I have a 73 Datsun 1200 pickup with a heavy vibration. the vibration is only when I gear to 4th gear and when I'm at speed and i put the car to neutral its even worse. I've fitted a new prop shaft, done the t-housing bush,put a new clutch, replaced all the mountings, put new tires, new inner and outer tie rod ends, everything has been replaced but the vibration is still there. I've spend thousands on the car but the vibration is always there.
I've even tried to re angle the shaft but that also did not work.
is there any thing else that can cause this heavy vibration???
I don't know what else it could be.
I'm not to sure if my Datsun is a 520, 521,320 or so!!
Does some one know what else can be wrong??
