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!

 

Make sure that wheel is torqued to spec.
