The hoses in this area deal with constant steering movement and a mix of heat and pressure, so when one piece starts aging, the rest usually aren’t far behind. This kit gives you everything in one go—fresh molded hose, elbow, seals, and the hardware needed to put the assembly back the way it was meant to be.
