who broke the rear axle shaft?
Looks like it got magnetized
Was that on an H3?

To strengthen the LS1 f-body rear ends when going to 4.11's many of us used the ratech solid pinion to replace the crush collar and a diff cover with bearing supports. The problem we saw was that after a few hard launches the crush collar would compress creating slop in the pinion and eventual failure.

The H3's 4.56 ratio pinions are pretty small and there is a large lateral force created especially when in the adv low range. Couple this with some slip-and-grips and the loads get pretty high. Not sure if the ratech solid spacer and diff cover would help with the H3.

Is there an 8" or 8.25 front carrier that would work on the H3?

Even is slight modifications are necessary, that would still be better than the 7.25?

Dana 60's front and rear?

I wish

[HummBebe]

HAHAHAHAHA

Does Dana make a Cast Iron IFS carrier???

OK here is a pic of the latest carnage:

[NEOCON1]

ouch that not good pinion looks awful and it drove home fine after Colorado ???????????

[HummBebe]

It drove home fine, but when I got back I took it in a few days later cause it was making a loud clank when I put it into drive. That's when they changed the Carrier mount/bracket bushings. (Drivline forcing differential up is bad:-)


Then I picked it up and on the way to Deer Valley, I noticed when I got off the gas I would hear a "jingle bells" type sound. Sorta. It got worse and louder over the last couple of weeks, so I took it in and this is what they found. Caput!


This time they just changed the entire case and driveline.

I begged them to make sure I received a new "hardend gear" if possible.

They are also considering (99%) to extend the warranty on the front end (diff) to 100K. I'll know the final outcome of that on Friday.

Once again, HUMMER of Sacramento ROCKS!
