i am not sure what is the problem but i have loud banging noise coming from front passenger side underneath of the car when i drive the car over 100k.

Better get it checked out. Could be a busted mount or something loose in that area.

Get it checked out ASAP. Some things you can check yourself (which you may want to consider before you move you car again):

The motor mount (like Flippy said). The upper motor mount is pretty easy to check, just rub your hand around and underneath it. You'll be looking for an oily substance.

Also check to make sure all of your lugs on still on and torqued down. Lugs are also easy to check.

It sounds like you're sure the sound is coming from the front, however, if you're at all unsure about the location of the sound, I would also check the rear sway bar; although loose endlinks/RSB usually manifests itself as a clunking noise not a banging, and it mostly happens when travelling over bumps/uneven surfaces. To check the RSB, just crawl under the back of your car. Try to turn the nuts on the endlinks by hand. Also grab the bar and try to move it (I mean really try to move it!).

Good luck. Let us know how it goes.

Ya i would say motor mount, hopefully it's nothing serious. can't be safe with it happening with you driving at 100.

I would have it checked asap by a mechanic for sure.
