I notice my sport GE8 has this issue
can't really explain it but everytime when I drive over a speed bump
I can hear ONLY the passenger side crunching
sound came from undernearth the car
like a steel bracket or suspension whatever is lose or something
but drives fine, no other issues
I thought maybe the sport package side body trim is lose but I check it and its not....
I will go to the dealer next week
anyone gets this strange noise on your GE8?

 

Possibly a stabilizer link gone bad.

Post back w/ a follow-up. You might hear it on lesser bumps as well.

 

check the bracket for the stabilizer bar bushing
