Vibration on Cerbera
Discussion
Help!
When i go over 70mph in my Cerbera, there seems to be a vibration with the whole car, as if the wheels are not balanced. I have had the wheels balanced (vibration cuts in about every 3/4 seconds)but cannot drive through it!
Thought it might be unbalanced prop shaft...any ideas would be much appreciated.

iirc the props are a trt type, which means they have a rubber bond in between the 2 parts of the prop. If it degrades it can cause movement and throw the balance out. I may stand to be corrected but think they use a trt prop...
It does sound to me like a prop, maybe diff mountings too.

I have exactly the same thing. Have had bushes etc. checked. Work in progress. If I manage to cure it, I will post on here. Would you do the same please? It's driving me

Could be wheels (if spiders, highly likely - balancing only balances them 
). Check the prop and also check that the engine is sitting on its mounts properly. I had some vibrations in my 4.5 that proved to be related to the engine and gearbox's misalignment.

Update: vibration sorted - changed the front wheels (which don't appear to be visibly bent if spun on the car) and whilst it's not quite perfect yet, the difference is enormous! Can only assume that one of the wheels is bent in some way - albeit slight, will get them tested. Just wanted to feed back! 
Although this thread wasn't originally posted by me, has been very useful, thanks for all the advice!
