Vibration

[Tazman]

My truck has developed a vibration that starts at 55 mph and is a little worse at 65.Tires are balanced and alignment was done a month ago.Two of the tires are new and the others two years old.It is mainly felt in the steering wheel but can also be felt in the seat at times.Any ideas on what could be the problem?Thanks

I have had wheel bearings cause those symptoms as well as warped rotors believe it or not. 

[Tazman]

I replaced the bearing when I did the rotors and brakes two weeks ago.

Is this a new vibration?

[Tazman]

Yes

[zieg85]

Loose wheel bearings would be the first place to look if it were me...

[Tazman]

I will check the front first and see if that is the problem.Thanks

weights can fall off.

[zieg85]

weights can fall off.

New tires can be slightly out of round and still be in balance.

[Irish_Alley]

since its a new problem i would think something had to change, a weight fell off or busted belt

[Tazman]

The tires where just balanced yesterday .

The tires where just balanced yesterday .

would of been good to know lol
i would swap tires front to back, back to front and see if the vibration follows

[Tazman]

Did that already after the first balance on Friday.Had three year old tires on the front did a swap front to rear and balance,went for a drive with no change.With that I ordered two new tires to replace the three year old ones.Put them on yesterday and today was the first time back to 55 and over and the vibration is still there.I will check the bearings and go from there.Thanks

We need to know when all of this started?  Before the tires as in it has always been there?  Or did you change something and the vibration showed up after that.
