Thats doubtful. The H3 has a GM 4L60E transmission.

edit: Whoops, I don't know about the manual transmission... They could be the same.

That does not make me happy. I still have not been reimbursed from my dealer from the April failure.

Besides, I don't do "waiting" well

Is your H3 a daily driver or your toy? If a toy, WTH, why not consider a straight axle swap and get rid of the IFS altogether in the front? Someone has to be first. Though the can of worms that would open is pretty big.

Did they replace your case last time or just install a new R&P?

[Desert Dan]

Would a Cast Iron or thick steel cover on the front diff help with any of the flexing??


Also the manual tranny in the H3 appears to be verey similar to the one in my buddies Toyota 4 Runner?? -!-
Some ting wong

No they did not. Just the ring and pinion.

Don't worry, the FJ will start busting junk too when someone starts wheeling it hard enough.

[lllateralus]

Well, it didnt sound like he was wheeling it hard... AT ALL.

And the FJ is and will be a typical toyota 4X4. Bulletproof for a few hundred thousand miles or more.

(and many FJ's out there have been wheeled quite hard... but im sure you are well aware)

[NEOCON1]

we see alot of the 2 wheel drive models out there bulletproof ?

I'm assuming you got pre-authorization from the dealer or Hummer before the repairs were performed in Moab? If so, who gave the authorization the dealer or Hummer assistance? Let me know, I might (and I say only might) be able to call someone; especially if the ok for the repair came from the assistance center.

As for the front diff; AAM makes a cast iron 760 axle, that is supposed to be identical to the aluminum axle currently being used on the H3.


I believe somone asked about the manual trans, the H3 uses the Aisen AR5, and this could well be the same trans used on many other vehicles.

[HummBebe]

I called my dealer from the trail, they said they would send parts. The parts were ordered from the Salt Lake Dealership. I spoke with them. No one asked me to call the Assistance Center. Neither my dealer nor the Salt Lake dealer.

Neo's items were fully repaired, they were authorized to cannibalize a new truck to repair his. They covered everything fully.

My dealer asked me to pay for the parts and bring them in when I returned from Moab. I did.

My Service manager said he needed to speak to his rep first (I'm assuming the GM Warranty rep?). I recieved one phone call about two weeks ago telling me they were still working on it.

My service manager did say, he did not see any problems with being reimbursed, however, it was on April 21st that the breakdown occurred. No one has called since.

I don't know if you can help, but any assistance would be welcome and greatly appreciated.

Yea, Toyota's are bulletproof. Tell that to a friend of mine who had his Land Cruiser towed off the White Rim Trail, outside of Moab, a few years ago. Lucky he had a tow strap. He didn't hit anything, and for those who have traveled the White Rim Trail, know there is nothing he could hit to damage the vehicle. However, his trans grenaded for no apparent reason. Toyota paid the tow to Grand Junction, and replaced the trans without a whimper, so that is good.
My ex-girl friend in TN, had a Toyota Echo, and that was the biggest piece of S**t I have ever seen. It spent more time in the dealer than any car I have ever had (except for my wonderful Caterra ), and except for a few Jeeps, all my vehicles in the past 15 years have been GM.
I'm not saying Toyotas are bad, just have a problem of people implying they never break. Anything man-made can break.

I can't interact with dealers, I was hoping the assistance center had gotten involved. What I would suggest is to call the dealer and ask why he has not reimbursed you for the claim. If there is a problem with Hummer, let me know; as you probably already know, I love busting the chops of the Hummer Brand Quality Manager, and I have no problem emailing him to see if he can help get this solved.
If it is a problem with the assistance center, I can write an old friend who is in charge of the Gm assistance center in Cambridge Ontario, and the Saturn Assistance Center in TN. He may not be directly in charge of the Hummer center in Austin TX, but he should have some contacts. Besides, he is a Utah boy, born and raised in Utah, and then went to work with GM. So he might appreciate the H3 failed in his old home state, Utah.

Let me know, you should have my email address, if not, just PM me and I'll help all I can to get you your money back. Can't guarantee anything, but possibly I can help.

So if the AAM 760 is identical that sounds like a good alternative (assuming all the mounting points, gear ratios etc are the same). Does anyone know what the 760 was or is currently used in?

http://www.aam.com/technology/tech_prod_dl_frontaxle.html

I checked their web site and they don?t list a 760, just a 725 in aluminum or iron and a 763 in iron which looks different in the picture.

These guys look like they might know Cool site.

[ketcat]

Thanks I may call them. I am very interested in finding my options. I go four wheeling with the wife and kids so reliability is the highest priority for me.

[f5fstop]

Sorry, meant the 725, why I typed 760 even amazes me.

Did anybody else noticed that these guy's have a bunch of locking differential that are compatible with abs and traction control systems that can be turned on via a user. I will admit that I kn ow very little in this area, but could we not get them for our front locker?

Thanks for all your help.
