Rear wheel bearing?
Just looked again, it could be the aux belt idler
I'd say it was off a pulley.
If you are unsure where it came from, I would advise not to drive it, as if from the aux pulley the aux belt could come off and take out the cam belthmm, Ok should I be worried about driving it? Drove fine afterwards for a couple of miles? Getting booked in to a renault specialist but they are an hour away now I am worried I should be getting it towed there?
since I bought the car a couple of weeks ago the steering has been heavy. also doesnt start straight away. No idea about water pump.
Now just have to work out how to get it to the garage?
