This may be a stupid question, but I hope someone can educate me on this: I have a D60 FF rear out of a '70 3/4 ton Chevy P/U in my '85 K5; Moser 30 spline axles, ARB, disk brakes. Went in to change something in the e-brake setup on Sunday, and as I take off the hubs (I needed to get to the bolts that hold the caliper bracket on), I notice that the spindle area is almost dry, and the wheel bearings have no grease in them (they were serviced last October, and I haven't driven much since then). The bearings were a bit lubricated with what smelled like gear oil. Maybe I'm not getting this full floater thing - my question is this: are the outers supposed to run in oil, or bearing grease? The seal at the hub was replaced in October, looked good to me when I inspected it on Sunday. No idea where the grease went, no obvious drips/leaks at the hubs, no oil/grease on the brake disks. I have an aftermarket cover on the diff, with a higher-than-stock fill plug. When I first filled the diff up to the new level, the gear oil came out at the pinion seal, so my mechanic suggested I stay with a lower stock level. Breather tube is on the driver's side axle tube, and it is not plugged. Is the gear oil supposed to be in the axletubes? Sounds all confusing, I know, but maybe I'm dealing with more than one problem here. Hope someone can clear this up for me, any info is appreciated, thanks, michael.
