i am new and i have a 2000 bonneville and i have noticed that the back of my car is riding atleast 8 inches higher than normal can anyone help me with this

Do 2000+ have load leveling? Maybe your'* is out of whack. Pull the fuse, or get a new sensor arm (or get it calibrated).

I didn't know they had 8 inches of travel.

Yes its your ELC (electronic level control), here is a good discussion with pics and a how to trouble shoot for ya. ELC

That'* cool! I didn't know we had this on our bonnies.

You never wondered what that grinding noise was 1 minute after starting your car?

Yes, I did. Please remember that before this car, which I bought used and didn't drive much until this past year, my newest car was a '92 plymouth sundance and the 92' bonne which I only had for six months or so. I still am learning all the bells and whistles. I was really ignorant in general about my car until I joined this forum.

I will say one thing, I really love my car. You guys get me pumped with all the talk of the mods I see in your sigs. I'm contemplating a CAI, better exhaust system, etc...

Heck, just with the pulley and K&N filter I notice a good difference and it'* awesome.
