S/P G671

I have noticed the last few times that when i shut my truck off,i can hear the turbo spinning to a stop.I didnt notice this before,or just didnt listen for it.Could it be a bad bearing or is this normal?

Do you let it idle for a while after putting it in park or do you just park it and shut it down? May also be the electric fan clutch getting weak. With the truck shut off try and spin the mechanical fan. It shouldn't make it a complete revolution. If it does it is getting weak.

i do let it idle until my egt,s get down to the low 300's then shut it off.i'll check the fan clutch but im almost positive its the turbo.
