2007 F 150 XL, 4.2 V6, 140K miles
Hello Ford Techs. LTNS.
Back in June 2017 I had new tires put on my truck. I noticed a vibration in the front end ONLY at 50-53 MPH. Actually, it's more pronounced at 51 MPH.
I brought it back to the tire store and they checked the balance on the front tires. They were still balanced ok. So, they switched the front tires from side to side and went ahead and re-balanced the rear tires while I was there. Only 1 tire needed to be re-balanced on the rear.
So, off I went again. As I approached 50 MPH, here comes the vibration again. I do know this for a fact, that the previous tires NEVER gave me any problems. I had to replace them because they were showing signs of dry rot. They were starting to get cracks in them.
Anyway, I was thinking that if they switch the front tires to the back, back tires to the front, and the vibration stops, it can only mean 1 of 2 things;
1) A bad tire.
2) A bent rim.
