so im trying to narrow down what the culprit of the shaking is .. definately shaking through the steering wheel and also feel it in the seat ...

rear tires need to be balanced..
looked at the transmission mount and it has about an inch of up and down play .. rubber not broken .. i can also post pics

also the front left tire has a tiny bit of play when i pull / push from top to bottom of the tire ..

or could it be the rear shocks ??

so confused and if any of you all have had the same problem please try and help me ..

fix what you know is wrong with it first like you've listed, then go from there. Usually these minor shakes are a bunch of little things all combined.

We are talking little shake here right? not death wobble?

lawikfors

real fast paced shake . i wouldnt say death wobble tho..

how does that transmission mount look ?

Time for a new transmission mount there should not be that much play.

Then just how fast are you talking here

Most often out of balance tires will have a speed where they smooth out.

Ain't that the truth. And lawikfors also keep in mind that these things can all be inter-related.

In my case I had been chasing a shake and braking surge for about a year. Got to the point where it felt unsafe to drive. I'd have the rear drums turned, and it would drive pretty smooth for a week, then the problem would return. Replace the front rotors/pads, same. Then the wheel bearings, same. I could also tell that it was wearing my tires unevenly - the pressure surging in the braking system was causing the tires/rotors/drums to all wear unevenly.

Finally I decided to take an entire weekend and do all of this: Front wheel bearings/races, rotors, pads; rear drums, shoes; New tires/balance on all wheels.

Problem solved. Smooth as glass for two months, much more stopping power. Even cured the wandering that I had prior to this, that I thought was unrelated. If you do change out your wheel bearings make sure to set the pre-load per the FSM. I'm pretty sure the whole thing started with a wheel bearing that was too tight - but I'll never know for sure. I do know that last time I did them I just "eyeballed it" on the preload because I didn't have a spring gauge at the time.

I'm fighting these kind of shakes too. Mine occur more frequently when I have barely any gas on it and the truck is freewheeling like if I'm going down a hill.

It used to be worse because I had some messed up rear brakes. At first I noticed that my parking brake bell housings were completely seized and one was engaged a bit. After breaking that loose a LOT of the shake stopped but not all. It was just one part of the problem. Redoing the brakes completely seems to have helped more but my drum seems to wobble a bit and likely needs replaced. I'll take the drum off in another couple hundred miles and see how the shoes are wearing.

I KNOW I need new wheel bearings because I can hear a high pitch noise coming from the rear of my truck when I'm close to a median wall and can hear the sound reflecting back. I'll replace them all as I can and rebalance the tires when I'm done.

As he said, it really seems to be a sum of many things so if you can knock one out and drive it for a LONG time and hear some benefit, then you know you're on the right track. Week to week is too short, as a lot of these problems seem to be very much related to road conditions and loading conditions.

have you replaced your rear shocks . ive heard that those go out on these pickup all the time and start to bounce the bed around depending on speed and road conditions

If you're feeling it in the steering wheel then I say it's definitely in the front end. You also mentioned there's a little play when you move the top/bottom of the wheels in and out. That's a classic sign of worn ball joints. Check your tie rod ends and the rest of your steering system too and see if you have any more play anywhere.
