I installed some OHLIN coilovers at the weekend, but noticed a humm/slight vibration on any sort of right turn above 45mph, i did not have this noise before, the car is now lowered 25mm as per ohlins recommended specs. Their is no rubbing etc that i can tell, the noise seemed to go away after i gave it a few hard turns around some corners but it seems to have come back again last night, and im not sure what it could be!

Could it be a wheel bearing? even though i never had the noise before?
Could it be that i have managed to put the left wheel on the right hand side and its unbalanced the car?
Could it be my prop shaft?

Im really not sure what it could be, only thing i can think is when i was taking that side shock off i had to maneuver the hub a lot more with the top wishbone disconnected, could i have pulled down on the hub too much and damaged something?

so to recap - Noise above 45mph, front drivers side wheel, humm/slight vibration in wheel, no idea what it is!

Have you bent one of the backplates so its rubbing on the disc, I did that recently on the wife's Civic when fitting brake pads and it caused an intermittent buzz,
Just a thought but its easy to check and rule out.

When the noise happens, do you feel it through the steering wheel at all?

Define198

Yes, it is felt through the steering wheel, as soon as the noise starts it is felt through the wheel.

that is a good thought, i know i had held of the backplate, but i did look and it did not seem to be touching anything when i had the wheel off, although i dont know what to look for really.

Something is touching the steering column then, most likely the manifold. I *think* lowering will reduce an already slight gap between the two.

Mine did it but when turning left, Performance AUtoworks put a shim on the passenger side engine mount to move it a few mm which so far seems to have cured it.

did you have the noise at any speed though? or only above a certain mph?

S2KIP

It was only when there was load on the front and and I was on the throttle.

Define198

mine is fine under full throttle, and does in fact seem to get less noticeable at higher speed 60+ i went for a meet with 3 other s2000's around some country roads last night and i could not even remember noticing it in the twistys, so im unsure if it would be something catching the steering rack

Why do things always seem to go wrong lol, i fixed the suspension ready for the MOT in 2 weeks time, and now i have another problem, possible wheel bearings, at the cost of around £100 each + fitting

You will be able to see if it's the steering column, easier from underneath the car though.
