So I recently posted about vibrations I was having and I thought it was my tires, but since I had them balanced and replaced and the issue stays, I realized its something else. My 15 F150 has these vibrations only when accelerating and I have seen some others post about issues with driveshafts. I changed the spark plugs, no check engine lights and intermittent vibrations only on accel not decel. Anyone have a similar issue? It feels like a sputter almost but not necessarily performance robbing. Driveshaft?

 

My last vehicle a YukonXL, I put new Firestone Destination tires on it. Had vibrations. The original installer could not find any problems. I found second place and they Road Force balanced them, found 3 defective tires, replaced them, one of those were defective. Just sayin, rebalance might not be good enough, needless to say, not a Firestone fan any longer.

 

When discount tire road force balanced all four, two were defective and replaced.
