I have a 4500 pound axle on my Argosy, it came stock in 1972 with the same rated axle, so a lack of available axle capacity shouldn't be an issue.
As for the overloading, you can expect a higher rate of bearing failures, brakes wearing out prematurely, broken shock mounts, tire failures, etc. Also, you may have excessive frame flexing, resulting in metal fatigue and broken frame members. You may also have an increase in exterior leaks, as the frame flexing will stress joints and seals in the skin of the trailer.
Also, the effects of overloading are cumulative. If you overload your trailer today, you may get away with it for a while, but you will be reducing the years and miles of usable life from your trailer.
