Thank you for all the excellent suggestions. As soon as I return home I will have the hub, bearings and calipers inspected. And for all you BITOG's I'm running Mobil 1 High Mileage 10W30 topping off with Mobil 1 High Mileage 10W40. Fram Ultra Guard 8A remote filter. Engine has consumed 12 oz in 4,000 miles. Planning to change when I return home - about 6,400 miles.
