fehlbie Donating Members 142 Member For: 15y 18d Posted 21/04/13 01:46 AM Share Posted 21/04/13 01:46 AM Need some help.I have just fitted an aftermarket upgraded tailshaft from sydney driveline services to my FG XR6 turbo.The original bolts that hold the tail shaft to the diff, that have the plastic weights could not be used as the uni joint is now too big for me to get the bolts in and the plastic weights.So I have used some socket head bolts instead.Now I get a bad vibration at 90km+ under acceleration and deceleration.Does the tail shaft now need dynamic balancing by Ford?

fehlbie Donating Members 142 Member For: 15y 18d Posted 21/04/13 10:45 PM Author Share Posted 21/04/13 10:45 PM Yeah the pinion yoke was changed to a 1350 uni and a flange. I will call my driveline guys and find out what I need to do. Link to comment Share on other sites More sharing options...

Seeing as the flange is new I assume its pretty smooth? Your local dealer could try using alloy wheel stick on weights on the outer surface of the flange at the points indicated during the balance procedure... Providing it doesnt need crazy amounts of weights and the weights stick ok it could work... Could also turn the tailshaft one bolt over on the flange until the closest balance point is reached requiring the least weights possible, will be time consuming but could work well...

I've heard the vibration problem stems from the center bearing being to rigid. Link to comment Share on other sites More sharing options...

If so have you made sure the centre height is the same as the oem bearing?Benny. Link to comment Share on other sites More sharing options...
