The importance of having strong nuts :D - Toyota Yaris Forums

eTiMaGo · 04-10-2009, 03:31 AM

could not resist the title

But, yes, a bit of a warning about cheap lightweight aluminium lug nuts... Don't overtighten them:

On the left, a normally tightened one, on the right, one which was tightened with herculean might... On the side where I had the accident, so I don't know WTF the body shop used to tighten them. Went for a wheel balancing and rotation yesterday and we noticed this... Lucky my wheels did not fall off!

Happens all the time to steel ones, too, when those pneumatic impact wrenches are misused. I was once head-oned by the P215-75R15 wheel and tire from the left front of a big Oldsmobile Cutlass. It bent the front bumper of my 1983 Dodge Ramcharger into a V and broke the grille behind it, also damaging the air conditioning condenser. As the thing had been bouncing head high, I was thankful it hit me at bumper level! We were going about 40 MPH in opposite directions, it would've been worse at highway speed. Stripped lug nuts. My wife also once had the left rear wheel of her Mustang come off and pass her. Same thing. I've encountered stripped nuts several times when I went to remove a wheel with a lug wrench and found the nuts would turn but not back off.

Isn't it even more common if you use the aluminum lugs? I've been told if you don't use anti-seize on aluminum lugs with steel threads that they can seize together easily and strip.

I think I'll stick with steel lugs for now.

Frankly, I think aluminum lug nuts are an appallingly stupid idea. But with either type, you have to use some common sense and follow proper installation procedure.

Yeah its called impact gun level number 5. This is why i hand torque all my lugnuts to 76 ft lbs manufacture specifications. Only gun them on on number 1 and hand torque them the rest of the way. Funny thing is even at number 1 sometimes the torque wrench clicks. So id be afraid to ever use number 5.

those brutes!

tire shop guys did the same thing to mine once, which is why I split my spline drive adaptor trying to get them off later. hand torquing, its the only way to go
