99 tahoe diff fluid leaking

[chd1287]

I pulled off my drum today to tighten the rear brakes, and there is differential fluid leaking into the drum. Its just a little now, but I assume its only gonna get worse. Anyone know what I'll need to replace?

Axel seal to start with.
Also check axel bearing and axel where bearing runs.

since the axles need be removed to do this,,,,,, replacing the wheel bearings , and a close inspection of the axle surface in the bearing area is needed..

having a good bearing condition is needed with the drum brakes....
