Hey guys I have a 07 f150 with 95000 on her.. I noticed that it seems like the driver side rear end seems to shake pretty good at about 55 to 58 mph.. anyone experience this or know what could be the problem? Thanks

My buddy who has a lifted jeep has this issue. Things he thought it could be is the hub assembly (very easy to fix) but didn't fix his. So he rebalanced his tires that were off alot!! That didn't fix it. And only thing it could be would be an alignment I would think it could be any of these three things. Best of luck to you! Hope that helps.

P.S. if it's lifted. Could be the start of death wobble. But that's worse case scenario

Start with a wheel/tire balance. It's the easiest and cheapest place to start. Have them look for an "out of round" tire while they're in there. Once that is looked at (and if nothing is found) you'll want to start looking into rearend or drivetrain issues like worn u-joints.
Alignments do NOT cause vibration problems.

Have you recently changed the differential's oil, if it's an LS rear it might need more friction modifier
