You are correct AfterHoursFab
It should not have happened ..... transfer cases should not fail at 66k miles!
Last January, A Chevy mechanic said (about these AWD Equinox's) ==>>>. "AWD Transfer case tend to go (fail) between 50k and 100k miles...."
Like with other issues on these cars,
Such as blown rear main seal in the winter,
Or oil consumption,
gm would probably say "its normal" for transfer cases to fail.
What can we do as owners?
As a preventative measure,
I immediately changed the AWD transfer case oil in my traverse (was at 70k miles) and my 2013 Equinox (was at 30k miles)
And going forward, I will change the oil in transfer cases every 25 to 30k in all my cars.
I try to keep cold tire pressures between 35 and 37 psi.
And rotate tires and align tires at every oil change...
Will it ^ help prevent transfer case failures?
Will it make the transfer case last at least 150k plus miles?
