Just returned from a 350 miles round trip. It was smooth rolling all the way!
I stopped after first hundred miles checked the temp of the hubs (just by touch), crawled on all fours and check for any leaks, sniffed around the front end for any burning smells and found nothing wrong.
I am hoping that this chapter can be closed now
You'll be fine. Now....tell the wife to "Get in, Sit Down and Shut up".
Enjoy your trip.
