I did pull the turbo and indeed, the power steering whine I have been hearing slowly getting louder for the past 20,000 miles has been confirmed as turbo bearings (bronze or brass bushings actually).
I took my time, cleaned everything best I could, (Sea Foam worked best on the aluminum) scraped as much of the carbon off the exhaust side impellar as possible & wire brushed the heck out of it.
My VGT was still working, i just scrapped it with a razor & wire wheel as well. The unison ring is tough, I block sanded that with 180 grit. Put it all back together using 2,000 deg anti seize. The Turbo Rebuild Kit I bought from Midwest Turbo Connection.
I will say that Midwest turbo answered my questions to customer service with a quickness and eagerness to make me fully happy with their product. Rare
The kit was $144 delivered. It was also the only kit that has the 5 "O" rings included for the turbo/VGT activator that I found.
I did see alot of upgradeds offered for a 360deg thrust washer over the stock 270deg one, but I had virtually no wear on mine with 215,000 miles on it. The bronze bearings however were subsantually F***ed UP!
The only teardown issue I really encounted was the Exhaust side plate that had 3 screws in it. 1 came out, 2 broke. Of those 1 came out with an easy-out, the other I had to drill and tap.
I took many pictures at teardown, followed a you tube example by Diesel Tech Ron & Various others as well, but his is the best site I've seen so far.
After install I pulled the FICM Breaker from under the hood and cranked several 30 second intervals until my Scangauge showed 1500 or so on the ICP.
Started up great, but the best part was the result.
NO MORE WHINE!!!!! Also, I have been replacing Injectors lately (I still have 3 of the original 8 running) due to allot of missfire as well as smoking especially during throttle up. All that went away as well. What a bonus that was.
I put an IPR "O" Ring and Screen Kit (Alliant, Part#AP0035) in while the turbo was out and easilly accessable $36 and a Turbo Mount/"O" Ring Kit (3C3z-9T514-AG) $11. Thru Xtreme Diesel.
Finding instructions online about anything Turbo & 6.0 related is evidently "Top Secret", But I did find this thru "RiffRaff Diesel"
Hope this helps. No special tools of any kind needed beyond a torque wrench and easy outs. Real happy with my result no doubt. I'll be glad to help as much as I can offer.
