When I do axle adjustments I get the axle snug enough so it won't move easily, but still loose enough so the adjusters will pull it. You have to start with a 'Too Loose' condition. But if you are careful and don't over adjust the tensioners, it works great. The axle stays where you put it during adjustment. Then you lower the Spyder to the ground and tighten the axle nut the rest of the way.

I found that leaving the axle nut completely loose just invites the small amount of movement which throws everything off when you attempt to tighten the axle nut.

Works for me anyway!
