So let me start with saying I've searched. All the threads I find are about the passenger side sagging and that fbodys often had this problem from factory or whatever. Well my driver side sags about an inch or so.

So any time I take a left hand corner somewhat fast (the weight shifts to the right wheel) or when I hit a bump at speed, my wheel has been scraping the inner fender lip. Taking mean slices out of the edge I had some used Koni's in the rear that I figured had started wearing out/the bushings were shot. So I bought some new KYB gas-a-just cheapies for the time being and it's still sagging. PS: I plan on rolling my fenders anyway regardless what I figure out the sag is from

I'm assuming it's my springs, but I just wanted to know if there's a specific bushing I should check first before assuming it's my springs.

 

Sagging is most likely caused by a weak spring or suspension damage, or a bent car. The tire scraping could be caused by the axle shifting due to problems with the panhard bar which holds it centered under the car, and/or over sized tires. and/or wheels with the wrong offset.

 

could be a broken spring I have not hear the f body have had issues from the factory,how big of a tires are you using mine don't even come close to rubing ,but I use low profile tire 17inch

 

Replaced springs. Still sagging. I have 18in wheels with 285/40 on them. Im thinking that my lower control arm bushings are going which would also explain the clunking I hear.

 

sway bar may be bent or weak on one side.

 

big tires ,I would think a good look would clearly show the problem. pictures would help,
