Because, by the time you twist that bolt to let's say, 65ft.lbs, it could snap.
The manufacturer of that bolt knows that if the bolt is torqued, (Stretched) to a certain torque value, and is turned a certain amount of degrees, the proper torque value will be reached, and still stay within the guidelines of the tensile strength of the bolt.
Torque is set to Bolt Stretch. How far the bolt will stretch in a given torque value, and not exceed it's tensile strength. The threads are stretched over to one side a little also, and this causes the bolt to be locked into position. They can only be 'tweaked' over to one side so many times, then they will fail.
Also the bolts have a certain tensile strength, and can only be stretched so far, and So may times.
MANY, manufacturers plainly state to not reuse a head bolt of this nature. Reasoning, is that the bolt has been stretched, and stretching it again may cause failure of the bolt.
Plus, every time the engine reaches the operating temperature, it stretches the bolts, then the bolts contract once the engine has cooled off.

You are talking about a hub on a spindle of a front wheel drive car? You took off the nut to get to the bearings? Pulled the pin and the nut just spun loose? Am I right so far?? If so, then yes, this is normal, no bearing gets tightened any tighter than finger tight or it will burn up. I don't know where the torque specs came form, unless they are talking about the caliper to hub bolts if there are any,it might be metric, 199 kilograms per centimeter or whatever they go by. But still wouldn't be for the bearings. Put the torque wrench away, I have never used one in my life, except for head bolts. Hope this helps.

Step 1- 22 FT.LBS.
Step 2- 48 FT.LBS.
Hope this helps you.
