Ford Mech's watch this vid!

[BadGT04]

So I thought the vibration on my truck was a wheel bearing (since it got louder with speed/etc). Tore it apart over the weekend to find the hub and bearings are fine. What do you Ford Mechanics think about the play in this?

I have a feeling it is going to cost more then what I had intended. I don't think there should be that much play in it. Good thing I have a second vehicle so I can save the money to get it looked at.

How much play is in that u-joint? The unit bearing\hub adjusts for a lot of that play.

[BadGT04]

Dirk, are you thinking that is normal?

[Dirk]

Fairly normal. But I see some play in the shaft joint and I can't tell if it's the video or the u-joint.

Generally, A bad vibration that changes with speed can be the propeller shaft needing to be rebuilt.

I can tell that the knuckle seal and outer dust seals are toast. I think that Ford calls them an oil seal. F81Z-3254-CB

[BadGT04]

Yeah the dust seals on both sides of the truck are trash. I did some research on here and found out that this is pretty common.

What is the propeller shaft?

[Dirk]

Front drive shaft.

The front oil seal (in the knuckle, the part number I listed above, takes up a lot of play like the unit bearing.

Mines just as bad with brand new wheel bearing in it so what's the fix and how hard.

[Dirk]

First thing to do is check the "Cardan joint bearing" in the propeller shaft (front drive shaft).

Check the Front shaft U-joints.

Check the Oil Seal (knuckle seal).

Check wheel alignment and balance and wear pattern. If wear pattern is cupping, shocks are bad or alignment is off.
