Yesterday I was on my way to a job. Driving on a narrow twisty 2 lane. Over the stereo I could hear a steady clunking noise, and felt a vibration.<p>Thinking to myself damn a damn front u-joint was about to fly apart I pulled over. Got out and started looking everything over, both joints on the front shaft were fine. Next checked the joints on the outer axle stubs, those were fine too.<p>Got back in drove about 20 feet at 5 mph with stereo off. Could really hear the clunk clunk. Now I'm getting peeved, thinking a front hub? Then it hit me. Lugnuts!!<p>Sure enough all eight lugs were loose on front driver side wheel. A couple of months ago I put some aftermarket aluminum wheels on my truck. After the first 100 miles I retorqued the lugnuts and than promptly forgot about them.<p>While stopped I checked all lug nuts on all 4 wheels, and there were others beside the driver's front that were loose.<p>Could have been expensive if I lost a wheel not to mention dangerous as all hell.<p>Just thought I'd share my experience. A little preventive maintenance goes a long way . Even if it's something as simple as checking your lugnuts.
