The YJ heavy-duty telescoping shaft assembly is similar to the CJ with two precision needle bearing u-joints and a vibration reducer. A vibration reducer was standard on YJs but A version without the vibration dampener is also available. The OEM steering shaft assembly was not designed for the added stress of lifted bodies and oversized wheels and tires which cause premature wear.

Borgeson manufactures a direct bolt-in heavy-duty replacement shaft assembly that includes a slip shaft, collapsible shaft and precision needle bearing u-joints. The steering shaft assembly is easy to change with common hand tools and will improve steering precision.
