Although much improved over the original design, the newer Jeep Wrangler’s steering shaft assembly was not designed to handle the added stresses placed on it by plowing, towing, body lifts, oversize tires, and the popular sport of rock crawling. The steering flex joints will not last when subjected to these stresses and will soon fail. BORGESON has developed a heavy-duty telescoping shaft assembly similar to the CJ with two precision needle bearing u-joints and a vibration reducer that will handle all the torture you can give it.
