Back tire shake on my truck and not sure why

How about more information? I assume you have balanced the tires and checked for obvious things like the tire coming apart?

Tire been check and so has the rims nothing wrong there and the Axl is fine too

Check the wheel bearings and make sure your emergency brakes are not dragging.

Okay will do cause its only my back driver side tire on my truck but Im having the brakes looked at today

Okay so I just got more information my son spun out and hit a curb on my driver side with the back tire

So the truth comes out ;) Bent wheel is my guess.

What do you mean by a bent wheel cause I have all the tires and my rims looked at all and was told nothing was wrong with them and my Axl is fine

Apparently not. Have the wheel checked for runout but it is possible the axle is bent or there is internal damage to the differential.
