Vibration at drive line tunnel 69 mach
#11
Hopefully MyMachOne will see the post and respond.

His Mach 1 is a 1969 and I believe that he runs a 351W and automatic. I would imagine it is either a FMX or a C-4.

I suspect the yoke is in need of replacement /
I am thinking thats the issue not the tranny output shaft.
Can anyone help conmfirm ?
Hi. What engine and transmission is in your car? I have te same problem but it varies with temperature which leads me to the mount. Mine is oily but intact. Please advise. Thanks..


I had the same problem , it was not the yoke , it was the shaft bushing , I also put a new tranny mount in , use the rubber only ones. The urethane ones are to hard and do not dampen the vibration.
I can now drive it upwards of 80+ mph and have very little vibration.
