I had the same issue and had to use a parktools SPA-2 Spanner to help get the adjusters off. Turns out , if you tighten the axle nuts too hard which you might if you don't want your axles to slip in the dropout, this over-tightening puts a lot of pressure on the supports (those spacer things that butt up against the frame or fork). The part of the spacer that contacts the axle then deforms the axle threads right on the end. Now that its deformed, you might be able to adjust the tension adjusters a few degrees but getting them off all the way for a bearing swap means stripping the adjusters and damaging the axle. If the threads were milled down at the beginning of the axle then this issue would not happen.
Thats what happened to me and I dont feel like buying whole new axle kits and adjusters for 80 pounds so yeah..
