1999 Grand Marquis body roll and "floating".?

Question

My question this time is how do I get rid of the excessive body roll on this car, also for as far as I can remember(even when the car was new) the car would float its almost as if the factory put the wrong shocks on the car how can I correct this. Any input is welcome, even brand specific. Thanks

Answer 1

Some new Koni adjustable shocks will fix it and if that's not enough, gets a larger high performance sway bar in the front. If there is no rear one, you can add one.

Answer 2

Without breaking the bank, install 4 new Monroe "SENSATRAC" shocks as a first step. I believe you'll find that it steadies the car more than adequately without making it ride like a buckboard.

I also wonder whether that car initially came with the "AIR RIDE" package. If it did, then likely after 14 years,that system no longer holds air.

It is easy to convert to conventional suspension,as above, if you have "Air Ride".

I strongly doubt that you'd need new springs as the factory ones were more than adequate.

With a proper suspension, these big cars are surprisingly agile, not like a Ferrari around the track, but they do have good road manners. I should know, I own two, both have "Sensa Trac" shocks under them.

Answer 3

It's a 14 year old car that had soft suspension to begin with. I have an Avalon, which was soft and floaty, too. Replacing the struts with KYB GR2 struts and replacing the springs made a huge difference.

Answer 4

that's how it supposed to ride like a Cadillac
