Weird vibration/rattle

I've scoured through here and google to no avail. I have an 86 K10 swb with a 4in spring lift and 35s. Recently I have come to notice that when I start to flex, especially turning left, that I get this really strange rattling and vibrating going on. Not sure if it could be something in steering or a driveshaft perhaps? This was only a recent issue, it used to be just fine. Any help to diagnose would be greatly appreciated.

Re: Weird vibration/rattle

Check your engine and transmission mounts.
The flexing in one direction may be causing the engine to shift away from the bad mount, then with that shift you get the vibration transferred to the frame and the rattle may be from the fan blades swiping at the fan shroud.
