1991 Suburban springs, questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Our half ton 4wd Suburban has some suspension issues. It just sort of wallows down the road with perceptible body roll not really correlated to cornering, like it's not really sure which way it wants to lean. It doesn't wander but it just feels squishy and unsettling. It didn't used to be this way, and the several other solid axle 4wd Chevys that I've owned were always solid handling.

It has new shocks, new tires ( LT235/75R15(C) @ 45psi ), and I took up a little bit on the power steering box adjuster a while back to take up a little slack. It goes where you point it, but it feels more like a boat than a truck.

I'm thinking the rear springs are wore out and in fact it has a static lean to the left rear. Does that make sense or could there be something else causing this issue?

Does anyone know if 73-87 3/4 4wd pickup rear springs will just bolt in ???
