Three times today my excursion has made a sound like I am running over rumble strips - except I am not. It happened at different times at different speeds with different engine RPM's. It goes away with application of the brakes.

I crawled underneath and can't find anything obvious there.

Any ideas?

 

This might sound too simple but it happenned to me this spring.

I changed the winters on steel rims to summer rubber on the stock aluminum rims. I hadn't tightened the lug nuts enough and a few days later I heard the "rumble strip" sound on light cornering. And it was not affected by braking.

It was the lug bolts clunking around and chewing apart the holes in the rim.

I told ya it was simple...and kinda stupid as well.

 

Check your carrier. They can start to give the feeling of vibration as they wear away. Just a thought.
