Bad vibration when turning

[Dmarstroker]

No matter how fast or slow I turn there's a vibration that you can feel through the floor board, and it seems its coming from the alum. DS. Any ideas what to check? I know I should check the u-joints, input shaft, and trans mount. Does anyone think the pinion angle could be off?

Your pinion angle shouldn't be off with bolt on Upper and lower control arms. It could be off if they are adjustable. Now the fact that you have the vibration when you turn makes me suspect the steering linkage hitting the driveside header. Mind you, you would feel that in your steering wheel. Check to see if when you turn if something is touching the engine or drive train somewhere.

Another question would be does it vibrate when you turn your steering wheel while the engine is running but you are stopped?

No it doesnt vibrate when Im at a dead stop with the engine running. My U/L control arms are also adjustable. Do you have to have a special tool to measure the pinion angle?

basically its just measuring an angle. I'm sure they make some magnetic based protractor for measuring the angle.
