Small leak

No, its not oil, well that too, but check out the pictures. Drove the beast to work today and get home and noticed some brake fluid on the tire with a very very small trickle from one of the bolts. Only saw it drip once. Then it seemed to stop. Also a little fluid on the front of the back left wheel. Leaky main seal? Hasn't happened since I've owned it, hot weather maybe? What can I do to fix these two little tid-bits? New gaskets?

Cheers,
Andy

Are you sure it's brake fluid? Looks like it's leaking from around the drive flange. That's an easy fix, you can make a gasket from cereal box cardboard or just clean it and seal it up with Hylomar. Also looks like the swivel seals are leaking, that's a bit more work.

All you need on the drive flange is Hylomar, they used to use the thinest paper gasket, Cereal box cardboard would be too thick for this aplilcation but very good in emergencies in other places.
Check the axle breather is clear, that often leads to the axle becoming pressured and forcing oil out.
Check the lip of the swivel ball seal isn't full of muck - run a thin blunt screwdriver round under the lip of the seal and clear any accumulated muck out. If that doesn't work you could drain the swivel of oil and refill with one shot grease. A slightly tired seal will often hold in the grease but not EP90 oil.
Failing that it's new seal time.
First remove the wheel, then you can remove the calliper and tie it back out the way then undo the 7 bolts that hold the swivel to the axle case and pull the whole thing off without messing with the hub, stub axle etc. the drive shaft pulls out of the axle tube complete. Oh, it's quite heavy. You can stand it in the laid flat on the floor wheel undo the retaining flange that holds the seal in replace the seal and you won't even have lost the swivel grease that you put in.
Assembly is the reverse, it can be tricky to get the diff to engage with the drive shaft as you put it back in but it's easier if someone turns the other wheel very gently.
