Not to be picky, but torque is measured in lb/ft. Work is in ft/lbs.

I know, Everybody says it. Just the engineer in me trying to get back out.

Ft/lb is to measure energy. Lb/ft is to measure Torque.

Jesus H. Who let the engineers in?

Set your torque wrench to 96 whatever-the-eff's and you're good to go.

My torque wrench does not have ft/lbs on it, it has newton-meters. So I need to set my torque wrench to 130 nm to get 96 ft/lbs, correct?

So then I would want to set my torque wrench to 135.5 nm?

Theres a revised spec for the wheel bolts, something above 100 ft-lbs. I dont know if that spec was retroactive to all models.

Also, the threads are lubricated but the sherical cap is not.

All interesting but when was the last time you calibrated your torque wrench?

About a year ago. Why do you ask?



Having said that, I now use a torque stick on my MG725. I checked it with the torque wrench the first few times but it was always so close I stopped checking.

I used to have mine checked yearly because I used them so much. I'm surprised how off they can get. I actually wore a torque wrench to the point it was no longer able to be calibrated.

For wheels I just told the techs to buy a cheap harbor freights and compared the torque value with a known good one every once in a while. No need to wear out a expensive torque wrench on lug nuts.

Smile Fitting wheels

Hello I live in the UK. I have never in my life used a torque wrench on the wheels of any of my cars. I am now just on 66. The car I have now is a Boxster S 2002. The first thing I do when I buy a new car is take all the wheels off so I can copper grease the threads, then use a spider to tighten. This has been my procedure for all those years.

This is the accuracy you need with each lug nut:

I check my click wrenches against my beam wrench all the time.

When I started using a torque wrench for this, I was ashamed how far I was over torquing. Made the car feel or ride different I swear.
