When I travel over a bump or uneven surface, an annoying, rather loud rattle, like bang bang bang occurs. Seems to be LH front, down low from where the noise is coming from. I have been all over the car 3 times and tightened every nut & bolt I could find, but it is still there. Any ideas? Has a relatively new front end. Could it be brake callipers?[&:]Thanks

 

does it sound like a loose rattle or like somethings broken could be battery box or bumperbracket or something

 

Thanks for the advice - its more like a thud thud thud each time you hit a series of bumps

 

Check the motor mount on that side.

 

Thanks - will do and let you know

 

Turns out to be LH brake caliper - piston on the way out - have had a pair reconditioned and ready to install. Thanks for the help
