Get under there and clean it all up around the seals. Take a good look at what is there and keep the dirt from building up. With care and regular cleaning, those seals will last the life of your rig.
Buildup of dirt and grime is what destroys the seals. The dust seals are there to stop road grime from getting to the oil seals, so keeping it as clean as you can will prolong the life of those as well.
To get under there, you may have to park with the jacks over a dip in a driveway or some other spot that will give you room to get around under there.
If you decide to raise it with the jacks, it only goes to say be sure to use some blocking to protect yourself while underneath. Most likely it will stay up just fine, but is it worth the chance?
Happy Glamping.
