The 2003 Ford Focus's turning circle is 34.3 ft..
Not enough info. What kind of noise? Coming from where? Under what situation(s) does it occur?
Questioner gives no indication where the noise is coming from, but it COULD be an indication of a failing CV (constant velocity) joint.
Fuel filter...
wheel bearing?
Front hubs my be wearing out.
A 2003 Lexus with an intermittent grinding noise might mean that there is a tire rim rubbing on the brake disk. It could also mean that a tire is rubbing on a fender wall when turning.
More than likely you have a defective left front wheel bearing. Inspect the bearing and also inspect the bearing on the right front. Inspect your brake pads if this is not the problem.
if you have a bad axle they will usually make a clicking noise when turning
Starte could need a shim.
Are you sure the noise isn't in the front. Sounds like a right front wheel bearing,which is a common problem on these vans.
Are the belt and belt tensioner in good condition? Are the tires properly inflated?
