View Full Version : Rear axle materials- good for?

I wanted to ask- has anyone used the rear axle tubing for anything? I mean the tube on each side of the diff that the axle runs through. I've never paid much attention to them, but I seem to think that they are cast iron- at least some are. Might this be good to re-use- model engine cylinders, perhaps?

The rear axle tubing is steel , cast iron would break at the first pot hole you hit.

Cast steel, then? It's been awhile, but I think the axles on the Land Cruiser are cast- something. They show all the typical marks of a casting- but perhaps they are forged-

Most common rear axle tubing, or housings on rear drive axles with a removable center differential, is low carbon steel tubing.
On rear ends with cast center sections, the center sections are usually made from either gray cast iron or ductile iron (nodular iron) for heavy duty applications. Can't say I've seen any with cast iron tubing.
