2dhs87 Posted December 7, 2009 Report Share Posted December 7, 2009 what needs to be done to make my 02 dhs ride better . are their any shocks or is it all air ride? Link to comment Share on other sites More sharing options...
Cadillac Jim Posted December 7, 2009 Report Share Posted December 7, 2009 The rear shocks have an air pressure adjustment to level the car that does not affect damping. The damping is electronically controlled. I suggest that you check the tire size and air pressure recommendations on your door jamb and make sure that your tires are the right size and aren't overinflated. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

Cadillac Jim Posted December 7, 2009 Report Share Posted December 7, 2009 My shocks and struts have over 140,000 miles on them and they are fine. Your mileage may differ. If the rear is "bouncy" then the shocks are likley gone. If the front end is "bouncy" then the struts are likley gone. If you don't see shock oil leaking out for some time, take your time before you decide to replace them. Electrically controlled shocks are expensive. I was assuming that your ride was too firm. Hard tires can tell the electronically controlled suspension that the road is rougher than it really is, causing it to tell the shocks to stay on the stiff side nearly all the time. If that's the problem then you might get your ride back by keeping the tire pressure within a few psi of what is recommended on the door jamb. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

Cadillac Jim Posted December 8, 2009 Report Share Posted December 8, 2009 The first thing to do is to look for codes. If you have a suspension or RSS code then the electronic suspension control, which stiffens your shocks temporarily when you hit a bump, may not be working. Clikck the link in my signature block for instructions on getting the codes, then post them here. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

Clikck the link in my signature block for instructions on getting the codes, then post them here. i ran a diagnostic for the codes and didnt get any rss codes. my car either never registered the r.s.s. or never checked it in the systems test administered through the dash read out. i went throught the test cycle fw and rev. and never got a rss test for that sys. there were other codes but most of them were past codes not current. the only codes that were current were a few in the seat mem or some thing like that.
