I don't know about the ceramic part only have heard about the possible turbo issue to my knowledge there's no ceramic ball bearings

interesting read. Deff learned some thing new. I've only worked with/on or rebuilt Journal turbos never had a chance to pull apart a ball bearing one.

 

Last I knew Honeywell doesn't make turbos for Ford. So considering that how can ceramic ball bearings in stock turbos enter into a Ford conversation? OP asked about known issues....not swapping turbos.

 

Totally inaccurate as to the issues.

 

from what I see Garette which is a division of Honeywell does supply the turbo for the 1st gen 6.7
see info here:
VNT DualBoost Turbochargers | Light Vehicle Diesel Engines | Our Technologies | Honeywell Turbo Technologies

 

It's not the bearings causing the issues it's the compressor wheels.

I was wrong about the turbo manufacturing done by Garrett.

 

I miss my 6.4, my 6.7 isn't as fast, but I'll try to change that

 

its deff a heck of a truck lacks some of the pick up of the 6.4 compund turbos but its smooth and reliable as can be. Actually after about 4 months riding the 2011 i had the opertunity to purchase a "left over" 2015 for about $40 more a month payment. drove in for an oil filter drove out in a 2015 Fx4 F-250 lariat 2 miles on the odomoter. Just today hit 18,000 already have my exhaust, (flo pro 4" downpipe back duals) just waiting to save up $$$$ for the tuner.
