Steering and Suspension
Why would a 2003 Subaru make a rubbery grinding sound when braking and steering wheel is turned towards the left?
First make sure the tires are not rubbing on the suspension
system or on a mud flap. See if there is unusual tire wear. If not,
it is likely a front wheel bearing. If the noise is in relation to
the speed of the car, this is the most likely scenario.
