My vr6 has just started squeaking when you turn the wheel either direction, and you can feel a very slight vibration at the same time through the wheel. It does it when it is warmer rather than colder. It's so slight you can't feel it on the move, but only when still or tight, slow manoeuvres. I'm sure it's not the steering belt. I thought it was coming from inside the car (took the wheel off and greased the horn connection and to straighten the wheel), but I now think the sound/vibration seems to be coming from under the bonnet, either inside or around the rubber boot where the steering comes through the bulkhead, but it's hard to tell! could it just be a bearing/seal that needs greasing or could it be something more, like the rack?
Cheers
