Hi, I have a 2006 XLT 4WD. Recently I bought a tire for the rear right side at the junkyard and I've also had the REAR wheel bearings/seals replaced. I now have a vibration (not crazy but definetly there) when traveling at 60-65 MPH and over. It does not worsen with increased speed (over 65). There is no noise that I can hear. My question is if you think its the tire or the bearing. Ive loooked for answers everywhere. Could the bearing not be seated properly? Or is the tire junk? The tire is not the same as the others nor is the "wear" the same. Any ideas on what to try next is appreciated. Tks john

 

You should have bought a match set. Do you have vibration over 75-80mph? Normally a tire will only vibrate for a certain speed interval

 

Good idea. That's what im looking into right now actually. I think ill buy two new ones tho. I will check the vibration tomorrow above 75. Tks a lot
Also, any idea if the wheel bearings werent seated properly would there be a noise also?

 

Get the truck out on the interstate and see if it vibrates at 80 first. If it still does, you might be looking at a bearing it a new set of tires

 

Ill definetly do that tks
