I have only had my 2003 Cobra for about 5 months and it has about 33,000 miles on it. It was a welcome home gift from my wife after returning from Iraq. The problems with it are; at about 3,400 RPM there is a vibraton and audible sound comming from the driveline. I have had it to a trans shop to see if that was the problem, but to no avail they said all was good. I then took it to the ford dealership and told them what the problem was. They lookedat me all crazy and said they could'nt help because they dont take cars that high in RPM. They also looked at me with the look of "what do you think you have, a fast car", very annoying. The second problem is the supercharger pulley is making a squeeking sound, very loud. I pulled the cover off and took a look, but could not find anything wrong with it, the pulley itself is not stock, but a smaller one that i meqasured out to be 3.10in and no name on the outside of it. Could this just be the belt needing to be replaced or is there more wrong than i can see? Any help would be appreciated.
something wrong with my 03

Snapper, Check out www.modularfords.com . Go the the Terminator Section there. There you will find the best 03/04 Cobra tech on the net. I think the vibe is caused by a driveshaft issue. I honestly don't remember, but I know there has been numerous threads on modfords about that in the past. Not too sure about the squeeking sound. Is the snout of the blower shaft even with the pulley? I.E. is the pulley centered correctly on the snout?sapper_mac said:
There is a SSM about driveline vibration as Dan mentioned above. Althought it is speed related more than RPM. What does the view in your rear view mirror look like at 80MPH and above? Blurry? Here is the actual SSM...
SOME 2003 MUSTANG COBRA MAY EXHIBIT A VIBRATION WHILE DRIVING. IF THE VIBRATION IS FELT AT 45 MPH AND INCREASES IN INTENSITY AS SPEED INCREASES, REPLACE THE REAR AXLE ASSEMBLY (FORD PART# 241L). IF THE VIBRATION IS FELT WHILE DRIVING AT LEAST 65MPH AND INCREASES IN INTENSITY AS SPEED INCREASES, REPLACE THE DRIVESHAFT (FORD PART# 2R3Z-4602-BA). IF THE VIBRATION IS FELT WHILE DRIVING AT LEAST 65 MPH AND DOES NOT INCREASE IN INTENSITY, BUT IS CONSTANT AS SPEED INCREASES, THEN NEUTRALIZE THE EXHAUST SYSTEM AS STATED IN THE 2003 WORKSHOP MANUAL SECTION 100-04.
