Rear pinion seal maybe? Pull off your diff cover to confirm and throw in some good synthetic while your at it. Check the fluid level in your transfer case also.
the rear pinion seal is on the end of driveshaft that hooks up to the differential right? what do i need to replace this just the seal? Also until i can get this fix will anything brake if i continue to use the truck? the diff. still has fluid init. thanks
