I remember reading some time back, about incorrect wheel lug torque creating warped rotors. Who knows the correct torque for stock alloy rims? Firestone had them torqued to 150ftlb. that can't be good. I backed them off to 80ftlb., but would like the factory figures.
Thanks

 

Your Owner's Manual should say in the "Changing a Flat Tire" section. However, it is probably in the neighborhood of 80 to 85 ft-lbs, as the the spec. for the GX is 83 ft-lbs.

Whoever tightened them to 150ft-lbs should be fired; I don't know of a single passenger car/light truck that requires that much. I think the Mercedes M-class is the highest at 110 or something in that neighborhood.

 

I remember it's 76 ft/lbs for my RX300 stock wheels, but I can't find it in the manual.

Yes, uneven or over torque can warp rotors and damage threads.

 

I agree on 76 Ft Lbs for wheel lug torque for both factory alloy and chrome wheels. I also lubricate the threads with a little dab of grease, say LubiPlate Lithium white. But, personally, mine are at 75 Ft Lb as it is a easier number to remember...

 

Thanks for the replys. I'll have to take a good look at the rims to make sure they didn't crack. It took every bit of my strength and a 2 foot long torque wrench to break the lugs loose. I'm 190lbs. Anything I should look for besides cracks?

 

Service manual states 76ft-lbs

Stay away from grease, unless it is for high temp. The right product is anit-cease compound.

I torque the keyed-lug the last and un-thread it first.

Stay away from shops that use impact wrenches. A good shop uses torque wrench to hand tighten lug nuts.

 

Possibly lateral runout of the rotors that may have been warped by excessive torque - especially if tightened out of sequence - check (or have your brake shop check) with a dial indicator. . . or check for shimmy of the steering wheel when braking moderately from 60+.

 

I agree, but this is tough when even the Lexus dealerships don't torque it properly and use an impact wrench on your car. Not every employee does this, but any do. I make it a habbit to retorque my wheels everytime I know someone took the wheels off. I've gotten my car back from a dealer service and found the lugs over torqued on many occations.

 

The manual for my last car warned against using any lubricant in the wheel thread. I suppose you could use some spark plug grease to prevent seizing. As long as you rotate the tires at least once a year, you shouldn't have to worry about it.

If you were a NASCAR fan, you'd see the Unocal #76 orange ball all over the place.
