I cant tighten those small bolts anymore IMO - brand new washers. Easy enough to torque to spec though to make sure.
As noted above, fluid level isnt changing. Need to check diff fluid level - it was filled recently and should be full.
Where I'm at right now is based on sampling the leaking fluid - after considering the comments above, I'm in agreeance it feels and looks more like diff fluid than brake fluid.
Need to do a better visual inspection and comparison of fluids.

 

OK. Diff fluid is actually a pretty thick oil and its consistency is very different from brake fluid so hopefully that will help. The coincidence of the brake work and the leak showing up is odd, but it's certainly possible. No depletion of the brake fluid reservoir would definitely rule out brake fluid as a source. There looks to be enough there that you would definitely see the level drop.

 

Its the Diff Fluid - finally pulled the fill plug and started filling and it took way too much given I just did this a month or so ago.
Ordered new seals and will hopefully have this done in the next day or so.
Being forced to WFH helps minimize my need to drive it which is good......

Hubs dont feel loose at all so not worrying about those just yet - assuming its probably just age and the new fluid since I have no idea how long the old fluid was in there.

 

Check your diff ventilation tubes while you are at it... Over pressure inside the diff will force the fluid out... but the axle seals do fail too as you know... Just to make sure you fix the right problem first.
