Different forces acting on axles?

Could someone who knows explain to me if there are different forces acting on the front axle as compared to the rear and if so what causes the difference. I am speaking of a heavy fiver with the equalizer system between the tires.

    Both axle are subject to the same side scrubbing issues while moving around a corner or side loading from strong side winds at highway speeds.

    The front axle/stub/wheel/tire can be more prone to damage when impacting a curb while pulling the trailer around a corner.
    .

    Braking rotational forces from the rear axle brakes tends to lift the front axle during hard braking events, enough to flat spot the front axle tires depending on how aggressive the brakes are set or poorly maintained brakes (ie. leaking grease seal/worn brake lining/etc)

    I'm sure others have their own experiences for more input.
