I was driving to night when my truck started shaking bad. I was not pressing on the gas but was just doing 30. I had to stop and then start moving again to get it to stop, But it would soon start up again. Does anyone have a clue to what this is. Are my axles bad? please help.

HEy,
Welcome to the forum. Your question was way too vague to answer.
May I suggest you read this:

No trucks discussed here, only Mercedes-Benz diesel cars.

Pretty vague. Did it feel like tires or drivetrain? Tires can be checked pretty inexpensively at any tire shop. If it was drivetrain, probably a u-joint or if 3/4 ton and up, a driveshaft carrier bearing. I am sure there are forums for your make of truck.
