Odd turbo noise. Vid inside.

[03XL6.0]

Had a the truck in at the dealer the other week for an HPOP repair and i got it back and the turbo now makes an odd noise between gear shifts and when i use the motor to slow down(leave it in gear and just let off the throttle)


The truck seems to run out fine but the noise makes me nervous

Here is a vid of the truck.. you can hear the noise at the 8-10 sec mark and the 23-27sec mark. sounds like the turbo is wining down or a bearing noise..

I really don't know that much to give ya a diagnosis. Have you checked your intake and make sure it seated properly? My mechanic found something had gone thru my turbo and it was making a similar noise. My filter was Afroengineered with a stock housing and a car air filter. So it was f-Ed when I got it.

if you're talking about the droaning noise, i wouldn't worry about that. it's normal on some of these turbos. did the dealer service the turbo or open it up?

Actually there is a tsb for certain year 03 turbo droan, and an update to the bracket.

Yes it's the droan or whine when the turbo comes down. I thought that maybe it was a gear whine from the trans but I makes the same noise if you free free the truck with the clutch in or the clutch out.

If you guys think its fine. I'll be happy. I pulled the intake. All looks good shaft play is hardly any.


Am I just being super paranoid to a new sound??????

Check your turbo mounting bolts, and lookup the tsb I listed, it may apply to you.

My truck is a may 03 truck. But I'll look into the tsb. I'll check the bolts tomorrow after I wake up. I'm headed into work here soon. Sound does not seem to be getting worse either


Edit I tech did not clean the turbo when it was in for the hpop repair
