Any suggestions regarding the alignment on my 03 cts. This will be the third time I will have to pay at the dealer for another alignment and this is getting rediculous with the amount each time costs me. Everytime I drive my car is rattling like you wouldn't believe. Anyone else experiencing this problem. I had new tires put on less than a year ago. Love this car but a little frustrating. Thanks

I have done hundreds if not thousands of alignments.
Never ever fixed a rattling problem by doing an alignment.

Maybe should have explained myself better. It is shaking, more or less in the steering wheel and the passenger seat. Sorry for the mix up. Thanks

Still not an alignment problem.
More like a tire/wheel imbalance.

I would suggest that you inspect the CV joint as well as the driveshaft (http://www.innerauto.com/Auto_Part/Driveshaft/) in the transfer case to the front differential.

No driveshaft of front diff on a CTS
RWD only

it was the imbalance. done for $23 for everything. Runs like a dream. Thanks
