Quick questions about the axle nuts

[WildHorse]

12 bucks for some cheap insurance & marked. Replacements are notably heavier.

WOW! That is impressively clean. Just had my wheels off over the weekend and noticed how rusty the whole area was. Cleaned it up a little bit but no way near as clean as yours looks.

I like to keep things clean-ish. Anti Seize helps haha.

The picture on post #17 shows the factory put some kind of markings on the nut and axle, so if that's present on my car, and they line up, no need to even check things, right? Since I don't think the factory would mark the nut and axle without tightening them, right? Even with Ford's lousy QC standards, I doubt it'd happen. Or am I being too optimistic? Ha ha.

I marked it. Those are the new retainer nuts.

Oh man. Well, never mind. Factory marks almost everything, so surprised they don't mark more critical fasteners like those. Oh well. I'll put about 150 ft/lbs of torque on them if not marked, and if torque wrench clicks, then mark them myself, for future reference. Thanks.

I’m abt to do this bs too. I guess I’ll torque them to 150 because Wth is adding 45 degrees why not just give us a total in ft lb of torque. My torque wrench goes to 250

 

[Unas2k5]

It's 90 lbs-ft plus a additional 45 degree which would bring it to over 200 lbs-ft. Marking the nut is always a good idea.

200lbs ft? Why didn’t they just say that instead of 90 plus 45

Cause the want it in steps I guess. My lug nuts I do two steps of 75 ft-lbs.

According to the interwebs...

...the torque spec is the ideal value for a bolt's preload force. The problem is that it's difficult to accurately read fastener torques because of differences resulting from lubrication, under-head friction, and tool repeatability. Using an angle, however, you can predict reasonably well the preload the fastener will provide and measure the angular difference very accurately.

Do the 98 ft-lb with a torque wrench. Then add another 45 degrees with a breaker bar. That’s the best play.

What symptoms does a loose nut cause?

 

[Bossdog]

So I a assuming the only way to remove and retorque the axel nuts is to have the Manual transmission in gear?
When loosening, Forward gear (1st) and when tightening reverse? or it doesnt really matter if the gear selection opposes the turning force?Just want to make sure I don't "F" anything up when using that much force.

I think I may go to Harbor freight a purchasing a GBFBB. I initially thought the one I purchased for the 150 ft/lb lug nuts would be enough but I'm now rethinking that.

I usually have the parking brake on and the car in gear to torque that thing. I indiscriminately use 1st or reverse. Sometimes I even have the car on the ground. (I don’t use center caps because they melt)

Because 90 plus 45 gives a precise amount of bolt stretch which is what keeps the joint tight. The 90 takes out any play then the 45 degrees adds about 0.2 mm (0.1875 to be exact).
