Will a Prothane 61604BL tranny mount for a 5.0 fit the 2.3 T-5? Also what might cause vibration going about 65mph, bad U joint or could it be the mount?
As for the vibration, I don't know. I DO know that when my U-joints went out, they vibrated at like every RPM and you could definitely tell they were shot.
i dont have any expierience with the Aerostar shafts, but i can tell you the FMS driveshaft is a good investment, Weighs like 1/3 what the old one weighs, and reallly soaks up vibrations and noise you didnt even know you had..
