If the performance of your Jeep's steering and handling is noticeably degrading to the point you feel unsafe, or if you have added larger tires have heavier duty components, you may very well need to replace that steering box.
While normally a pretty durable factory part, harder driving over time or more rugged off road driving, can adversely affect the box. Plus, those larger tires on the vehicle can make it more difficult for that part to perform. So, many upgrade to heavier duty boxes designed to apply more force while turning - making it tighter and more accurate. Quadratec also offers factory, and factory-type, steering box replacements as well as many of the needed accessories like braces, mounts, seals and more.
