Skank, I read both definitions on wiki, and to me ther is not a .05 worth of difference. As torque wrenches are not always used per-pendicular to the earth, so if your pushing up on a torque wrench its ft. lbs of energy that clicks the torque wrench, if you push down on it, its more of a gravitational aspect. So to answer your question, is the truck or car pushing down on the rear differential, or is the rear differential trying to push the front of the truck up? Personally I use ft. lbs., as that is the way it is stated in most manuals.

As i learned in my Ag mechanics class last week

lb-ft is a measure of tq
ft-lb is a measure of work

the only diference is the rotation force = torque instead of a linear force

I would argue that one with him, torsion is torsion period, weather the rear axle being put into a torsional force applied by the driveline, or you pulling on a torque wrench putting said fastner under torsional force to tighten it. I have also never pulled a torque wrench in a linear motion, always an arc motion. Now if we were talking about streching a stud with a hollow hydraulic cylinder (a linear motion) and then hand tightening the fastener, then releasing said fastener, I would agree, but then we are talking about an entire different unit of measurement which would be pre strech represented in psi or kPA or Bar. Which is typically what you are trying to achieve when torquing a fastener.

And in reference to the OP

engine makers have always held back, hell look at the 12v cummins with the p7100 injection pump AFC, break off the tamper-proof bolt and give me a screw driver and i can have you smoking tires in 10 minutes..

As for 800 ft-lb (lb-ft whatever) of torque..well i should hope with all the electronic BS on motors these days they better be able to hit that factory cause my 12v on the stock turbo has dynoed at 883.....

Vince as well as a few other Ford techs will give you an exact proceedure for checking a LS rear end, it uses none other than ta-da.....

















































A torque wrench, which is the identicle unit of measurement period.

Yeah, but can you still get 17-18 mpg?

In all seriousness, a unit of measurement is still just that. 1# at 1 ft. is 1 ft. lb. up, down, side to side. It is still 1 lb. at a measured length of 1 ft. lr any devisible there of. I.E. 2 lbs. at 6 inches. a 1/2 lb at 2 ft. no matter if its work performed or whatever you want to call it, its still the same.
