Some 2011+ Dodge Durangos and Jeep Grand Cherokees came equipped with automatic self load levelling shocks called Nivomat shocks. These things create all kinds of weird handling problems when they fail. Normally when a vehicle has some kind of adjustable ride height suspension you'll see air springs or at least electrical connectors on the shock. Not so in this case. It's all self contained in the shock absorber unit. They are VERY expensive to replace but they CAN be replaced with a standard shock. You'll just need to purchase a standard shock mount as they are different.
The Nivomat shocks are fatter and if you can still read the label you'll see the manufacturer's name Sachs. If your vehicle has those and has any kind of mileage or age then get rid of them! Get yourself a standard shock! Just don't forget to get the standard shock mounts as well. You will notice a major improvement!
