What did you do to your truck today? Chapter II

[blf]

So I flushed the brakes last night. The brake fluid looked terrible. I got new clear fluid at all 4 bleeders now.

In back I took the drums off for a look, one side is mucked up with 'grease' -- looks like I have an axle seal issue, and looks like it's been there for a while.

In reading about the repair I also realized my truck must've been converted to 5-lug. I'm curious how it was done (whole new rear end or 5-lug axles). I need to see if I can find some numbers on the rear end to see what's involved in the repair for real. I'm not sure I want to tackle it. I do want to overhaul the rear brakes but now I'm wondering if I put the money into discs instead... one thing leads to another.
