the front axle seals are fairly easy..
-DRIVER SIDE-
-take off wheel
-then remove the 6 bolts around the cv shaft/ axle shaft
- using a rubber mallot hit out the axle shaft itself.
-once the shaft is out the seal will need to be pried out (it will still be on the truck) i used a screw driver. not the smartest thing to use but all i had.
-once out just replace with new seal and put everything back together.
-PASSENGER SIDE-
-take the wheel off
-remove 6 bolts from cv shaft and axle shaft.
-then remove the axle shaft tube that connects to the front diff. (i dont remember how many bolts) but i believe its 5 or 6.
the bolts in the upper right of pic.
-becareful when removing the tube so that the inner pieces dont fall out. (they did on me, but i just youtubed how they went back in)
- you should be at this point now
-the seal is facing up in the picture, so you will just need to remove it.
-once new one is installed just put back together.
i dont remember what size bolts they are. i almost want to say 11 or 12 but at the same time that seems wrong to me. each one might have taken me an hour, but thats mostly because it was the 1st time ive done them so it was a learning experience.
hope this helps some. good luck
