My 2007 1550 is making a rattle and creaking noise in theright front-end. Noise happens on intial acceleration and at the end of slow down. The slightest bump or deviation in the road will produce noise. Any ideas?

 

Suggest you check front suspension brackets that are mounted to the frame. I have had this noise and found that the brackets were breaking out of the frame. GM has declined to warranty this problem that many people in my area are having.
