Driver side drive axle seal seeping

Today I topped up tire air and noticed this seepage on inside dual drive axle tire (photo).

Two months and 1,020 miles ago MOT did full chassis service to include brake lube and adjustment, and 24 point inspection.  If it was seeping then they would almost certainly have seen it.  I have been stationary for 2 months  at current location.

I guess my next step is to check drive axle fill plug to make sure still full to the top (which it shoud be given only 1020 miles since someome was last under the coach and should have spotted any seepage).

I am currently in Benson AZ (near Tucson), and will leave here approx mid April.  Anyone think any issue waiting to get this fixed in either Tucumcari NM or Nacogdoches in mid April (540 miles for one and 1060 miles for the other).

That's a pretty good drip, don't worry about the oil level in the axle. But if continuing to drive with it it will saturate your brake pads, and rotor. IF your brakes got hot enough the potential is there for a fire although rare. Any good truck repair shop can replace the seal. Just make sure they are knowledgeable of Meritor air disk brakes. Not a real pricey repair, the pads can be cleaned and reused.

Check the vent tube on the axle. It may have gotten plugged or folded over.
