Step-by-step explanation:
The support suggested to go between the wheel arm assembly and the hydrostrut during wheel maintenance is a wheel hub assembly or wheel bearing assembly.
The wheel hub assembly is responsible for holding the wheel in place and allowing it to rotate smoothly. It connects the wheel to the hydrostrut and provides support for the weight of the vehicle.
The wheel hub assembly typically consists of several components, including the hub, wheel bearings, and other associated parts.
