Hi all,

My 2003 F-250 5.4L 2WD has a front end vibration that starts around 40MPH (sometimes) and gets gradually worse until it goes away at 55 MPH. It oscillates the wheel a good 3/4"-1". It also does it also when decelerating through those speeds. It "feels" like the left side, but I can't be sure. When I jacked it up, I could get some movement laterally on the left wheel, but not the right. Also Noticed that the drive shaft has about 1/4" of play at the carrier bearing. Leaning towards ball joints. Any ideas?

Thanks!

 

Have you checked the wheel bearings? It sounds like a bearing issue. Do you have any uneven tire wear?

 

I am really confused reading this post. You don't mention what wheels you're talking about with lateral movement, but I'm assuming it's the rear because if there was that much movement in the front you wouldn't make it more than about 25 feet. Then you mention the carrier bearing so I'm thinking you have to be talking the rear and then you throw out ball joints and I just have no idea what you're talking about.

Can you clarify this a little?
