Wheel leak question
I had a slow fluid drip at the bottom of the brake drum on the inside (rear, 1976 F150 4x4). I assumed it was brake fluid, but now that I have the drum off, the cylinder looks dry. Is it the axle? Is that an easy fix?
I'll try to get some pics up.

Smell it. Does it have a hint of sulfur? If so, then it's time to pull the axles and replace the seals.
Easy is a relative term. How much wrenching experience do you have or want to learn? Do a Google search for "replace axle seal" and many return you should get. IIRC, Mustangs & Fords magazine or Mustangs Monthly has an online article.

I believe since its a 1/2 ton you will have a 9" rearend and you (will) should have to tap off and back on new bearings assemblies.....
Since you are pulling the axles, you might as well do a brake job on reassembly.
Insp the axle for a grove cut in the shaft from the seal, if so there is a kit for that instead of replacing the complete axle.

Fanboy,
Before you get up to your elbows in wrenching, take a quick peek at the diff breather. If it gets plugged, pressure build-up can push diff fluid past the seals.
Had this happen to me...seals were fine, just the breather/breather hose needed cleaning out.
