My 7050 gets a hell of a shake when moving at slower speeds and some times it feels almost like its putting power to one axle and then over to the other axle kind of a wobbly feeling. I haven't drained any oil yet to look for shavings and dont want to drive it to fast incase something should lock up or let go. Any thoughts

Is this with duals?
On a road or hard surface?
Bias tires?
Could just be tires not mounted straight on the hub center?
Also - cab isolators due for replacement...

Sounds like a tire or lack of ballast issue to me. Engaging the diff lock would lock the wheels together to eliminate the side-to-side waddle.

Its done this for a while,years actually but not as bad as it is now. I always assumed it was the tires but idk for sure. First I had 23 degree radials full of fluid, then I put bias GY dyna torque tires also full of fluid. Currently it has a set of Armstrong bias tires no fluid. Duals or no duals,pavement or dirt it shakes and vibrates. This is all while just driving around not pulling anything. I never really noticed this while doing field work.

Try jacking one wheel up next time you have it in the shop, and turn the wheel a full turn to see if it runs true.

CAB MOUNTS....ADD AN EXTRA ONE ABOVE THE BATTERIES AND TWO EXTRA UNDER YOUR SEAT.

The two extra under the seat don't even need to be bolted in place....they just sit in a pocket and can't go anywhere.

I agree with cab mounts, had a 7030 that way, new cab mounts fixed mine.
