I'm having some fun w/ this one... The jeep is a '90 xj 4.0 5-speed 4x4. The problem is when i start the engine there it a loud hiss coming from the rear end. It sounds just like a leaking air hose or punctured tire. the jeep is basically stock with about 3-4 inches of lift, so there's no OBA or vacuum back there. Has anyone dealt with this before?
