Not the larger seal on the back of the brake, it's the one that's bolted against the dust sheild.. it falls right off. That one on the back of the brake is definitely destroyed, but I keep extras of those.
I didn't start until noon, so probably 7 hours today. Got both knuckles bolted back on, and the inner axle seals pounded in, then I got tired and hungry. Will finish up tomorrow, probably 3 hours tops just need to repack everything and slide it all back together.
This is the second time I've been in there, but the last time 2 years ago I didn't go as far as replacing the knuckle bearings or taking the birfs apart. Much more thorough job this time, plus I learned a couple things today. Also replaced the "groovy" inner axle I discovered last time, and am using the right grease this time..
edit: spent the last half hour reading Romer's definitive compilation on the 80 series front axle service. http://forum.ih8mud.com/showthread.php?t=78276
Very well done, Ken!! it's all in there..
