Any thoughts on how to replace the seals in the front axle on a 2001 3500 4x4
The driver side is leaking gear oil by the axle . Thinking about resealing the whole unit

 

go to pg #6 in this section find change frot hub by dmaxtothemax he has a great post on this. I' ve changed my hub like dmaxtothemax states. It is no big deal if you have the tools. make sure the hub has no play when you jack up your truck. Grab the tire and rock it side to side and top to bottom. If there is excessive play replace the hub. If not just replace the seal at the back of the hub. Just a friendly suggestion do a (search this thread), most likely someone has posted this before. Good Luck
