Mama's bone stock 03 Denali popped the "Service Brake System" and "Service Stability" notifications tonight along with the brake light and ABS lights coming on.

They don't come back on immediately on restart,but every time we drove it again they did come back on.

The only thing aftermarket on her rig is 20" Centerlines with 275/55R20s.

Any ideas on where to start?

Thanks,Sean

 

Check your front hubs and see if you have a wheel bearing going out.

 

Cool.

Can you tell by jacking up the wheel and rotating/pulling back and forth on the wheel?

 

Yes, I jacked mine up and grabbed the top and bottom of the wheel, rocked it back and forth and it was sloppy as hell. I was surprised. Compare the two front wheels while you're at it.

 

Will do.

Did you have the same warnings as we're having?

Also,how much $ are the parts and how much time to swap out?

Thanks,Sean

 

Pretty much same warnings, with a C0245 code also. Hub assemble was 130 from the local parts store. Took a couple of hours to do, but I was taking pictures and drinking beer at the same time.

 

Right on,is there a good writeup somewhere for the hub swap?

Also,is that your truck on the deck of an aircraft carrier?

 

Ha! yes my truck but the ship is a cargo ship, or roll on/ roll off ship.

 

Sweet. I thought the pad eyes looked a little weird. I put in about 10 months on aircraft carriers(Lincoln,Kitty Hawk,mostly Contellation)when I was in the Marines.F18 airframes.

Anyway,I jacked up the front end and the wheels don't feel like they have any slop in the bearings.

The front end seems a little bit growly,can they be going bad and not be sloppy yet?

 

It is possible, but I can't be sure.
