Check suspension

I have a 2000 Lincoln navigator with a check suspension light on. it comes on after driving about 25 minutes. it feels a little out of control. I have had the “o” rings replaced on the air shocks in front. what else can I do, and if I do nothing what will happen.

The light is going off for a reason, it is saying small voice (help me, help me). If you do nothing your continued loss of control feeling will probably get worse.

Yours has a complex suspension most vehicles lack, so you’ll need to go to your dealer.

An out-of-control feeling doesn’t sound safe to me. You probably want to get this checked out by the dealer before you have to swerve around a kid running in front of you.
