    Vibrations - Need Advice

    Okay, the car has a shudder to it. It feels just like an out-of-balance tire. It can be felt at all speeds, but is more noticable at around 45 MPH. It does not vary with engine speed, only with vehicle speed. All four tires are new and have been balanced twice. The wheels have been checked and are true. All four rotors are new as well. The only other significant rotating mass I can think of is the driveshaft. Has anyone had a problem with a bent or out-of-balance drive shaft? Any other ideas?

    Could be more than the driveshaft. How is the alignment and frontend?

        The front end is tight and straight and the tires are all wearing evenly. I'll check the motor and tranny mounts, but there are no thumping noises and it definitely feels like a rotational problem.

          tires may have a broken belt or be out-of-round, that caused my problem. you say they are fine so it may be an axle or possibly the driveshaft.

              id check the DS first, check for tire wear if its alignment.

                  snatch, it may be an engine mount, or your exhaust, possibly the pipe or clamps hitting something or maybe your cat is shot.

                  i doubt its a misfire but could be possible, do you have good pickup at 40 or so miles per hour?

                    I was thinking it may be a mount so I crawled under it today but I couldnt tell. I just got a SES light so i'll know more when I get that scanned. And HELL NO I dont have any pickup, at any speed.
                    Im pretty sure its not my exhaust just had it redone with the B&B and they did an awesome install job. Its bad at idle, goes away as soon as you take off, but right before it shifts it gets really bad. Ill keep you guys updated when I get the codes scanned. Keep the ideas coming.
                    Thanks,
