More excitement good noise or bad?? rear end

[Kim K Kaiser]

Well, after being sure or, pretty sure no head gasket problem,, i took her for a ride,, i had notice the other day when i was doing some short rides to get up to temp, and felt like the brakes were tight,, i could nt roll off a stop light, not a free roll,  it felt as if brake was lightly touched.  anyway, decided to day to check rear brakes as i had just re done them back  in dec.  so off with the wheels and they seemed quite difficult to turn,,they aren't as free wheeling as the front wheels,, just took effort. so, i took off the drum, checked the brake stuff, it seemed like drums tuff to get off and lots of dust.  but while i was turning,, i heard this (see video)  now I'm no einsten, but can imagine this metal on metal sound being real good. AND a touch of stuff coming out of the next section of the wheel assembly where the 4 bolts are.. 

i then checked the help section, and if those are the four or five options i have , minor leak at ends near wheel,  i may need to replace the seal.. would that be correct?  or  is there something else i should do before getting into this..   also, is this in my wheelhouse of skills..

once again, thanks for any thoughts regarding this new thing,

It sounds like a bolt head is rubbing on something.  Check the fluid level to the differential.  The area in question should be bone dry, but very minor seepage has been left for years without any bad effects. As long as the shoes don't get wet.

Ok.  I just replaced the gear oil back in december, maybe it needs to be checkex again after usage.  Everyhing around the gear box appears dry. Shoes not wet,  just lot of dust, has a sweetish smell, just some dribble down the bottom.

Dnt think that clinking is a concerning issue at this point?  Just reset brakes and carry on?
