Level my bird,

For some reason, the front of my bird is higher than the rear. Being that I don't know anything about this car. Is there air supension on this and if so how do I put air in it to level it out.

If that is not the case I need to replace the rear supension. What is best product to use for the new suspension

I dont know if the year makes a difference, but my 1996 had air shocks in the back. If your shocks are bad, then you need new ones. Also, do you have anything heavy in your trunk like a big subwoofer box?

thunderbirds never came equipped with air suspension. mark viiis had air suspension, however.

as for the suspension, your best bet is to go with an aftermarket lowering kit. eibach makes a 1.25" kit that'll see the profile of the car much nicer, and it'll be a hell of a lot cheaper than going with OEM replacement.
