oil level.
There is not supposed to be very much gear oil out at the hubs, just enough to
keep the hub bearing lubed, but not half way up the axles.

Thank you Bob, Mike, and Roger, exactly what I needed. Just to make sure the 40Nm torque is approx 30 foot pounds? Sure seems like a light torque. I'm pretty sure I over torqued them on the road trying to get ride of the leak. Was just using my 1/2" drive with the breaker bar.
