do I need new shock absorbers?

if its sitting crookid your going to want to look for (if air shocks) as was mentioned leaking lines or bad fitting, sprung torsion bar,weak leaf springs,broken leafs , broken shackel, air pressure in your tires of course,and so on and so on.


sprung torsion bars , broken leafs, broken shackel these sound like they should be obvious...
anyway of identifying a weak leaf spring.
