I realize this is forum is more geared to lifted and off-road suspension, but there isn't any regular suspension forum. So I thought I'd ask here. I have an 01 Suburban 1500 with Autoride, and I have the "service ride control" message on the DIC (though it's not always on). Pulled the codes C0585 and C0660. I was told by the mechanic who pulled the codes that both rear shocks were shot--I believe he was referring to the airbags as being blown out. If I get the $330ish shocks on Amazon, will that fix the codes and issues? Codes mean bad left rear solenoid and bad level exhaust valve. Thanks.
