Miata shudder/Vibration, please help

[FlipKing]

After leaving a redlight, it feels like a vibration or shudder, almost like somthing is in my tire, but my tires look fine. It happens when I accelerate in 1st through 3rd, and when I acclerate and let off and let it slow down by itself. Driveshaft or differential maybe?

motor mount?

Feels like its coming from the rear, but that does make sense, I'll check that tomorrow

I'm thinking u-joints

make sure your wheels are on tight....start with the dummy stuff

jack the rear up, and get someone to put it thru the gears. you will be able to see if its a tire thats wobbling. And will be able to hear the clunk, and tell where its coming from.

answer this:

Does it do it if your going up a hill, and dont down shift and accelerate? Or if your cruising at a low rpm? Or will it do it all the time?
