    I noticed a few months ago that some discoloration around the diff housing. Similar to what a very thin coat of oil would look like. To the touch, you cant even feel it, it's that minute. I showed my dad to get his opinion and he said it was pretty common. Do any of you guys have this? I was planning on doing the dif breather mod tomorrow, would that void any warranty work if I need any later on down the road?

    This last one show's it best, like I said, you can just see it, not really feel anything.

    I don't think the oil stains are anything to worry about. The diff breather mod will not void the warranty if it does not cause damage to the axle/diff assembly.

    With regards to warranty, any modification that causes damage would not be covered (misuse or abuse).

    Brake cleaner is like acetone and dissolves many things including paint. Wouldn't brake cleaner harm the paint on the axle/diff housing?

    Sorry to veer off topic... Yes I live in an arid climate. I feel bad for you folks with salted roads.

    Generally speaking I do think that Toyota could have done a better job on the paint though. It seems pretty weak in and I have seen many pictures with rust... I'm thinking some caliper paint might work well on the axle housing. Haha :D

    I've cleaned mine with degreaser a few months ago when I first noticed it. It stayed gone for a while but I recently noticed it came back when I installed my lift, so it must be pretty slow and small right?

    probably even smaller then you think. Also sometimes you splash a drop of oil that expends and looks like a leak. I would not really worry much. as somebody already suggested make sure nuts are tighten to factory specs. Also what you can check is if studs for those two bolts are at the same height as others. In all differentials studs have bad habit to wiggle them self loose. So check that to make sure thats not the case.
