Warble, differential
Hey All,
In my never ending "rings of shame" saga with my Corvette (a new service tag ring added to my fob each time it is at the dealer for service), the differential cover was replaced per the TSB to solve the warble problem. The result is that the warble is worse/different, and perhaps a more persistent droning sound from the backend. So... no luck...
The dealer (who I am very happy with so far) has now suggested changing the differential. My question to the group (and to hopefully make me feel better/confident about this situation) is have you had a differential changed? For the warble issue? Were you happy? Any concerns that I should be aware of?
Thanks!
Jason
P.S. on a positive note, the change of the lifters due to AFM failure seems to be nicely solved, and the triple-flush of the transmission seems to also work nicely (I only drive in Manual mode).

The differential cover houses a bushing instead of an actual bearing. No problems with replacing a differential as long as you have a good mechanic.
I do believe the manual trans. and auto trans. cars don't use the same differential.

I gave up and got rid of my '16 base Stingray with A8 over the "warble issue". Traded it in at a fair price on a '19 M7 and never looked back.

Warble
B Jones helped me identify the warble in my new 2016 Stingray. Between emails to the GM CEO, a great dealer and Jeff Strausser of GM my entire diff was replaced and the problem was solved, at least for my car. I also added a Range device which has been it to this day.
