I just picked up a 98 nissan frontier. I love the truck its my second nissan P/U. Only thing is this one seems to be leaning on the right side rear like 3 inches. Is it a bad leaf spring or a bad shock. Since i just bought the truck im kinda broke to take it to a mechanic. It kinda floats in the rear (Up and down a little) when hitting bumps. Any help would be much appriciated.
