Gmpartsdirect finally got back to me on the correct part number for the front hub on my 2002.
Browsing their online catalog shows that the part is 15056760. The dealer told me A9059060 (they looked it up on vin).
Well, the word from gmpartsdirect customer care (using my VIN) is that the original part number was 89059060 but has now been replaced with 15225753.
Lo and behold, 15225753 does indeed pull up in their system. However, it is a special order item, but the price is $145.46 which I think is quite reasonable since it includes the wheel speed sensor and 8 studs.
I'll pick up a new axle nut as I understand that should always be replaced. Other than that, is there much to this job?
I'm thinking it goes something like this:
1. Lift truck
2. Remove wheel/tire
3. Remove hub extension (only applicable on 3500 dually)
4. Remove brake caliber
5. Undo axle nut
6. Undo 4 knuckle bolts and remove hub
7. Reverse procedure with new hub using the torque values below
Hub nut: 177 ft. lbs.
Hub extension nuts: 96 ft. lbs.
Hub to knuckle bolts: 133 ft. lbs.
Brake caliper mounting bolts: 80 ft. lbs.
Does that sound about right?
