What did I do?

So I made it to the Moab Jeep Safari this last week and when I left the Jeep was working perfectly. I got home late last night to find this:

Now I know it is a seal leak on the driver's side, but what I want to know is how could this have happened? The bearings and seals on this axle were replaced about 8 months ago with Timken everything. Could a bent axle flange cause this? What else could have caused this? I know someone has dealt with this before so please help me.

Sometimes the seal just leaks with no other damage. Unfortunately you'll also have to replace the bearing and bearing retainer to replace the seal. Smear a bead of Mopar RTV or Permatex Gear Lube RTV around the seal's perimeter before seating the axle shaft.

Thanks Jerry. I just wanted to make sure I did not have some type of other problem with the axle before I replace the seal and bearing. Never thought about RTV around the seal perimeter, but will do that when I replace the seal and bearing.

Did you change your gear oil to a heavy weight like 85-140 instead of 75-90. I went with the heavier weight once and blew two sets of seals before I realized that heavier weight was probably building to much pressure. Changed back to 75-90 and haven't had a problem since then. Hope that helps, that worked for might not be your issue!

Heavier viscosities like 85W-140 are common and completely acceptable without causing seal issues. That's what I run in my axles.
