At the ends, Rockwell axles are pretty much the same as any Dana/Spicer axles, only with larger parts. Dumping the drum brakes saves 160 pounds per axle. The front backing plates simply unbolt from the knuckles. The drums attach to the hubs with bolts and the six wheel studs. You can pound out and reuse the studs without the drums. If you're real butch, you can use a pipe wrench to remove the hub nuts; otherwise, use 3-inch eight-sided NAPA socket number M-1907 to disassemble and adjust the wheel bearings.
