I have always heard how stout the axles are that come underneath the FJ-40 Landcruiser. Does anybody have personal experience with them or know what kind of axles they are? I have the an axle identification chart, but none of them match. It looks similar to a Ford 9 inch in the aspect that it is smooth around the back side (no cover bolts) and the center section pulls out. Any help and/or advice would be appreciated. I was thinking about putting them under a 1994 4Dr S15 Jimmy. Thanks in advance!
