1. A system for estimating axle load of a vehicle, comprising:
an axle system including axle components, wherein the axle components include an axle, a first knuckle, a second knuckle, a first kingpin, a second kingpin, and a tie rod;
an angle sensor positioned proximate to one of the axle components; and
a controller including executable instructions stored in non-transitory memory that cause the controller to:
estimate the axle load of the vehicle in response to one or more angles between two or more of the axle components, and
adjust operation of a system of the vehicle in response to the estimated axle load of the vehicle,
wherein the axle system is free to expand and contract without the angle sensor separating from the axle system.
