Wheel loosens on 2008 Toyota Tacoma
Three years ago, the right rear wheel of my 2wd Tacoma literally fell off while I was driving on a city street. Mechanic who fixed it blamed the aluminum rim I had been using, said it flexes and loosens the bolts. Since then, I have replaced the aluminum with steel. Last week, the same wheel nearly fell off, this time it was the stock steel rim. The truck is used lightly - has less than 30K miles. Lug nuts and studs have all been replaced since the original incident. Wheels were mounted by a mechanic or by me, tightening lug nuts as much as possible with crappy Toyota lug wrench. So - why is this happening? What can be done to prevent it (short of Loctite)?
