New Eaton Locker added to Base H3

[ChasH3]

Today, the dealer finished installing the Eaton Locker I purchased from Trail Duty.... The rear Eaton locker was $845 from Trail Duty and the Dealer charged $625 to install. The locker is not hooked up to the computer so I can lock the rear diff even when I am not in Hi or Low...The direction says to slow down to 3 mph to engage locker. Also, the button to engage the locker has to be pushed in far to turn on. That it is very difficult to turn on by accident. It also lights up yellow and is very easy to see. Can't wait to try it out this weekend....

Thanks NEOCON1.... I have been waiting awhile to do this... The dealer cost to install is identical to what other off-road shops in the area wanted to charge for the install.. The last thing I need to do now is add some 35" muds....

That is awesome Chas!!!!!!

So you still have the 2:XX t-case, but now you can lock....great job!

Make sure you do a "write up" so we can add to the FAQ.

Yep, no changes to t-case... Just had locker added only... Hopefully, I won't regret it later down the line...

Cool! Now when are you going wheeling with us?

Did the dealer mention anything about the factory warranty? What kind of warranty comes with the Eaton?

Congrats!!! do you know if the 4x4 controls on teh console can be switched out with one that has a locker button and have the locker hoocked up to that? Sewie already asked, but i'll ask again, how does it effect the warranty?

I was told they could not hook up to the 4x4 controls... Waranty wise.. I was told that the warranty shouldn't be effected. Worse case if the locker stopped working I would have to have Eaton fix and/or provide me a new locker (Only One year warranty from Eaton on Locker). Otherwise I would have to buy a new locker....But, the labor to take out and reinstall will be covered. The warrranty will continue to cover anything else that might happen to the rear diff.... Now that said... I did not get this in writing.. But, my dealer has gone out of there way to assist me with any problems I have had with the H3.... But, having the Dealer do the install makes me more comfortable if anything does go wrong down the line....

Sewie, now about wheeling.... are you coming done at the end of April for the Borrego run????? I need to make a run up your way....

[ChasH3]

Now all I need is 35" tires and I can run with BeBe.....

Probably not, unless I pike on the Moab trip. But we're putting together a run up here for the end of summer.

I would get that in writing. If original dealer fixes a damaged axle no problem, he will just hide the fact he installed a locker. However, if there is any type of axle damage to the shafts, seals, ring/pinion, etc on the factory setup, and another dealer attempts to repair, the dealer will probably call WINS and ask WTF axle is this with a locker.
One of the first things a dealer does is pull up vehicle history, and seeing a locker in a non-off-road package will ring some bells. WINS will reject any repair to the axle; IT WILL NOT BE COVERED UNDER WARRANTY. Everything else would be since GM would have no reason to say the locker damaged it. However, the dealer opening up the axle and installing a non-GM authorized part, voided out your warranty, the minute someone at GM finds out.
Believe me, if I was still in the field, and got a call from a dealer who said he had a strange axle with a locker installed and wanted to know if it was under warranty, i would say NO. Why should GM cover it, they didn't make it that way.
If the call just comes into WINS (GM warranty group) it will also be rejected, since the WINS people will probably call us to ask if this is normal. (Again, this is only if another dealer works on it and gets GM involved. If they don't, and talk to the installing dealer, all may be ok.)
Be careful, get the so-called warranty in writing. GM can still refuse to pay, but the dealer can then be held responsible.

Second word of caution: NEVER belileve a thing a dealer representative tells you, UNLESS it is obtained in writing. (Sorry dealership people, but it is the truth.)

So F5 what is your opinion on adding a locker to the Base Package? So far I have had good luck with "Accelerator-Brake-Modulation" and wondered whether the lockers had contributed to alot of the broken front-ends and such as people turn them off or on at an incorrect moment of traversing an obstacle. I mean I have a hard enough time balancing speed, power, gear ratios, and watching signals from spotters without having to remember to turn lockers on & off.

[f5fstop]

Rear locker is great when needed. It it not the reason the fronts breaks. The front breaks because it is aluminum and flexes too damn much. However, from reviewing some charts, the hardening of the gears has helped.

I have no problems with people having lockers installed, I just want them to be careful and understand in some cases, warranty repairs on axle components may be refused.

Hey saw that myself the other day on the Trail duty website. How exactly did you get the dealer to install it? Was it simply "I have this locker, would you please put it on?" or did you have a long discussion. Thanks for the info.

[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?

[Wisha Haddan H3]

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.
