Front Hub Castle Nut

[CraigC]

Does anybody know offhand what size socket is needed for the front hub nuts?

Pretty sure it is 1 1/8", but I wouldn't bet my life on it. Hopefully someone else will confirm or reject my recollection.

Confirm - just measured one at 1-1/8"

Thanks guys. Figures that the largest socket I keep here at home is 1-1/16.

Might as well buy the deep version 1-1/8" socket; if you don't, you'll also need to use an extension (assuming wire-wheel hubs).

While using an extension isn't so bad in itself, it can deflect somewhat, not resulting in an accurate value when using a torque wrench (follow the manual, on selecting shims and final torque).

Randy--

I'll agree that an extension might matter when using an impact wrench as some spring in the extension might absorb some (dynamic) torque but my understanding is that with static torque such as we exert through a torque wrench whatever momentary spring action there is will "add back" when the "spring" in the extension unwinds. And with anything over a 1/8" drive set I just cannot imagine that there is any measurable spring action.

Does this make sense to you?

Yes, a straight extension will not affect the correct use of a torque wrench. The torque is simply transferred through the extension. But because the extension is in equilibrium, it must have the same torque applied at both ends. Torque measured by torque wrench = torque applied to socket.

Speaking of extensions and torque, I noticed my tire shop tightens the wheel lug nuts using a air wrench with various 'extension' like devices. I asked the installer about it and he said the extensions limited the amount of torque applied to the lugs so they weren't over tightened. He said he had several different extensions depending on the amount of torque required. I looked at the tools and could not see any mechanical reason why they would have different ratings. The mechanic had no explanation other than he was told to use them when installing wheels.
Any one out there ever seen them and have an explanation of how they work?

A little searching gives: " An impact wrench works by hammering the shaft as it spins. A torque stick is basically a piece of spring steel. When it reaches the desired torque instead of tightening the bolt anymore it just rebounds against the wrench.

They are fairly accurate, although nothing beats a properly calibrated torque wrench. "
