Do you mind sharing how much you paid for the parts? What exactly does it take to switch it out? thanks...

Changing out hubs isn't a difficult job.... having said that, it should still be covered under warranty. The fact that the tires are taller have NOTHING to do with the bearings going bad.

IF ANYTHING, the taller tires have a larger diameter and rotate less times in one mile than a smaller tire.

Based on that logic, the bearings aren't revolving as much as a stock truck.

Just another way the dealer/warranty tries to screw us.

I bought them from Advance Auto Parts. If I remember right I paid like $250 for each of them?? Somewhere in that neighborhood.

Also the Taller the tire the more stress. Taller tires offer more more leverage on the Hub when cornering. Also if you have less offset with aftermarket rims it also causes more stress on Hubs. Think about it you are haning more weight out further from the Hub.
Also dont let your warranty run out before you have them done!! And it is not safe to drive on a bad Hub. Hubs can catch fire.

Replacing them is pretty easy.

1. Remove tire
2. Remove 36MM Nut from axel
3. Flip up break caliper
4. Remove Brake Rotor
5. Unplug and unbolt ABS sensor from control arm.
6. Remove 3 bolts from back of knuckle-It might be 4 bolts Its been a couple years and I do not remember. The hub assembly will fall out.
7. Do steps in reverse order.

Note: You will need 1/2 drives/sockets and and a long breaker bar for this job. And a pipe to slide over the breaker bar. Those bolts are tight as hell. also I torqu'd everything back to 150ft. lbs. Also a couple cold ones will be need aftward as well. The job is relatively easy but requires energy.

Cold ones are a requirement for any job well done!

go to cerritos hummer right up the freeway, ive had nothing but great dealings with their service dept and they really appreciate the business.

Biggest problem is with an aftermarket warranty they may send an adjuster out to inspect the truck. His job is to find any reason to deny a claim. Tried to help a guy out with his transmission once and the adjuster came out for an inspection and would not leave until looking under the hood, yup he found the supercharger. Denied. Not the dealer that denied the warranty.

I don't buy that..... I think you're right in theory but in reality, a 37 inch tire is 4 inches taller than stock. 2 inches of that is above the axle.

Having said that.... I can't believe that the geometry is affected that much with a 2 inch taller tire.

Like I said, I agree with theory but not in reality. Kinda like saying a waxed truck gets better gas mileage. Yeah, in theory but.....

Got mine at Advance auto parts for about $190 each including tax. Go to gmtruckclub.com and search---there's a great post with pics and step by step instructions. Its pretty basic stuff---hell I could even do it. But, eat your wheaties. Those 22mm bolts holding the calipers and the 15s on the hub are TIGHT. The earlier post is spot -on, you definitely need a breaker bar. I had a clearance problem with the 1/2" drive on the hub bolts and had to use the 3/8" drive. By the time I was done I had busted 2 15mm sockets and 1 ratchet. Good old Sears took 'em back----didn't tell 'em I was using a 3 foot pipe on the ratchet.

Hub bolt is a 35.5 mm but a 1 3/8" will fit great. I used a 3/4" drive socket and big ass breaker bar.

Good luck--
