    So my car is a 99 eclipse GST Spyder. 5 speed 2.0 DOHC turbo. Recently I had to pull the front passenger cv axle due to it literally coming apart turning into my driveway. I’ve tried 3 different cv axles specific to the car. On all the diameter of the shaft that goes into the tranny has been too large. A friend recommended using a 1G axle. What’s going on here?

    Just guessing, someone may have swapped in a different transmission at some point. The axle sizes and spline counts are different throughout the DSM years. My car is on its fourth transmission.

    What is the number and letter code stamped on your transmission bell housing?

    When you have that, you can look up what transmission the car came out of originally and figure out the axle type you need. Go to post #5 in this thread for some more info.

    EDIT: some additional info..... that "MUZ1" you found could be MUZT, which is the 97-99 Eclipse AWD 5-spd turbos (manufactured 7/96 to 99). But you already tried a 99 axle and it didn't work. So possibly that transmission has been apart for a rebuild and the original front differential was replaced with a 1g or Galant type or something.
    Don't quote me, but I think I read that the front differentials can be swapped around between transmissions by also swapping the spacers or bearings. This would lead to needing a different size axle than what your car came with.
