Are there hub seals on a dana 30? I know axle seals in the diff. But I'm finding inner and outer hub seals online that I haven't seen on my axle so where do they go? I replaced the hubs with timken new hubs but don't see a inner and outer seal at the hub. Oh and it's a 98 xj.

 

There is just the inner seals at the differential. There are some aftermarket options for the out end of the axles. But since the axles move around a little bit, the seal is never going to be 100% sealed. But it is good to put something there to minimize how much junk can get in there.

 

There are large plastic shields (washers) that slide onto the axles that keep large debris from entering the axle tubes. They are just to keep out dirt and large rocks, but they don't help for submergence in water or mud. The inner seals are supposed to do that. Before you pull an axle, if the tube is full of crap, use a garden hose to flush it out, then change the fluid.

The hubs are a sealed bearing and don't need additional seals.

 

I found this and was thinking Id missed something.
It says spindle hub seal front and rear.

 

Semantics - One manf lists it as outer, and the other calls in inner.
