    2007 STS Harsh ride, struts, air shocks

    I have an 2007 STS with the 1SG pkg v-8*. The ride has deteriorated and it feels like no suspension at all. Yeah it's OK on a nice road but that's about it. Car sat for 4 months in heated garage djuring winter, could something have froze up? BTW it has the Magnetic Ride Control. I'm going to take it to the dealer in a few days to see what they say.

    The ride changed dramatically?

    Did you get the car serviced? Some Bozo might have over-filled the tires.

    Did somebody change the MRC ride setting in personalization settings?

    Disconnecting the struts will set an error code and disable the remote-start, probably more.

    The car has 46k miles, no error codes or dic messages. Original Micheln tires(swap out in winter for Blizzacs). I check air pressure all the time. Factory setting is 29lb.

    OEM Michelins are the issue, in my opinion. 5 year old tires are old.

    You're in for some $$BIG money$$ if struts need to be replaced but I can't possibly believe that at that mileage...It has to be something else, no way those struts wore out that quickly...

    I replace one front shock (under warranty) at about 46K miles. I have 65 now and it rides like a sporty Cadillac - firm, but in control.

    Dad 07 went out at 35k my 05 front pair at 39k. Common issue they leak the fluid out and there's less damping. They function but ride is very hard especially over low speed bumps.

    Any way to make an easy check to determine of the fluid had leaked out?

    Dampness around the struts? Or does it make clunk noises going over bumps?

    IMHO, the owner just realized how firm an STS with MRC & 18" Michelins really is. I have AWD, too.

    Buy 4 soft-compound 235/50R18's, run the backs at 28 psi, the fronts at 29 and enjoy the ride.

    Not that I notice and the ride is decent and basically what I expected / looking for. Just was curious about how people can tell. It is significantly stiffer than the F45 suspension that I was used to having. (02 DTS).
