If the Crow Foot Wrench extend beyond the length of the Torque Wrench you need to calculate the Troque.
If the Crow Foot Wrench is to the side of the Wrench at a 90 dgree angle and stays at that angle (see the thumb nail pic) you do not need to calculate the Torque.

If you are going to use the Crow Foot in a manner that extends the length of the wrench.

cool, I knew there would be an angle to work. are you sure it's 90? I was thinking something like 120...

anyway, on a crowsfoot socket, the increase is negligible so 90 is likely perfect.

I looked up that info about the time I did the U-joint replacement.

I did not record in my notes where I got the info on if the wrench is 90 degrees to the Torque Wrench it does not change the Torque. But, I read it someplace and was surprised to see that was the case.

Phil, if you intend to replace the center bearing only just slide the rear shaft with bearing support out of the spline. (after careful marking).
Remove the two rear most exhaust donuts, leave the rest alone. Probably rusted tight, why make a big job out of this. Four little bolts to drop the diff, five minutes.

I may be doing that since I don't have a covered area to work and it's on a gravel driveway and the rains have started. I may do this the quickest way I can and then go back next spring when it's nicer out to replace the flex discs etc.

Had my car at the shop today to change center bearing. Just removing the 2 donuts on the center mufflers gave enough room to remove the driveshaft shield. Nothing else went well ( another thread about that ).
