I can understand your sensitivity to squeaks, rattles and bumps I am the same way. First, the only kind of tire balance that will work well with your car is a Road Force balance. Its a bit more pricey but gets a lot of vibrations out of the wheel. There have been problems with the OEM brakes having a slight pulse when the brakes are warm, there was a TSB about the problem and new OEM brake pads are available to correct the rotor warping. Replacing the rotors on the 03 DeVille not too costly.
As for the vibration you are feeling, there again were several TSB issued in 03 & 04 about the problem. Something to do with a drive shaft balancing and other fixes. Problem is...not covered under recall. If you still have the original warranty or the extended warranty take it to a Cadillac dealership and they can fix it.
The 03 DeVilles are great, most of the "bus" from the 00-01 models were worked out by 03. The vibration, SWP Sensor and the CSP Sensors are the only areas that I have had to address.

Thank you, powerflt, for your advice! The technician who noted the pulsation in my brakes did say that it happened when they were warm. Still, as far as I can tell, it's barely there, if at all, so I would say at this point my main concern is getting the cruising-speed vibration fixed.
It's interesting you should mention road-force balancing because that was what my Cadillac dealer did to my car four times with my old Michelin Symmetrys but to no avail. The Goodyear shop swears that the new tires are in balance; I'm going to have the dealer double-check this but my strong feeling is that it's something other than the tires causing this vibration. I can't imagine it's the brake rotors, especially since the car just rolled over 18,000 miles and even if the rotors were the problem, I would think that I would only get the vibration when I apply the brakes. The vibration happens when I'm going down the highway.
I've been doing some research on my own into this issue and have come up with some possibilities to go over with the dealer when I go see them on Monday, July 9th. I'll be sure to mention the TSB regarding driveshaft balancing about which you wrote. Thanks again for your input and if you or anyone else has any ideas, I'm all ears.

Well, I took my car to my local Cadillac dealer on July 9th. I finally got it back on the 20th. They looked at the wheels and tires, swapped wheel/tire combos from other DeVilles on the lot, checked out "anything else that might make it vibrate" and finally ended up putting new lower control arms in the front end. The service manager said that there was a TSB on this; he also stipulated that the TSB itself stated that customers may only notice "incremental improvements" in the vibration by replacing the lower control arms. Well, to call the improvement I've seen "incremental" would be rather generous. Bottom line is, I still feel a vibration in the steering wheel - to the degree where I can see my wristwatch shaking on my wrist - and, to some degree, in my legs and backside - and I don't drink caffeine so I know it's not my nerves! During a road trip this past weekend, my front-seat passenger said he didn't feel anything so I guess at least my passengers are comfortable and that is one of the reasons I bought the car. I just can't quite bring myself to beleive that this is normal behavior for a car like this. The service manager said that he has been in a number of other '03 and '04 DeVilles that do the same thing, though, so perhaps it is. I still love my car. I think it's great looking, luxurious and prestigious, and, vain as it is, being seen in it and being able to say I drive a Cadillac makes me feel good. I've considered either trading it off or selling it but to tell the truth, there's really no other car out there I want, at least not one that I can afford. Additionally, I do appreciate all that my dealer has done; the car is out of warranty but not by much and so with GM's blessing, they were able to take care of all the work they did at no cost to me. My salesman even set me up with a loaner at no cost. I am indeed grateful for all that. I suppose now I'll just have to decide whether I want to get used to it and live with it or not. If anyone has any other ideas, suggestions or thoughts, I would welcome them. Thank you.

hi, i am going through this same thing you are.its august 1st 2007. vibration at 60-70 mph. my next step is to replace one more wheel that is bent.i have a 2002 deville dts. i can only hope that this solves the problem. i put brand new michelins on last week,two new struts( one strut was completly blown) one motor mount, tie rod end etc etc etc. i will not be able to keep this car if i cant get this problem fixed. my last deville was a 1997. that car was a dream to drive.you could not tell the diffrence between 60 mph and 90 mph.well, i will remember its just a car,but it may be just someone elses car soon.

Let us know how it goes. I have not been able to lose the vibration, it is slight but still lurking in there. I have not had to do anything with the struds, tie rod ends or rims, they look good. My 03 DTS heads to a new dealer across the river in Iowa next week to see if a fresh perspective will solve the issue.

Also, when you visit the dealership tell dealer about TSB 000310007A&E,1312011 and 3249. All deal with the vibration problems you are experiencing. Another option, check your front right wheel hub for wear and raise your tire pressure to 35-38 psi and see if that helps.

Hello everyone, I am new to the Cadillac world having just purchased a 2004 Deville DTS. what a great car. I did a lot or research read all the horror stories about the N* but I am still glad I bought the car. I was scaning thru older post's and noticed everyone's concern about oil consumption.
The reason the N* uses oil is because it is desinged that way. The N* is made to operate at high speeds all day long so the cylinders have an agggressive cross hatch pattern to keep oil on the cyl walls to keep the pistons well lubed. Now if I could just get rid of the vibration at hwy speeds
All would be well. I'll try some of the things I've read in these posts and see if anything helps.

Wow...its been 27k miles and the Ventus HR II tires I put on the DTS last November 06 are starting to show some wear. The rear tires are cusping on the outer edges and the rotations are not doing anything to even out the wear. These are unidirectional tires and can only be rotated front to back same side. Time to have the rear wheels looked at for alignment. Road noise has increased a bit, however, that may be due to me running them at 34 psi for better MPG rather than the 30 psi Cadillac recommends. Over all, very nice tires and great handling on the interstate and secondary road's switchbacks.
