Thanks all. Tonight I have replaced the studs of the left side. The outer cone bearing shows some wear, but the bearing races inside the rotor seems shiny. I have ordered parts for both sides of the vehicle to be sure. Tomorrow the bearing and sealing set would arrive. I assume that it is normal for the nut of the wheel hub(fix bearings) to be hand-tight? For me the best option was to order the wheels from Europe. I have ordered a steel set of 7x15 rims. Then the car will drive around again soon. Yes I did also like the aluminium style wheels. Too bad that a broken one has gone. But good to know it is an mopar type wheel. If someone is interested in the rims you can ask me. If I am close to the car in Belgian, I can always sniff around for stuff.
