Re: 60k service?
The Grinding noise could either be brakes binding..usually a good clean out of the pads and calipers cures that..and making sure the caliper pistons move freely. Or it could be a wheel bearing on the way out, and these often sound worse on a corner as there is an inner and outer bearing..and the failing one makes a louder noise when it is loaded up..i.e. cornering. The difficulty is often identifying which wheel is doing it.
Much less likely, but still possible is a driveshaft joint failing.
No need for main dealer, any half respectable mechanic can sort these out at reasonable cost, but i'd suggest using a good independent Alfa specialist.
Yes, they use oil. Its not indicative of anything serious usually..PROVIDED you check it weekly and keep it topped up. Running low or dry may cause serious damage. Be warned and vigilant. Lots of makes of cars do this, so its not just an 'Alfa' thing
hope this helps
