In the Underhood fuse box of your 2008 GMC Sierra 2500 you will want to check the following fuses:

1- Right Trailer Stop/Turn Lamp
3- Left Trailer Stop/Turn Lamp
6- Trailer Brake Controller
10- Trailer Back-up Lamps
25- Trailer Park Lamps

You can use a circuit tester like # PTW2992 to check the fuses without removing them. Power on the top of one side without power on the other side means a bad/blown fuse.

Hey Mike, yes because both hubs are for 3,500 lb axles. That said we don't carry the 8-247 so best option would be the #8-247-50UC3 or any of the other hubs at the attached link on this page.
