I'm doing some work to prep my truck before it goes in for a safety inspection, and I found a whole pile of thick, black grease in one of my rear drums. Clearly that isn't good, and neither are all the springs that fell out, but I can handle those. I'm trying to figure out where all that grease came from and what seals/orings i might need to replace.
If it helps the code I pulled off the axle tag is:
S 128 N
55 10 2 6E3
The truck build sheet from Ford says 3.55 gears with limited slip, and I'm assuming it's a 10.25 full floating axle. The chilton manual I have for it shows a diagram with a seal behind the inner bearing (hub oil seal) and an oring between the hub nut and shaft retainer. I'm not seeing any traces of gear oil in there, so I'm doubtfull that the hub oil seal is gone, but at the same time I can't see how grease could get past the oring and into the drum.
Maybe I have a semi-floating axle and I'm missing something, but if someone could chime in that would be awesome.
