Shakes or Wobbles problem
2004 Ford Falcon 6 cyl Two Wheel Drive Automatic 116000 miles

Vibration coming from underneath of car? At speed, usually starts around 100km per hour, is intermittent. Doesn't come through steering wheel, can feel at feet and through seat. Can also do it at low speed, but not as bad. Can get so bad on freeway, I think wheel is going to fall off. Have put 4 new tyres on car, as was told tyres were out of round. Have had a couple of different workshops look at car to no avail. Spoke to Ford Dealer and was told possibly centre bearing? Driveline? Uni Joints? How can this be tested without wasting money on parts that may not need to be replaced?
Any ideas

Ok first we don't have any of these modern day Falcons in the states wish we did they are cool. Anyway they are correct it could be the driveline support bearing or the u-joints or it could be something else too. But lets stay with the most common. Now as for u-joints put the car on a lift is easiest and check for them being loose. Check the carrier (centre) bearing for being loose too and check the rubber around the bearing part itself for cracks and such too. Also spin the driveline by hand with the drive wheels off the ground and listen for squeeks and noises too if they aren't loose. Let me know what you find and we will go from there.

Had the uni joints and centre bearing checked, all OK, next had the tailshaft balanced. Vibration changed after tailshaft was balanced, but still exists when travelling at constant speed for a length of time. Vibration is from under the car and comes through the floor and seat, but not through the steering wheel. Will be getting a FORD specialist to look over all the rear suspension bushes next.
