Little Vibration and Noise

[ManwithSupra]

Was driving home the other day and i have noticed that the road noise is alot louder than normal and a strange vibration feel on the accelerator pedal, with an odd all i can put it as a medium wirrring sound (but not ahhh its difficult to explain sounds)

 

I can only discribe it this way.

 

It feels like you are driving on the motorway @80mph and driving on the sleep drift detectors on the hard shoulder but about 60% quieter and the sames goes with vibration.

 

I am getting no real vibration through the steering wheel and have just had the wheel alignment done.

 

What do you think it may be ?

Is it the same on all roads, both normal two lanes and the highway? Could be rear alignment issue or... another lesson learned on this forum, rear subframe bolts being loose. Did you have them checked before/during the alignment? Only other thing I can think of would be driveshaft u-bolt worn or strap loose. Don't know really, just guessing from what you've said. Best of luck.

Check all 4 tyres VERY carefully for bulges, lumps or blisters on the tread or sidewalls, both inner and outer. Could be a damaged tyre or one de laminating. Jack up car and rotate all 4 tyres to look if they are "running out", basically this is to check they are still perfectly round, with no bulges.

Something i have realised is that when you go 20mph (which i dont very often) it is very noticable, there is a vibration somewhare and it is making a slight noise, however this does not seem noticable from the outside of the car.

 

My rear brakes need to be done but i should not think that this would create a vibration like this.

 

I think i will take it to miami GT on Monday for someone to have a listen and a quick look.
