To actually fix the problem you have it is going to take at least a new hub and seal(s)and possibly a new axle to ever get it to stop leaking. The hub can actually strip the spline completely out if it is run long enough. I have seen it cause the wheel to fall off too because the nut is constantly being hammered when in use when it is loose like that. Sometimes a new hub will fix the problem if the axle spline is still good enough so that when the nut is tightened there is still a gap between the nut and the shoulder at the outer end of the axle spline. This is a tapered spline and if the taper is worn off just a few thousanths the hub cannot be tightened before the axle nut makes contact with the end of the axle spline. You could washer it up so that the hub can be pushed further up the axle spline but if you do this then the hub is going to begin to rub the brake shoe return springs and make a heck of a racket and cut the springs into eventually. I have fixed a few by cutting 6 shims from hard steel banding material and placing them in the spline between the hub and axle and tightening the hub with the nut. You have to re-tighten the nut a few times every hour or so after this fix or it will be loose as a goose again in a matter of a few hours. A new axle and hub and seals is the best fix in the long run if you got the cash. Zane
