850T5R Car resonates
I have a 850T5R auto estate which I am bringing back to full life. We re on the road and going very well, but above 45 mph whenever I put down any power, the car resonates. Its like that noise where both back windows are open. Do they all do that.
Any ideas. I have good Torro tyres, the geometry of the steering has been set. |

What exhaust is on the car? On my T5r, I have a decatted and de-centre boxed exhaust and that fecker drones like a beast at any sort of speed.

Is it a drone or a whump whump whump type of noise. A drone would point to bearing or diff and whump sounds like suspension related. If the tyres are fine and balanced, you might want to check the steering arms and the wishbones.

TMA exhaust
It has a TMA exhaust which was on the car when I bought it and in new condition. It does not feel like suspension as the car will make the noise in a straight line on a flat surface.
You can almost feel the revurb through the steering but its not obvious. |

Has it had a poly bush/es fitted to the engine stabiliser?
As that will transmit engine growl through the bulkhead and steering especially under acceleration. Personally I like it and my car is fully polybushed, but if it has and you dont like it swap it out for a rubber one.

Perhaps he means Toyo tyres, also maybe means a TME exhaust.
I have a TME system on my S70. Lovely bit of kit but it does drone a little. Pretty tricky to fit as it's in many pieces, maybe touching the underside of the car somewhere?
