That's a good question. I believe there's an initial cost AND a yearly fee.

That said...I'm fairly certain that only an authorized GM dealer can purchase the software. I found a copy on the Internet a while back and pulled it down...not the most 'legal' of acquisitions, but neither was half of my mp3 collection.

HELL YEAH FINALLY GOT IT OUT!!! but..... it looks like the spline kinda damaged looks like it got jammed and caused a little indent and the retaining clip looks broke but might not be, should it look like a "u" clip than a "c" clip, but overall I am happy I dont think that little bit of damage will do anything since its the part where the clip goes and it effected maybe 6 of the splines on the shaft portion not the tip. I have to charge my camera and I will post some pics. Thanks agian for everyones help especially Jarek M. since he got like a million emails from me concerning this part. Now for the control arms look forward for more threads for help or emails from me.

Oh one more thing there was NO sealant on the diff when I split it I wonder why that is. The only reason why I was taking it apart was to fix a small leak on the diff. Is that normal? Also what is the best sealant to use for a sealant cause I have RTV Black but I have heard not to use that cause the synthenic oil will eat it up.

[jarek m]

I use the red hi temp one, but the black one is good to.

Hi it is a c" clip if your looks like a u" buy 2 new ones and Differential Carrier Assembly Case Mating Surfaces Sealant GM P/N 1052942 or any good RTV but make sure you read the directions on how long to let it sit before you put the halfs together.

[HUMTECH]

Use a small file and clean any burrs around the c-clip grove and on any splines. This will make it easier to remove again if needed. Use anaroebic sealer on the case halves not sure if that is the part number twr has cause i dont know the part number off hand. If yu use silicone it will push out and eventually leak

[twr]

Hi Humtech, that gm part # is anaroebic sealer, that is what gm uses on the case halfs in the USA, canda has a different part# but same sh-t.

Thanks I have the Permamek Black RTV which I was told is real good so I am going to use that plus stop at the dealer hopefully they have it stock. Is there a part number I can give them incase they are in deiet deiet mood.

Not to stir anything up or anything but since GM is not in the business of making sealant (we found out whats that all about with DIII episode) and it didn't work the first time when they sealed it, why would you expect a different outcome using a GM part#... again.

[twr]

Hi your right gm sealing products are not made by them, they are likely made by permatex or someone else in the business of sealing products. Also you are not stirring anything up. Some parts are machined surfaces and when car companys put things to together at first,[only some parts] they don't use any sealing compond because they think its perfect and won't leak. After being in service for awhile they realized they screwed up and some start to leak. Then it turns into a problem with recalls sometimes or a repair when the customer complains about a leak.

Well iused the Ultra Black cause I was thinking the same thing, It went on good and clean I removed any extra once it dried. Man its a PITA to get the diff in having problems putting it on the jack, but I will get it on there had to go ot town this weekend.

[jarek m]

use straps.

RTV would always eventually leak on my front diff. Had to use GM anerobic stuff to get it to finally stop leaking

[HumminNBoatin']

I used RTV on my diff a year ago. no leaks at all. However I replaced my axle seals at the same time and now one of those is leaking. Its a VERY slow leak just enough to keep the diff wet but no pudling on the ground. What a PITA the H2 front diff is! lol

[lx4life]

Now I have a leak from the top I think its the vent tube, i suspect i filled the diff too much cause this never happened before. I mean it was a lot that came out I thought the diff was leaking then I looked at the top of driver side shock and noticed alot of fluid.

[PaHumBug]

I was just informed that my front axle seal is leaking and that the "axle spacer" from my lift is broken as well. I just bought the truck with a 6 inch fabtech lift. I looked on their website and can't find a replacement part section. Anybody know where to get this part from? Should I just write to fabtech?
