Loose Front End

[trenchwarfare]

My pinion angle is off so it shakes the **** out of my truck. I finally bought wedges and will hopefully put them in the weekend.
My question is very general, but it's worth a shot. This has caused a lot of things to become lose.
Every time I slow down and brake my front end shakes rally badly. I put a new caliper, tie rod, and pads on not to long ago. I also have a bad power steering leak I haven't been able to find, even though I replaced both hoses. Any idea what this would be? Maybe the front brakes are doing all the work and my shoes are shot?
