i have this noise kind of a vibration, almost like the noise is coming from the vibration. but anyways when i start it up in the morning i let it idle then go on my way and for the first 30 seconds or so i have little to no power steering with a weird vibration but only if i turn then it quits. also i think its my master brake cylynder but i figured id ask. when ever im not on the gas i get a shake vibration in the pedel and a loud vibrating noise and i have no idea what it is. it goes away after about a half hour.

p.s. my truck is plugged in at night and its 36-38 degrees when i start it in the morning and it doesnt do it when i leave school at 2:30

No steering when cold in morining. Change PS fluid with good syn PS fluid. Sometimes it is of beneifit to rev the engine slightly after startup to sling the PS pump vanes out and make them pump. Other vib may be u joints in front axle gone. JMHO
