C6 Z06 Diff fluid change
Any C6 Z06 owners done their own diff fluid change yet?? I have read many posts so far regarding chatter plus the DIY that covers the non-Z differentials. My car was built Jan 24, 2006 and my diff chatters like crazy. The dealer did the mandatory fluid change as the first step last spring at approx 10k miles. It helped for a while but now the chatter noise is back worse than ever at over 18k. Hot or cold makes no difference during parking lot turns. I really don't want the dealer to change out the clutch packs.
I plan to buy 3 qts of the Amsoil Severe Gear Synthetic EP 75W90 and 2 bottles (8 ozs total) of the Amsoil Slip Lock Additive to do my own change. The Z diff apparently drains via disconnecting the pump inlet tube at the diff bottom connection fitting. Some sort of spring clip holds this quick connect fitting together. Is this really an easy disconnect?? Shop manual says that the spring clip should be discarded and a new one used upon reassembly. The manual also mentions a bent screwdriver to remove the spring clip?? Any advice or helpful hints??
Thanks
