Reply to "Wheel bearing replacement"

If you want to use a extension on your torque wrench. There are formulas to ensure you apply the correct torque to the wheel bearing. I can do that at work tomorrow if you wish.
Rules to torqueing a fastner:
1) Any extension added to a torque wrench will alter the torque being applied. i.e.- A extension making the wrench longer will alter the true torque applied to the object, lets say your using a crows foot...straight away from the head will alter the amount to whatever is being torqued, at a 90 degree angle to the head of the torque wrench will not affect the torque being applied.
2) Use of a extension to raise the height of the wrench does little to the amount of torque being applied. Alot of people will tell you not to do this because the "TWIST" of the extension will throw off the torque being applied. What little torque is lost during this "TWIST" is very hard to calculate and is considered mute.
3) When you tighten a fastner you should have a smooth steady pull on the wrench, no bouncing of the torque wrench..this will cause false readings due to shock loading of the wrench. Also you should apply a roughly equal counter torque to the head of the torque wrench to aid in stabilizing the tool. This will also prevent the socket, crows foot, etc from slipping off of the fastner.

This concludes our Torque Wrench 101. LOL
