Slid over a curb '88 S10 2 door
 

Not sure what I messed up but when I hit a bump or hole I hear something banging/knocking in the rear. I got her up in the air today but did not see anything broken. I am thinking either the leaf springs or shocks are bad. Anyway to tell which ? Bounced on the rear bumper. It did bounce some. The truck has about 85K and the leaf springs may have been replaced before because it is not the original rear axle per a mechanic.
