: Missing a lug nut - Problem for short term driving?

:hmm:Don't know how I didn't notice previously, but I'm missing one of the rear driverside lug nuts and come to find out that the stud is stripped. Figured I'd swing by a dealer and get one to fix it this weekend, but curious if there would be any issue with continuing to drive it. I've been driving for a week through 2 tanks of gas and doesn't seem to be much of an issue, but thought I'd double check...

Driving with only 5 of the 6 lugs is not a problem. You might check the remaining 5 for tightness (torque spec = 100 foot pounds).

Darkman's right. I ran for two years with a stripped stud in front with no problems.

Even better since something just grenaded in the rear door and now the window won't go up. Going to focus on that now...

Faber,

Call your dealer's parts dept to make sure they've got the parts in stock for you ... could save you a bunch of time if they have to order you a stud and a lug nut that they didn't have in stock

100 foot pounds on lug nuts? isnt that quite high?

Thanks again for the assistance. Pulled the door apart at lunch and one of the pulleys had cracked. Unfortunately the wire seems to be wrapped up pretty tightly so I'll get the wife to help later on & attempt to untangle it so I can at least get the window to the fully up position and then hopefully get it all replaced.

I still believe thats high i wouldn't go over 90 ft lbs in fear i would strip a stud, but thanks for the info

Was able to rig up the regulator to keep the window in the up position until the replacement gets here - ran a screw through the side of the rail to keep it from going anywhere. Thanks again to all for the help. Now time to order a few parts...

I always torque my lug nuts to 100 ft lbs and no problems yet.

RTFM... and you'll find it says 100.

I wouldn't do anything less in fear the wheel would come loose.

You can't go around and just guess torque specs, and expect things to be okay.

And you guys wonder why your studs strip...

Cross threading a lug nut will strip the threads on the stud, but excess torque will not. Excess torque (above the yield point) will break, rather strip the stud. In any event, the 100 foot pound torque spec is relatively mild. Chevy pickup trucks, for example, have a torque spec of 125 foot pounds.

lol...mine appears to be cross threaded at the end of it. Likely someone was too aggressive with a air tool before seating it properly.

In 20 years, I don't think I have ever used a torque wrench on wheels. I tighten them until they are snug, then do another third or so turn.

Subaru probably uses Chineese titanium. RTFM....if it says 100 ft.lbs then torque to 100 ft.lbs. FYI....The 2009 CTS requires 140 ft.lbs.....
