ATTN: H3 Brand Quality Manager

[ROX]

I don't mind. In fact, I hope GM is reading. This is a Hummer Board, and this is where their consumers meet and discuss issues involving HUMMER. This is one topic they can no longer ignore. I look forward to hearing their response...

I think the issue of the the diff breaking should have been addressed ealier in production. Hell, I had mine replaced along with the transmission and it had only seen a couple of moderate trails and one 1200 mile road trip.

Also something for the HUMMER reps to keep in mind is that HUMMER owners will add and upgrade parts!

The addition of 35's, a "ton" of accessories, recovery gear, tools, passengers, and a poop bag is just too much for these H3's apparently.

I understand the extra stresses of adding the weight and larger tires!!!! I do. I have added this to H3 and had issues. SO have a few others that I have talked with. I have added larger tires and wieght to SEVEN H2's and only had one tierod issue.

I hope beebs upgrades to an H2 now! She's had wayyyyy too many issues on the trail with that front diff.....along with many others.


Out of curiosity, how many have blown a diff on their H3? DId you have the stock tires or larger? Maybe a list would help those looking in on our forum. Other than the dealers, wher else can they get "constructive" feeback from many owners at one time?

..poor beebs.

+1 to those that helped with the recovery!!! It's great to see other group help out in a time of need.

Thank you Tim, but just to clarify a couple of things:

I personally have been strapped for several hours off a trail ONCE…Golden Spike- April 2006. (8 teeth off the ring gear, chipped pinion gear)

I have broken the diff case shortly after in September of ’06, but my vehicle was drivable. (It broke because of the “carrier” bracket bushing wearing, which allowed the prop shaft to slam into the back of the diff when I put it into gear thus cracking the case and chipping the pinion gear, again.)

Many hypothesized that it was because of the 35’s….it wasn’t. Folks with 33’s were doing it too.

How many H2’s with 37’s pop front diffs? None. It’s just not a viable analogy in this case.
If it was due to 35’s, for as many diffs that have been changed out, GM/HUMMER would have said….those with 35’s do not get repaired under warranty. They haven’t done that, because they know, it’s the aluminum case, not the tires.

The Engineers run 35’s on their trucks, Rod Hall runs 35’s on his personal H3.

It’s a non-issue here. It is simply cause by too much torque and an Aluminum housing.

Aside from this trip, EVERYTHING I have broken was prior to adding the off road gear, winch, poopbag included, to my H3. I have made many modifications to support the weight added. HD Torsion bars, very nice shocks, leaf springs, etc...

I still made it off the trail with a broken locker, t-case and winch. I drove all the way home and then to the dealership.

I just don’t want to have to wait to wait for it to break again, get strapped of a trail again, and then have to partially pay for an upgrade THAT SHOULD HAVE BEEN DONE IN THE FIRST PLACE.

dammit.

Well said HummBebe! Just like they decided to put the 3.7 in all H3's, they need to man up and put the cat iron diff. in all H3's.
