Loose engine mounts?

[AirOlson]

My truck recently has been starting to shake when idling and letting of the brake slightly when in drive. Not sure if this means something is loose?

Pop the hood with engine running does it look like the engine is shaking around ?:help:

I took a look and the engine seems to be shaking a little bit but not much.

I believe I have slightly warped rotors, has anyone experienced this?

that wouldnt cause vibrations at idle.. how bad does it vibrate after letting go of the brakes? how long after letting go of the brakes does it vibrate? does it vibrate when you press on the brakes when stopping? warped rotors on common on 4runners but it vibrating at idle wouldnt be the rotors..

The truck vibrates just as I slightly let of the brakes. At highway speeds the steering vibrates quite a bit, so i'm not too sure whats going on?

steering vibrates at speed? a shimmy? might need the classic lug centric Road Force balance with the Hunter GSP 9700 and Hawkea adapter. Search this. Lots of threads.
maybe your rear pads are contaminated with oil (leaking rear axel seals?) and sticking to the drums?
You may have separate issues even though they are concurrent.
