Specifications: 3.5 in shaft diameter · 0.083 in wall thickness · 92.625 in length · slip yoke (end 1) and universal joint (end 2) · greaseable · overall length adjustable · standard replacement grade. Package contents: one driveshaft. An axle nut and CV joints are not included.

The rear driveshaft carries driveline torque to the rear axle. It may need replacing if you notice any of these signs: vibration that builds with road speed, a clunk when shifting into gear, or squeaking from a worn U-joint. Tires, mounts and axle components can cause similar symptoms, so diagnose the cause before you replace the shaft.
