Rear suspension is rock hard, it is like the air compressor has the rear shocks pumped to 100% all the time. Rear of the car appears to be jack high. The slightest bump in the road surface produces loud banging and harsh jolting

Yep, this happens when the ride height sensor go out, here is the location so you can make sure the control rod is still connected to the control arm, (sometimes they pop off) and if not replace the sensor. Check out the images (below). Let us know what you find. Ken
