I have a 2003 Buick Redezvou CXL AWD. Every time I make a right hand turn I hear a creaking noise from the front end ( dealer has replaced various front end items the sound goes away for approx 500 miles then comes back this has been done 5 times and a factory rep got involved & he said it was a normal noise ). I also get a AC fan ticking noise in the summer months each time I step on the break they can't fix this noise also. Any help any Ideas car has less than 36K.

Optional Information:
2003 Buick Redezvous 3.4l

Already Tried:
Dealer repairs which have not worked.
