Vibration issue with 2010 Toyota Tacoma 4 x 4 after having ujoints changed at 30 mph and from 60 mph

I am having vibrations at 30 mph and at 60 mph and above after having the ujoints replaced. They became defective at 60,000 miles due to me no know about having them lubricated as I change my own oil and service what I can. My mechanic has rotated the rear joint 180 degrees and it still did it. He then done the same thing with the front joint. He is willing to change out the ujoints again with a different manufacturer, but I do not know if this will fix the issue. He did not drive the pins out to change out the ujoints. He has a machine shop that has done his for many years. I am new to this forum but I am stressed with this issue with my truck. Anyone have any ideas of what needs to be done so that I can get with him? He has been in touch with many different supports and has been in the business all of his life.

bring it to a different shop. it is not rocket science for a mechanic with a lift and protractor

and if some mechanic says 'yeah I can do ujoint and props' then it would
be working. this guy who did yours is clowntown
