2006 DTS 4 door

Great car and take good care of it but I believe I need new struts (shocks) on front end. Doing 75 on I40 and crossing a bridge it bottoms out with a bang. Only 54000 miles all hwy but I guess that is the way it goes. I need to know what the best replacements are and how difficult are they to install. My other comment is that it rides hard because of those tires that have little air volume. Is there away around that?
Thanks in advance!!:licka:

Does the car bounce easly when pushed down on in the front, also does this have magnetic ride control? Do you have non standard low profile tires?

Doesn't push real easy with a bounce back. Does have those 22 inch thin profile tires. Just how I bouht it new from the dealer. Has that special "computer" control suspension. Hope that helps.
