* Wheel Lug Nuts: This is the most common thing people think of. The torque spec for these is typically in the range of 100-110 ft-lbs (135-150 Nm). Always check your owner's manual for the *exact* specification recommended by Chevrolet for your specific vehicle.
* Axle Nut (if applicable): If you're working on the hub assembly itself and removing the axle nut, this will have a significantly higher torque specification. You'll need a workshop manual or a service manual specific to your 2006 Silverado to find this value. This torque is *critical*, getting it wrong can damage the axle.
* Other Bolts: The hub assembly may have other bolts securing various components. Again, consult a repair manual for those specific torque values.
Crucially: You absolutely must consult a repair manual specific to your 2006 Chevrolet Silverado's year, engine, and trim level to find the correct torque specifications for each bolt. Using the wrong torque can lead to stripped threads, loose components, and even serious safety hazards. Incorrect torque can also damage the wheel bearings.
You can find these manuals online (some are free, others are paid) or at an auto parts store. Your owner's manual may also contain some basic torque specifications, but likely won't include the more detailed information you'll need for hub work.
