I haven’t seen pics or heard what the damage to the turbo is, but when you came here originally I could hear the blades hitting the housing under any sort of load, even while cruising. In the past I’ve seen customers come in with this issue for a few different reasons:
Housing bolts being loose.
Housing bolts torqued unevenly so the housing doesn’t seat right.
If things were pryed and forced into place I could see a housing being misaligned in relation to the center section.
All of those things would leave the wheels and shaft in balance but a wheel or both of them could brush against the housing(s).
If the shaft got bent during the prying I doubt the turbo would have lasted as long as it did, so I’m guessing it’s one of the first three.
If you’re lucky a standard rebuild plus a new wheel or wheels will fix it. If the housing or housings were damaged it may be cheaper to replace the whole turbo.
