ESOF problems
I am new here as I just bought my first SD, and I have read through all the threads on ESOF but still cant find what i need.
Truck: 2000 F250, 7.3, 4X4
My auto lock hubs will not lock into 4X4 automatically. When I manually lock them they work fine. I tested the vacuum on each hub with a hand pump and gauge. I connected the hand pump directly to the nipple on the hub. The left side held the vacuum fine. The right side would not hold any vacuum, the gauge just read 0. I switched the hub locks and still no vacuum on right side. So, it seems my problem is in the actual RH hub bearing assembly. I removed the right side hub assembly and I can now see the large knuckle seal. I am thinking that this seal is my problem, because i read that this fails most often. I cant figure out how to remove/replace this seal? Anyone have a link? Comments?

Yes, I have seen this on Guzzles page. My problem is not with the auto hub locks, it's with the hub bearing assembly itself. I need to replace the seal between the steering knuckle and the hub bearing assembly. GUZZLE refers to it in his article about replacing the needle bearings, but doesn't show how to replace this seal.
