New Noise- Posible Turbo?

Fenner408 · Aug 18, 2012

Yesterday day I was driving home and got on it a bit after turning a corner. I was accelerating, boosted 25-30lbs, every shift it sounds like something vibrates or grinds real quick. I also heard it when I hit larger bumps while boosted. Yesterday before I heard this for the first time I took off my traction bars to repaint them, but I can't imagine that would change much unless a carrier bearing or pinion bearing is causing it. To me it sounds like it could be a compressor wheel contacting the housing, but I wouldn't think it would do that when I hit a bump. Any ideas guys? I haven't really had a chance to diagnose it yet.

I seriously doubt its the turbos but Id take the intake off and check just in case.
If they hit, youd know, because they would be trashed quick.

Id check your downpipe, exhaust, and traction bars.

Did you re-adjust your traction bars?

Could it be a little axel wrap and the u-joint hitting the exhaust? Would make sense while you are "boosted". I don't know all my technical terms but look at that little donut on the front of the rear diff, see if it's rubbing anywhere...when I had my lift on I didn't have them adjusted right and it was rubbing there
