AUII 1 Tonne Ute Vibration - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

I have a one tonne AUII utility which vibrates at approx 90-105KM/H. The drive shaft has been changed for a new one and the wheels and tyres are OK. The diff angle seems to be OK. I don't carry loads heavier than 500Kg but the vibration occurs at any load. The ford dealer has given up! Any suggestions?

That sort of speed is either wheel balance, or a bent axle. I would lean towards balance (despite them being "OK"), unless you have hit a gutter or two......

I had the same problem PDC,except ive got a styleside au2 ute.I had new tyres and alloy rims and it turned out it was the tyres,eagle ga plus.I went through all the suspension ,tail shaft etc with the dealer ,they even put chocks under the leaf springs at the back to change the angle.2 years i put up with it.Then the tyre place i use re-balanced the tyres and when they spun them they looked all buckled .New tyres and a standard balance, its now spot on.Ive been told goodyears and dunlop are known for it.Hope this helps.

Thanks for your reply. It seems that I have done everything you did. I have recently had new tyres put on, Toyo HO8 light truck tyres, but it is exactly the same as before. The vibration does not seem to be coming through the steering. The ford service bloke agreed that it seems to be something in the rear. How do you tell if the axle is bent? Or more to the point, how do you bend an axle? I haven't hit any gutters that I remember. The wheels don't show any sign of damage.

Yeah, sorry about the 'hitting a gutter' line....... It's the most common cause though.
To check for a bent axle, jack the car up and spin the wheel. You need to check for 'runout' from side to side. At the same time you can check the tread for 'runout' up and down as you spin the wheel.
