i got a pgm2 axel jammed in the thread of my DNA. i measured first to see if it would fit, and it did. i guess it just got jammed. any suggestions? and ps, anyone have an original 888 for sale?

My bet is that the PGM has course threads and the DNA takes fine threads. You probably stripped your DNA.

The PGM and DNA both use M4 axles. You may have cross threaded the DNA or it could just be a tight fit. Use some pliers and unscrew the axle.
