Does your ZL1 Rear Diff moan? Step inside.
Long story short, I noticed my ZL1 making a slight moan when I was going into turns at low speeds and sometimes sharp turns at low speeds.
After some quick research it was what I expected. The diff. gear oil was done and needed to be replaced.
Took the car in to have it serviced and all is good now.
I would of done it myself, but since it is under warranty, might as well let them look at it in case something more serious was wrong.
Does anyone know if it is against ls1tech board policies for posting the Tech Bulletin?
Thanks,
Eric
