Based on what you’ve said and photos, the right side turbo is not getting oil on the pressure side and/or the return/drain is blocked. Either will cook the shaft to failure.

Note that there are two wheels in a turbo. The exhaust side is the “turbine” and the intake side is the “compressor”, so when you talk turbo make sure to use the correct terms.

Ok, the damaged compressor wheel(s) are caused by some debris in the intake side hitting the wheel UNLESS it happens after the shaft failure.

You said the suspension broke(?). What were you doing to cause that failure. It sure sounds like you’re beating the sh*t out the truck without taking care of it properly. Maybe you’re just trusting your “installer”? There are likely two problems causing the turbo failures that are overlooked by your technician/parts-swapper(s). When a vehicle sits for a long period of time, it invites critters of all sorts, especially mice, to build nests and bring their food into it. Nut shells and other hard items will trash the turbo compressor wheels.

I recommend starting over with the troubleshooting process with someone who does more than swap parts for a living. That leaves out most shops and dealers, so maybe just do it all yourself.
