Great, just glad you got it solved.

I once spent three weeks at a truck repair shop in Livingston, MT with a different problem!

Yes - Finally out of Montana. Headed back to the West Coast. When are you all going to finally be out of Michigan? Counting the days....

Hi Sean, great to hear all is good, those noises from these old girls are tricky, you need the ears of an old guru mechanic to decern them most of the time, to not worry its a major issue, Montana is not the worst place in the world to be stuck, taking a few days at Rincon Pkwy, before parking the bus, tom lvmci...

Tom - Still have some noises and vibrations I am trying to work out...nothing is overheating or falling apart though

Hope you got your surfboard out. Looks inviting. I am jealous.

What's the latest on your vibes? There will be plenty of peeps at the rally to help listen for issues

Sean - I have been having a tough time here -- can't you change the name of this thread to "Need help troubleshooting rear axle/diff"

?

Don't know Scott. I've had a couple peeps look and have asked lots of questions. It was doing this before we pulled the rear wheels and is still doing it now. That's why I'm guessing the front wheels. Its definitely something with a wheel. Might be as simple as a sticky brake pad...its making a very faint whump whump whump that scales to the speed of the wheels.

More noticeable at slow speeds (below 20 mph) and between 50 and 60 MPH. After that it becomes difficult to notice. I had to point it out to Wifey.

I don't think its anything major. There is no additional heat anywhere as far as I can tell and that's after 6 hours of driving and shooting everything I can think of with the thermo gun.

I figure if its bad it will show its ugly head somewhere at some point but we just drove 1800 miles with no issues so I'm not super worried.

Make sure it is not coming from cupped tire/s. Spider gears shouldn't be the cause as they don't turn unless side to side wheel speed is different.

Sean,

Have you checked your tires for rocks or a bolt?

I know it sounds nuts but either makes the sound you're describing.

I've heard that sound several times and removed a rock from the treads and it went away.

A bolt that is not long enough to cause a flat will drive you nuts.

I'm a little unclear whether we're talking about the front or rear.
I assume it's the front since you hear it on the road.

If it changes with speed, it almost has to be wheel or tire related. Is a drum warped?

Sometimes the little things can drive you nuts.

Did you replace or put new tires on one side only recently?

Yes. Front right side.

Other people have given you good info but there's another thing to think about. Sometimes, you just get a bad tire. In the manufacturing process, the cord assembly can get out of line, or the "overlap" where the cord is wrapped over itself will be wrong (we had a lot of these on motorcycle tires in the '70's), or maybe the tire "rubber" gets injected wrong or at a slightly wrong temperature. What you're left with is a tire that's just out of round, or with a "bump" internally or externally, or completely out of balance -- there's no fixing these tires and no amount of balancing on the wheel will help.

Something to consider, if all else fails.
