    Hey all. I recently had to pull my trans and t-case due to a broken 4.70 input gear, everything else looked to be in really good shape. Installed the new one and got everything back together. Now I am noticing a chirping sound both in and out of gear when driving. It gets more noticeable the faster I go. Not wanting to blow up my case again or cause any damage, any ideas what the noise could be?
    Yes, there is plenty of oil in it too.

    Just greased the U-joints after seeing a similar post in a jeep forum and drove it again, sound seems to be the same still.
