    Default Front axle woes. Repair, replace, or ?

    Have leaking seals and growly bearings on the IFS front axle on my 1997 k2500.

    I'm not sure I'm a good enough mechanic to rebuild it. Are there places where you can exchange them, or should I take it to a driveline shop, or what?

    I am in the same boat as you. I have done it all. But, gear work scares me. I don't mind messing with a rear end in one of these trucks, but this split case front diff is an entirely different animal. I have seen guys set them up wrong and have the case explode. Mine is at the gear shop as I type. I have a bad carrier bearing and a bad bearing in the axle tube. If the gears are good I am looking $650 rebuild. That is all bearings, seals, setup, and remove and replace. I actually found a place in Maple Grove, MN that I considered buying a reman diff from, they wanted $750 for a completely rebuilt unit. I don't know how close maple grove is to you, but they may rebuild yours cheaper than their already rebuilt one.

    on another note, I would not buy a used one. (not rebuilt) The warranty company put the one that is in my truck in it last year. They claim it came from a truck with 60,000 miles on it. Well, a year later I am in the same boat, just with an expired warranty.

    Yep, I did the rear axle seals on mine, no big deal at all. But yes the split case front requires much more disassembly and there is all kinds of opportunity to make expensive mistakes. There's some stuff I'd rather send out and this qualifies.
