You can Select Your Vehicle to check if 7L1Z-4R602-B fits your vehicle.

Driveshafts have a "slip yoke" at the front end that inserts into the extension housing of the transmission or transfer case. On two-piece rear driveshafts, a center bearing supports the driveline. The rear end of all rear driveshafts connects to the rear axle's differential pinion flange using a flange yoke with four bolts. Front driveshafts on 4WD models may have a slip yoke at either the front or rear end, depending on the vehicle type.

Remove the front driveshaft shield. Mark the relationships of the driveshaft to the front axle differential pinion flange and transfer case output shaft companion flange. Remove the attaching bolts. Lower and remove the front driveshaft. Inspect and replace the differential pinion seal and transfer case output shaft seal if needed during removal.

To install, follow the reverse procedure, ensuring proper alignment of the marks made during removal. Tighten all bolts securely. For two-piece driveshafts, check the center bearing during reinstallation.
