My eb is vibrating when worst when doing around 60-65 kph a little worse up hills, the vibration disappears as soon as I remove my foot of the accelerator and coast along. I also feel it at higher speeds but not as bad. All my mounts seem fine I've just put on new tyres and had a wheel alignment done. There seems to be a fair amount of movement where the tail shaft goes into the back of the trans. I went to my local auto shop to price a new extension housing bush and seal but the bloke there tells me that I can only get a bush through Ford and that it wouldn't be worn out anyway. He say my vibration would be more likely from the trailing arm bushes. I'm just wondering if anyone else has had a similar problem and if so what they did to fix it. Would worn trailing arm bushes cause vibration like this? Any help would great thanks.

The rear trailing arm bushes can cause vibration if they are worn, basically if they are worn it allows the diff to wind up causing the pinion angle to change depending if under load or not.

Thanks for the help joolz, turns out my tailshaft and uni joints were stuffed. All replaced and no more vibration.

Who fixed it and how much?

It was all done for $120
