    I already posted this in the LT BS thread but figured I would post it separate for others to see.

    As I was leaving for work this morning I noticed a small 6" puddle under the truck.

    I popped my head underneath to see this

    I'm not sure when it happened but it must have started a day or 2 ago. I checked all the bolts to make sure they were right and was able to service it with 50-100ml of oil. Pretty sure I tweaked it offroading. (I hit 10 miles of trails to work everyday and jump it and beat on it everyday) it was enivitable.

    Anyways I will just be keeping an eye on it and filling it for a month before I swap it for a 9"

    Check to make sure your differential breather isn't blocked.

    On top of the housing. IMO a breather won't cause that. I'd just pull the diff out, clean off the gasket, and re-seal with some grey or ultra black RTV. Good time to change the diff fluid too. :p

    i didnt think so either but it wouldnt hurt to check it out to slow the leakage for now.

    I really think i tweaked the housing somehow im sure i can reseal it but im not sure if something else is going to go out with it being tweaked or bent

    You might have just flexed the housing enough to break the seal.

    I'd hit it with some brake clean and see if it comes back.

    In the LT topic didn't you mention that one of the studs is bent? That means you impacted something on the trail and ultimately caused the diff to leak. If that particular stud spins while trying to torque or unloosing the nut you will have to cut it off and replace the stud. Not too hard to do but it takes time. Besides the bent stud..its a common issue for our diffs to leak at the seal. The torque and power from the motor will naturally make the studs to come loose over time. I use red locktite on my studs and I torque them to The recommended torque values at 18ft lbs /25nm as stated in the factory service Manuel.

    I didn't notice any studs bent it looks like the gap on the lower housing is way more than the top. Almost like the housing itself is bent
