Turbo is most likely dying?

So, my turbo started making a high pitch squealing noise more noticeable at higher boost levels. It still makes boost like normal, and I haven't noticed a loss of power just the new noise. Also, when I shut the truck off this morning, as the turbo wound down, it made a sound I would associate with a starter going bad. It sounds horrible. I haven't started the truck since then, but it makes me think it's about to grenade on me. The truck is a 2005 F-250 CCSB. Has been fully bulletproofed, has a 4" Turbo back straight pipe, and an SCT Livewire TS+ for monitoring and programming. Also has 215000 miles on the ticker. I tow a 5th wheel with a gooseneck adapter every so often and a Kubota tractor along with some other lighter loads. I'm thinking I'm just going to replace the turbo altogether, but was think about spending a little extra money to get a better turbo. I want to keep my towing ability, but also like to have fun and go fast from time to time. I don't have any plans to upgrade the fuel system anytime soon, but if I did I wouldn't go with crazy injectors, 155 or 175 at most. Any advice on which route to go would be appreciated. Thanks in advance.

I believe a repair kit should do it if you fix it soon enough.

I'd take the intake pipe out and feel for play on the wheel. Check if the blades are indeed touching the housing. If they aren't a rebuild will probably save it. If they are you can get a new upgraded wheel, or a new turbo. KC turbos is always a good stop and they have quite a few options that will retain towing ability.. @peixinho

When peixnho replies, his shop can help. I thought it was Phoenixho though. If you're looking for a reason to get a turbo, this could be it.

I'm relatively stock and would like to see lower EGTs. A turbo in some cases lowers temps, other cases the same turbo won't. Yearly inspections make a turbo back straight pipe not an option. I'm replacing an exhaust manifold because it's leaking, and most people report this bringing EGT's down. Afterwards if temps are higher than I'd like, could be a turbo myself, if mine were looking like it was going to go, I'd get a new the turbo sooner than I thought.

I think it's the bearings that are toast, not really sure though. I had told myself that if anything happened to the turbo I was gonna replace it instead of rebuilding. It's not a bad truck at all and I plan on keeping it for the long haul, at least another 5-10 years and want it to be as solid as possible. I was mildly researching the powermax prior to the current issues, but have heard that some people are seeing slow spool times. Was worried that would affect towing. A lot of posts I've seen show people recommending the KC turbos, but I didn't know if the extra 300-400 over the powermax was worth it? Considering the powermax is already about 300-400 north than a stock turbo?

I had a shop install a powermax. Way too loud for me. Two weeks later I replaced it with a KC TurboTax Stage 1, and immediately noticed a big difference. Quicker spool up and just smoother as you stay on the throttle. Very pleased with it highly recommend one. The pmax is listed in the classifieds.

KC Stage 2 R. This is the only turbo that pulls like a madman and still spools like stock. I put my stock turbo with a billet wheel back on, and it runs great, but my egts are higher, and it falls flat after a decent bottom-to-mid pull. I can get on a freeway onramp and merge with traffic at 65 pulling 9k trailer. But egts will hit 1400+. With S2R turbo I may hit 1300+ and be passing traffic.
