He says he never came across this problem in the 20 years he's been there. That they just stop making a part, but said the 04-up is different an won't work after lookin at the demensions. I can't possible be the first person in the world to come across this problem an someone has to make this. Anyone that can help here is appreciated greatly. Thanks.

If it is item #7 in the above link, then the part number shown is for all years. Check the link below which shows that part number for all years. The front diffs are the same except the gearing which changed in the 08 and 09 trucks.

Called that place talked to a travis at nalleygmc said 03 part #7 in description is different from other years, actually was kind of a dick on phone when I asked him what am suppose to do. Says 03 was a specific bushing.. Believe me I'm willing to do anything at this point but 3 ppl now told me it won't fit..

The front diff carrier is the same from 03-09. With that, I would think the later bushing part number 88963599 would work on it. In the GM catalog, they don't specify what the difference is between the two bushings.

I really think they didn't update the part number. I've not hear one person in the 5 years I've been on these boards mention 03 front diff being unique to any other years.

You need the part, if it doesn't fit your last option is junkyard.
