Strange vibration from the rear
I bought a 2009 f150 fx4 ( E-locker) and i have noticed over the past few weeks driving on i-95 that there seems to be a vibration coming from the rear,I dont notice it till i hit 80 almost exactly. Now the tires have about 40/100 on all 4, Could a balancing issue really cause this much vibration to the point my passenger seat shakes??!?. Or could the rear pinon angle need to be adjusted

Perhaps the balance weights on one of your wheels fell or got flung off. Seen that happen before as well as over sized tires getting a lil whacky after hitting high speeds. Def a big difference if a wheel isn't balanced and yes! it gets worse the faster you go.

I have a 2009 4x4 with almost the same vibration except mine starts at 50 mph. I had tires roadforce balanced rotated 2 or 3 times still in the rear end. So not real sure what the problem is. I'm going to put new break pads on and have rotors turned next week. If that don't take care of it I'm thinking bad bearings maybe I don't know.
