are they over filling it?
Are they using chrysler synthetic with 2 containers of 'friction modifier'?
good one ziptie.
You are using drifferent mechanics...I would find myself a differential mechanic.
I talked to a differential mechanic and he wanted to move the vent closer to the wheels
Why not find the cause and fix it right? Factory fill on them IS synthetic WITH 2 bottles of their 'friction modifier' If it had regular gear oil in it then that should be flushed out.
