Good news that selectro looks good. These are really good hubs actually. Everyone in 67-72 land wants the blue knob spicers but the selectros and warns are better. Squeaks in 4x4 won't be in the hubs. The hubs lock the axle to the wheel hub. Kind of like a switch. On off. The sound usually come from the outer axle inner bearing or the axle joint. So dig deeper and you will find it. Btw I like these old selectros because when it 20 below you can actually engage them with a glove on. Barry
