Re: Lug nut torque & warped rotors
I hate to be Devil's Advocate here, but 80-125 quoted by the original poster
is not too far from 85-115. Perhaps the rotors warped due to some other
cause, and he is seeing the result in disparity of the effort required to
loosen the lug nuts. In the ideal world you would want to use a star
pattern and a torque wrench. In the real world you want to get the wheels
on and the vehicle out of the shop as soon as possible. It is impossible to
say what they do in that shop, unless you work there, or are a lawyer who
has received a lot of complaints about them.

Re: Lug nut torque & warped rotors
I hate to be Devil's Advocate here, but 80-125 quoted by the original poster
is not too far from 85-115. Perhaps the rotors warped due to some other
cause, and he is seeing the result in disparity of the effort required to
loosen the lug nuts. In the ideal world you would want to use a star
pattern and a torque wrench. In the real world you want to get the wheels
on and the vehicle out of the shop as soon as possible. It is impossible to
say what they do in that shop, unless you work there, or are a lawyer who
has received a lot of complaints about them.

Re: Lug nut torque & warped rotors
But the torque for each lug nut should be the same, whether it's 85 or 115.
It's such a known issue that uneven lug torque causes warped rotors that
most likely it was caused by the last person to work on them.

It's such a known issue that uneven lug torque causes warped rotors that
most likely it was caused by the last person to work on them.

Re: Lug nut torque & warped rotors
That range means 'all' of them should be at 85 ft lb 'or' at 115 ft lb.
They must be the same, not one at 85 and the next at 115, then the next
at 85, etc...
having some at 80 and some at 125 means it was not even slightly
torqued. Even a crappy torque stick (that will warp rotors for sure)
should be better than that.
