Can any off you give me a lead on what this might be. Driving the car from cold all absolutely normal but when fully warmed and perhaps half an hour into a trip I get a front end rattle when going over bumps, eg "sleeping policemen". It's not suspension as all this has been checked with new lower control arms and bushes fitted etc.
Also I've noticed the coolant expansion tank is fractionally below minimum. No sign of any leaks or tell tale drips on the garage floor, but could this be connected through a radiator issue perhaps? I didn't check the coolant level after the last service so it could have been at this level then. Water temp gauge is normal and no warning lights have come on at all.
If the coolant issue is unrelated, I can get that fixed but it's the niggling front end rattle over bumps when fully warmed up that I'm struggling with.
Any thoughts would be really welcome.
Thanks
Chris
