I used to use a Wrench and a 3 pound hammer to make them tight. You can tell when the wrench is tight and not wanting to turn more and get them all pretty close to the same tork. Now I use a 350 ft pound electric impact works great. Mark H.

450 lbs ft means 450 lbs using a 1 ft lever. This is the same as 225 lbs using a 2 ft lever or 112 lbs using a 4 ft lever or 56 lbs using a 8 ft lever. So, using a "cheater" on your 3/4 socket/drive you can do it with quite the accuracy.

Dueing WWII, my dad showed the supervisor at MARTIN ACFT CO., Baltimore, MD, how to make a driver (torque) for screws that were used in the assembly of MARTIN BOMBERS.

When a special designed wooden handle starts to "slip" on a screw driveR, well, THAT WAS TIGHT ENOUGH.

He was almost arrested at the GUARD SHACK when he happened to have one of the GOVERNMENT's ideas in his hip pocket!!!!! !!!!

Reno,

I use a 1/2 inch breaker bar and tighten it as tight as I can and haven't had one work loose yet so it must be snug enough.

Hi RENO,

Last summer I had my van inspected at an inspection (PA) certified service place. Next to my van was sitting a 1990 FORD escort. From time to time the Escorts need the "CV" axel replaced because of torn or broken rubber boots.

Well the mechanic changing the CV axel used his pneumatic driver, the type generally used to tighten the lug nuts on wheels.

The mfg. serv manual requires 450# torque on the axel nut to properly seat the CV axel.

The mechanic finished the CV axel installation. He proceeded to tighten the lug nuts on the wheel. Of course the lug nuts were a different size than the axel nut.

He changed sockets and spun the lug nuts on. The torque on the lug nut, according to the FORD service manual, should be 60#torque. Needless to say, the owner of the ESCORT lost a lug stud. He charged HER for a new one.

I always re-torque my lug nuts after inspection.

Moral of the story, if you use a pneumatic torque driver, don't forget to reset the torque for the next NORMAL use. I guess, changing wheels.

Hope this helps.

The box the cv shafts come in says that if you use a gun that the warranty is void. They also make torque sticks for all makes of cars so when you use a gun on the lugs that you do not over torque the nuts and worp the brake rotors. You just got to go to the shop that cares enough to do it right. The 450 foot pounds is not any worse than torquing a pinion nut to crush the cursh collar in a differential. Go get a really long pipe. It works great. Use a good braker bar and socket, such as Snap On.

Try to find someone who has a 3/4 drive tourqe wrench. I tryed to guess on mine and went way to tight.The axle would turn,but it was way to tight.Hope I didn't stretch the splines.

Socket with 2' breaker bar and all of my 225+ pounds hanging on the end. There are other methods too.
