New Eaton Locker added to Base H3

[hummer.h3]

Hi guys, Please need help!!!!, I also seen the elocker on trailduty, I was under the impression that rear diff on my h3 hummer was a 10 bolt 7.5" and not a 8.5" Did the dealer have to do anything special to fit the Eaton Locker. I want to buy this locker but I want to be sure it fits.

Thanks

Is there an upgrade path for the front alum diff after the rig is out of warranty?

A lot of people here are hoping to upgrade the aluminum case to the cast iron one from the 08 alpha. The gears are different, but any good shop could set up your old gears in the new case.

I wonder ... since it's all GM, it might not void your warranty either. But if you let a dealership do the work, you'll at least get their standard 1-year on parts.

No the dealer didn't have to anything special to make the locker fit.. The Eaton Locker I ordered from Trail Duty had everything required to hook it up... I even had them locate the on/off button for the locker where one of the factory light buttons would go... Very clean... If you need a picture let me know....

Got it back from the dealership today levelled and locked .
Will try some climbs tomorrow to see how it works.
Here's what I was charged (don't know whether it was reasonable or whether I got takened to the cleaners )

Part# Part QTY List Sell Total
009418390 Bearing 2 114.84 76.08 152.16
089021677 Gear Lubr 35 29.72 23.72 71.16

Interesting that they put the button on the auto-shifter console and not use one of the buttons available under the radio. But the yellow button does look cool next to the shifter.
