What to know about tightening the wheel lug nuts:
Whenever a car’s wheel has been taken off, it should be replaced and the lug nuts properly tightened. By properly, we mean with a torque wrench that tightens the nuts to the manufacturer’s specification. Many workshops simply use air wrenches that often over tighten the lug nuts. This is possibly dangerous and destructive, because it can hurt the wheel, stud and lug nut, as well as warp the disc brake rotor.
Facts to Note:
Every car has a suggested torque figure for the lug nuts.
There is a sequence best followed for tightening the lug nuts.
Any kind of grease or anti-seize compound should not be applied to the threads
Even without a wheel removal, it’s advisable to check the lug nuts from time to time.
How to Fix:
The vehicle is raised and held on jack stands
The wheels are fixed and the lug nut fixed by hand then only tightened enough to hold the wheel snugly
The vehicle is lowered off of the jack stands till the wheels just touch the ground and torque the lug nuts to specifications in a star pattern
The vehicle completely lowered to the ground and completed till all wheels are done
Have your wheels checked at every routine maintenance service, and ask the mechanic to ensure the correct torque levels are being observed.
Common symptom indicating you need to tighten the wheel lug nuts:
