There is no torque value for wheel bearings on 124 and 201 chassis that I'm aware of. If wheel bearings are set to 0.01-0.02 mm according to factory procedure, there will likely be some very small amount of play with the wheel & tire installed. That's the ways its been on the wheel bearings I've done on these cars. I've pulled the hubs 45-60Kmi later and the bearings look like new. If the bearing is too loose, but the factory procedure was followed it might suggest a problem with a worn spindle or some such. Better to err on a bearing slightly too loose than slightly too tight. The washer behind the lock nut should be stiff, but moveable with a screwdriver. The wheel probably shouldn't make a "ching-ching" noise when its rocked.
