Ask the driver where they feel it
A vibration on a tractor is reported as "it shakes," and that report on its own sends the search everywhere. The driver usually knows more than that, if anyone asks.
Where the vibration is felt says a good deal about where it comes from.
In the steering wheel. The front of the truck: steer tires, steer wheels, or the front end.
In the seat or the floor. Further back: the drive axles, their tires and wheels, or the driveline.
Only at one speed range. That pattern is typical of an out-of-balance assembly, which shakes most around a particular speed and less above and below it.
Only when pulling a particular trailer. The trailer, not the tractor.
A driver who can say "steering wheel, around highway speed, every trailer" has already narrowed the job to the front assemblies, before the unit reaches the shop.
Make it part of the report
Add two questions to whatever the driver fills in when they report a vibration: where do you feel it, and at what speed. It takes ten seconds and saves the shop from checking every position on the unit.
When it is not balance
A pull, or a vibration at every speed, points to heavy-duty truck alignment or a worn part. A vibration that comes back after balancing is often the wheel itself, and wheel refurbishing is offered here. The national tire and wheel balancing page covers the occasions worth asking for balancing.
