I have a 2013 Surveyor Select with aluminum wheels and chrome center caps and I also just greased my wheel bearings. In my case there was no way around it .... I needed to remove those wheels. The chrome caps were held in place by the wheel.
Note: If you were going to adjust those brakes before your trip having them up on the jack & stands would be a perfect time to do it. I unfortunately didn't have the foresight to do them together.
