Here is a quick tip from my friends over at Memphis Equipment.

Tip of the Month – Remove Inner Axle Seal

To remove the inner axle seal on a 2 ½ ton & 5 ton truck no specials tools are required. Simply withdraw the axle shaft from the housing until several inches of the splined shaft remain inside the seal. Then lightly “pry” the shaft up and down and side to side against the seal and it will pop right out.
