Wheel Nut Torque Setting?

[Guest Close Guest]

How important is it to match nuts with holes in wheel rims?

It is very important to match the nut with the hole. If you put a tapered nut into a counterbored hole, the nut will start to chew out the corners and may eventually come loose. The same will also happen the other way around. The tension of the nut and stud, together with the friction between the mating surfaces is what keeps the nut from coming loose.

thanks! I better buy a few spare washer nuts and brief the tyre service thoroughly when they change wheels around.

OK - hadn't thought about this. Don't have a torque wrench but did a tyre rotation for the first time myself last month. Just tightened up to what to me appeared reasonable. Will never do it again - at my age I have trouble moving the buggers from wheel to wheel.

Thread revival

Rotated the tyres today for the first time, the old fashioned way no rattle gun used. The owner's manual says wheel nuts to be torqued to 83 ft.lbf, so I tightened as prescribed. This seems low to me, thoughts...

Spot on!

I do them with the rattle gun, but to 110nm no probs

I have since upgraded to a Makita LXT 1/2 inch cordless impact wrench and Kincrome torque bar/socket. Works great at home and in the bush.

Very nice. The torque bars are a very good way to go.


Once you put a bar like a torque wrench on a wheel nut, if you don't hear the click or it is set wrong by mistake well bye bye stud.
Rattle gun, unless its on Viagra you will be there all day trying to break a stud.
I have seen many trying to do the right thing break studs.

And this happened to my left front wheel studs last night.
I have always used a 1/2" drive torque wrench set to 83 ft/lbs. When remounting the road wheels back onto the vehicle.
I had not had any dramas until I had the BFG KM2's peeled of my rims and the Duelers put back on for daily town driving.
As the tyre shop thug mounted the last wheel back on the Prado, I noticed him rubbing a stick of dry lube on the studs...WTF..
"Did you coat the rest" I asked. "Yeah mate these were dry as ay" thinking he'd done me a great favour...
He then proceeded to tension the lug nuts..
So on arriving home I lifted her up and removed the over torqued nuts and cleaned of the threads of studs and nuts with brake cleaner and brush, then dried them with compressed air.
On remounting wheels with 83 ft/lbs set on the torque wrench I could feel that some of the nuts were going to go beyond the preset torque.
Now yesterday I changed the front diff oil.
To get better access to the filler plug with my oil suction gun I removed the left front wheel.
Remounted the wheel lowered the jack to cantact the wheel to the floor, then proceeed to nip up the wheel lug nuts.
Taking things easy and working in sequence, then crack the first stud snapped - "Gosh" I uttered.
Continued with caution then, crack "Golly Gosh" this time!
So with only 4/6 of the left side front nuts on the wheel, it was a steady trip to work this morning.
Toyota Dealer has 4 on the shelf and getting in another 2.
Might back off the ft/lbs on the torque wrench a couple of clicks.
From this expirience I would recommend not lubing your wheel studs.
Kept clean they should not become a problem.
Cheers Troy

If the threads are lubed, they should be torqued at a different number:
