Is it correct that the relative positions of the two rear axles of kenworth963 are completely locked? I don't know this type of truck, they are too far away from everyday life, and information on this is difficult to find. But a fully locked balanced suspension seems unreasonable, because it will cause the opposite wheel to be lifted synchronously and lose traction, which is usually a rare design on trucks. From the construction of the video screenshots, it appears that each rear axle allows some degree of independent tilt.
