Shaking rear and gear shifter shake!!!

So I woke up to a lot of snow this morning and got a load of pellets for my stove. When I got ready to go to work after unloading the pellets, and i got on the blacktop that had no snow I noticed My back end shaking up and down a lot and my automatic gear shifter shaking. Can anyone help me out as to whats going on with my Tacoma?

 

I have the same shaking in the gear shifter. As for the shaking in the rear. I would starte by checking your tires for any separation, then check the psi is the same in each tire, check the lug nuts. If that is all fine starte checking you u joints ect.

 

Snow in the wheels and tread will make the wheels off-balance. See what happens when it melts. Drive for a while to sling/melt it off. I bet your shaking will magically disappear.

 

Ok so I believe my rear driver side shock is blown, I pushed down repeatedly on my back bumper and noticed the bounce in the drivers side. I replaced the front shocks with bilstien 5100's. and was going to wait awhile to do the rear. After shacking the back end I drove to the store and it went away. My shocks werent bouncy until after I had the heavy load. And then after pushing down It went away. I know the shocks are toast so going to replace with bilstien 5100 for the rear this weekend. Does anyone have any coupon codes for toytec?
