Hi guys, id sure love a copy of that too! I have picked up a 04 6.0 2500hd and am currently refurbing it to be put in service at our cottage. Would love that if you find it!

hi there hoobie. before you crack open the front diff, make sure you have your parts on hand including enough of that yellow paint with a brush so you can set the preload. The most important thing is that you have the spanner wrench tool for this job. Otherwise you may not be able to set the preload for the bearing after you install a new one. That happened to me. I got all that way and then did not have the correct spanner tool thinking I could improvise. It maybe possible to improvise but I couldn't figure out away. I did as best I could which wasn't good enough and I now have to do the same job a second time after ordering the spanner tool from Amazon. The price for this tool is effing ridiculous. My plan is to use it for my diff and then resell it to others on this forum who need the same one. If I can make half of my money back on the tool that's great, and then the next owner can resell it for the same amount and we can just mail this tool to each other as required. here it is if you are in Canada. http://www.zoneoffroad.ca/tools/spanner-wrenches/yt-a08-spanner-tool-for-gm-8-25-ifs/ here it is if you are in the United States. https://www.amazon.com/gp/aw/d/B0078U9Y3Y/ref=pd_aw_sim_sbs_263_1?ie=UTF8&psc=1&refRID=EDK43E3P40RFXZNFX6B9

2006 denali xl here. i did the same thing. u need a new lock tab, they are cheap at local dealer. unfortunatly u need to buy the special socket tool that sets the preload on the carrier. i *think* there is a needle bearing in the diff case that the driverside input shaft tides through before it gets to the carrier bearing. not sure its name. i think this may be my issue because i still have the noise (only when i step on throttle) and i still have a super wobbly input shaft to the diff on the driver side as you describe. i had this before i replaced carriers and still do after.

isn't this the typical issue where they disconnect the intermediate steering shaft and just pump it like jacking off to redistribute the grease? yes i just said that, but its because thats what its like. i had same issue as OP and took me 10 minutes to do this. i do it once per year. and this, though i didn't pump it full of grease. i just jacked it like vid above. works great. https://www.youtube.com/watch?v=8W7TjXG_BAs
