I ordered them from Precision in Birmingham.
Looking on the internet I found info about wingfoot truck centers that some do different services and talking with them, they said if it had a shake, it was mechanical and they would find it . They changed the hanger bearings and that fixed the vibration.
I'm glad you found the right shop and got things fixed. Now it's time for a refund from all the other shops that misdiagnosed your problem. As if!!
