    Hey everyone-
    My right front spindle assy has been pretty moist lately. I'm guessing it's the axle seal?? I'll look into it further before I fix, but, my question is this. How difficult is the seal replacement? I've had the calipers and rotors off before, replaced my manual hubs, replaced the wheel bearings, etc. Once I get to that level of disassembly, is there a whole lot more to get to the axle seals? My Chilton manual seems a little vague, and it doesn't LOOK that hard.... INPUT??

    Actually once you get all that out of the way you just undo all the bolts in the spindle and the axle will come right out. Once both are out, remove the pumpkin cover. The seals are inside. Word to the wise, clean out the tubes while you are at it. Look the axles over good, especially where the seal rides on it. If there is much of a groove, sometimes replacing the seal does no good. You might have to replace the axle in the worst case. Good Luck...

    Good answer but... he didnt go far enough. You have to pull out the diff carrier to change them. They are a major pain, I did it once on my last truck and I really dread the day when I have to do it again. This is a GM10 bolt that I did so it may be different but they were near impossible to get in straight, they are set way back in the tubes so a regular hammer wont cut it, you have to develope a method of holding it straight, putting a pipe or something the size of the seal and hitting that. It wasnt easy by any stretch. After lots of cursing and throwing stuff, I did get them done but...... Good Luck! [​IMG]

    If the noise is coming from the spindle area-it's probably not your axle seals. Do you have fluid running out the diff tubes? Is there fluid in the diff.-check to see. pull off spindle and check axle bearing that's inside the spindle-if you just repacked the hub bearings last time-then this is probably where the noise is coming from. Replacing the axle seals inside the diff. is a real pain.

    I wonder if GM has some cutsey special tool made just for putting the seals in, like a small hydralic ram that uses a boss the size of the seal and just powers it in?

    And where did the noise factor come from???????
