Lug nut
Do anybody know what proper torque for lug nut on lr3 is
I replace brake yesterday and I have treble to take wheels of.
I broke lug wrench trying to get lug nut loose. How tight lug nut need to be

I use 100 lb-ft but I'm not sure if that is the spec.

 

[USAFbuckeye]

The spec is ~140 Newton meters.

Really? I was pretty sure Discount Tire only torqued them to 100 lb-ft.

No, you're right. I'll edit that to read ~140 Nm (newton meters), not ft lbs...

I never trust the tire shops, so I always loosen and then retorque my lugs to spec after anyone touches the wheels. I keep a pipe length or collapsible breaker bar in each car for leverage on over-tight lugs. Worse situation would be stuck out on the road with a simple flat but unable to loosen a lug because some knuckle head over torqued it.

Is it safe to change out one (1) lug nut while the D3 is sitting on the pavement - not jacked up? Would this cause too much stress on the remaining lug nuts / wheel?

Not sure of the official answer, but I would not hesitate to swap out lugs one at a time without jacking. Ive driven around for weeks with one missing (state inspection mistake).

I would not do it. It takes 2 mins to get the weight off with a jack.
