2006 GMC Yukon - back tires locked

I just had my drum brake replaced but now my tire light came on is that the reason why my back tires locked on me

No. Take the truck back to the shop that replaced the drums

Nevermind i got my rear end replaced

Did your differential lock up?

Your truck has disc brakes all around

Did you have a used rear end . . . from another truck, I presume . . . installed?

And did you swap over any parts, or use everything from the donor truck, including the brakes?

no . . . the tpms light has nothing to do with the brakes locking up

The tpms light is probably on because of incorrect tire pressure(s) or a dead battery in one or more of the sensors
