Need the torqe specs for the three bolts that mount the hub and bearing assembly for a 2002 4wd trailblazer

Three bolts are 70 lbs,could be 120+/-.

The front wheel bearing is a hub and bearing assembly. To remove you will.... 1. Remove the tire 2. Remove the axle nut. You can put a punch in the fins of the rotor to keep the assembly from turning while you rmove the nut. You can can do the same thing when you torque the axle nut. 3. Remove the caliper and rotor. 4. Unplug the abs sensor if equipped. 5. Remove the three bolts that hold the hub to the knuckle. 6. Rmove the hub. If you need torque specs let me know and i'll get them for you. It is absolutely critical that you torque the axle nut to the proper spec!
