front diff problems
i have a 2006 dodge Dakota quad 4wd. Front diff started humming. Checked fluid and it was pretty low. refilled fluid and the humming is still there. What do I need to replace to make it stop humming?
I would first determine what was humming - the driveshaft joint or the differential. There's a constant speed drive joint on the front driveshaft that has a tendency to wear out.
