I just installed the rotors on the front spindles and wondered about the proper torque. I know the Chilton's manual says to torque the nuts to 25 pounds while turning the rotor then back off 1/2 turn and then torque to "10-28 inch-lbs". I torqued the nut to about 3 ft-lbs since my torque wrench doesn't read in inch-lbs. The rotor turns very nicely and has no slop or significant resistance. Does this sound like I did OK? Thanks for your input.

I do it by feel, so its hard to describe here.

One thing I wanted to point out, is that I recommend the Timken A5/A12 bearings as they are all STEEL cage (not factory NYLON). Its about $40 for both sides, and since you're in there already...

Cameron,

That sounds exactly how I did it. No problems yet. Don't forget the cotter pin!

The Ford service manual says the "10-28 inch-lbs" is finger tight.

Are you not willing to pay $150 for a dial in-lb torque wrench?
Want a quick and dirty way to determine those subtle measurements?
Well, behold, LuisO's patented and SAE approved in-lb dial torque wrench:

I needed to measure this for my IRS rebuild (pinion bearing preload) and put this artifact together. The wrench measures 4.5" , the fish scale, while not exact, I don't think will have more than a 2 lb. error (don't believe me, it says it right there, "Deluxe")

So if you need 10-28 in-lb of torque, let's see:

10 / 4.5 = 2.22
28 / 4.5 = 6.22

So when you pull on the wrench using the scale handle, when it measures aprox 2 1/4 lb, you are exerting 10 in-lb of torque. The same when you read 6 1/4 lb, 28 in-lb torque.

So, aim for the middle ground between 2 1/4 and 6 1/4 which is 4 1/4, so even with this not very exact measurement, you'd be within spec.

Yeah, go ahead and call me crazy.

Hey, thanks for all your input. LuisO, that is an amazing setup you have there! Impressive! This forum is amazing and I am sure many future questions will be answered as I forge ahead with the project. Thanks in advance!

Multiply foot-pounds by 12 to get inch-pounds.
Divide inch-pounds by 12 to get foot-pounds.

Luis,

While I greatly admire your engineering feat all you had to do was ask to borrow my inch/lb torque wrench
