Wheel shake

[Greg Ring]

I have a 2015 f250 diesel rear bed shakes at 47 to 50 mph tried balancing tires even new no difference .any ideas ?

Tires out of balance?

Had them balanced 6 different places

Jack it up and place the rearend on two GOOD jack stands. Start the engine and put it in gear. Have someone press on the throttle while you watch. Look for tire rotation not being circular, look at the drive shaft. I had my drive shaft out of phase 180 degrees and it would shake at 50 mph. This is what you have, I think.

This. I bought a new set of tires for my Mountaineer years ago. One of them was egg shaped from the factory. That took some fighting to get taken care of.

Even the tires on my Expedition had a shake at 70mph when new. They balanced out fine. It was just bad tires.

Somewhere else someone had a similar thread. Tried this, tried that, blah blah.
Said it didn't do it with a load in the bed.
