Torque and Chrome

I have a 160 ft lb torque wrench and I need to torque to 177ft lbs?

This is a hub bearing nut on a 2003 4wd Yukon. What should I do to ensure I get the proper torque? I could tighten, torque to 160 and give it a slight tap on the end of a breaker bar with a rubber mallet or something like that? Been told not to overtorque. Any suggestions? Aussie, I was not going to bang on my torque wrench. If I were to do that it would be with a 3/4 rachet or breaker bar.

1. Rent the right wrench. Don't take a chance.
2. do not overtorque it as you can damage the bearing, axle and or driveshaft what to do is tighten it to 160 then head straight to your nearest tyre depot/mechanic as they will have the neccessery equipment to tackle this job 160 is tight enough to get you to somewhere whick has the right torque gear (a Snap-On Techwrench is best for this as it is the most accurate in the world)
3. The proper tool for the job is recommended. You wouldn't do body work with a household hammer, would you? You need another torque wrench and you need one that will go to at least 250 lbs of FT. The best thing to do is go to a specialty store and buy an inexpensive one or, depending upon where you got the one you have now, upgrade. Some places will help you do that. They might know of someone looking for the one you have. Some of the stores that deal in all sorts of close out items would be a good source as well. Good Luck, Rick
4. Rent the correct tool. Giving your torque wrench a tap can (and usually will) ruin it - it will no longer be accurate. And using a breaker bar still won't give you an accurate torqueing. This is not something you want to get wrong.
5. Unless you are the Incredible Hulk, you can't overtorque the nut by hand. Give it the full 160 and crank it just a little more.The bearing manufacturer is more concerned with using an impact gun to tighten the nut
6. many parts stores will lend or rent ou a bigger tourqe wretch
