I am having a leak in the front axle of my ext o3. I have hit a rock a time or two but I can detect no cracks. It looks like its leaking out of the left seal of the differntial. I dont know if they will warrenty it or not. Is this a problem anyone else has had? And how hard is it to fix? Is there a product like barsall you could put in the differential> Thanks nomad

My left seal on my front diff was leaking too, unknown to me. It was fixed under warranty.

Unless the case is cracked is should be repaired under warranty. :)
