Lug nuts won't stay tight

[SunsetBengal]

While it is imperative to jack the vehicle to properly tighten the lug nuts, you may have to check and see if they are to be torqued to a specific number. But, generally speaking, you should be able to tell by visual inspection if there is any damage to the lug studs.

Edit: You'll only get the lug nuts so tight, with the wheel elevated, if doing them by hand. Final hand tightening is done with wheel back on ground.
