I recently put some ASA rims with Blizzak tires on my 2004 LS430. Several days after putting them on I heard strange sounds from the front driver side wheel. Went to my local Lexus dealer and they found only two lug nuts on the front driver side wheel. The other 3 lug nuts were gone and one of the lug nut studs was broken off. How could this have happened? I put the rims on myself and tightened them with a torque wrench.

Also how hard is it to replace the lug nut studs? Is this something I can do myself? Thanks!

 

very strange. Just wondering if the dealer did a service requiring them to remove the wheels.

If you torqued the wheels on properly, the 3 missing lug nuts and the broken stud must have been done at the dealership ... these are not things that fall off and break easily at all. Must be a sloppy Lexus dealership to return your car to you in an unsafe condition. I would speak to the manager.

Unless you have special tools, I don't think you'll be able to repair the lug stud yourself. Pretty sure it needs to be drilled and extracted - something I would not personally try to do.

 

prob overtightened and snapped off.

replacing the studs are easy, youtube some videos and there are plenty of DIYs.

 

maybe some hater wanted to get your wheels ??
similar happened to my boss´s car, where someone wanted to steal wheels or just do some harm, so the nuts were loosen and the wheel flew away...noone hurt !

 

Did you use the correct lug nuts for those rims? I believe there are a few different seat/mating surface designs for the nuts: round, flat and conical. If you used the wrong ones then even if you torqued them I can see them loosening fairly easily. I am not sure what the stock lug nuts are but I know the lugs for my aftermarket wheels are different than the stock ones.

 

the nuts become little lose, over 500 mile period- you are suppose to revisit and double check if everything is secure. My wifes friend RX350 had her wheel almost come off after 4 months of a brake job.
