Route 66 trip

Well today we made it to our furthest point. Visited Russell's truck stop and viewed their museum.been there before but nice to revisit.
Went to Cadillac ranch and let grandson do some graffiti work.
Went further east and found the bug ranch. Never heard of it.
Went to museum in Elk city and was nice.
Will start heading back to Louisiana tomorrow.
In New Mexico I noticed that I have a bearing going out on rear end. Can't tell if it's pinion or carrier.
Checked the oil and it's good. It had gotten louder thru the day. Cross my fingers and keep it under 60
