It seems to me like a good, secure, locking washer would help, if not fix the situation, but again, I'm new to this.
If the threads on the axle or bolt were pertially stripped, then it would not get tight enough. But you'd probably notice it because the nut would tighten, then get loose even though you were still tightening. If the tightness feels normal, so that your bicep bulges a bit and seems to stay tight, try the washer .... it's only $0.15
