Need a new H2 Front Differential and help changing it.

HUMTECH - -thanks for that point re: servic 4WD. Given we were on the rd. we pulled out the trusty manual and as you point out there was no real urgency in re: to the front diff.. just "you can clear the DIC and have it serviced". We added about a quart of gear fluid because paranoia has set in from the first blowout (good thing my Man used to replace front diff.s for a living!!). But I take difference with too much maintenance - it is too much $$$ coming out of my pocket for an expensive, high profile vehicle with less than 65k miles. To that point if there is also some electrical problem well just add on the bucks. But! The check engine light is a bit flakey and the clock resets when the gas is too low. I will be sure to bring that point up as well. But still .. if you all out there see a pattern with front diff. problems don't be a sucka.. call GM on it.
