Truck shakes when turning

Got my truck stuck yesterday and think I may have damaged something. On the way home I was making a left hand turn going about 50 and all of a sudden the steering wheel started shaking really bad and the whole left side of the truck was shaking, a wobbling feeling. I thought I had a flat tire so I check but nothing. It Didnt happen again until this morning. Again it was a left hand turn but this time in a parking lot. I was going slow so it didn't shake as bad but it still made the same feeling. It almost feels like something is bent, not sure. Any ideas? And when it was stuck I hi centered it on the front skid plate. Not sure if that helps. Thanks!

The first thing I would do is to check that the pittman and idler arms are bolted on the truck securely, then I would check all the steering linkage points, make sure that they are all nice and tight. Are all the boots on the tie rod ends in good shape? I doubt that there is an issue on the gear box, but it's worth a look, you can never be too safe.

I don't have any pics to help with this, but on these trucks one can take a look at them within 5 minutes easy (unless it's slammed)
