Driving with leaking front axle seals?

You know what else was awesome? Hanging out with another Jeep-head, bullshitting and turning wrenches for a day. I know for me (and I suspect for him) it was less a chore to do the work, and felt more like... well, hanging out and bullshitting. We just happened to get some productive stuff done in the process!

This. I already feel like I'm missing out on a fun hang and this thing hasn't even happened yet.
 
The only thing not included in the excellent BFH video is I've been running around on these leaky seals for a year and half-ish. I've checked levels regularly and they were never concerning, granted I'm excited to not have to think about it for now...
