Help! FreightShaker Shakin’

Could you try to describe your issue more in detail?

Like do you feel the vibration coming from one side or the other or is it in the center of the truck or is it under your seat or is the whole cab shaking? Does it feel at all like the front end?

Does it always happen at a certain speed on a rough road?

You said earlier that your tires have some uneven wear on them. They should not. They should all wear about the same. If the tires are wearing funny whatever is causing that could be your problem. Maybe you have a loose wheel bearing or your axle is moving or you're out of alignment?

Maybe you could post some photos of the wear on your tires?

When I put my truck in service I had put tires on from another truck and they had a little bit of river wear and man that made a hell of a vibration.

The new tires wiped that right out.

Also from my experience when you experience a vibration only at a certain speed that is tire or wheel related.

 

The Inland Truck in San Antionio is the driveline and trans shop to go to. Good people and they use Spicer parts to custom build shafts. They used to be known as Driveshafts Unlimited until they sold to Inland a few years ago but all the old hands stayed to still run it. I hope your local one is just as good.

 

King pins ? I had the shakes on my cascadia and shop in Phoenix took care of them . Been good ever since . With the strange tire wear it sure sounds suspension related .

How the heck would I know, you're talking to a guy that drove a '72 Pete, and I'd tilt the hood to "check the engine",,,
