Can anyone tell me the difference on a 2000 Ford F350 Superduty Monobeam axle or anything other than a mono?
The Mono-beam axle is a solid front axle design, as opposed to an independent front suspension. The Mono-beam can be I.D.'d by the fact that it is, well, a large, one-piece axle, just like the rear axle. The independent front instead has what looks like a short driveshaft coming out of each side of the differential, going to each of the front wheels. The solid axle is stouter but provides a much more harsh ride and cannot handle uneven surfaces and road imperfections (i.e., potholes) without flinging the passengers in the cab about as well as the independent front suspension can.
