If you have a full-floating axle, it's pretty easy. You do have to have one specific tool though - a rear axle nut socket. Loosen axle bolts and lug nuts. Jack up rear end and remove wheel. Put a bucket under the hub to catch oil. Remove bolts and slide axle out. Remove axle nut snap-ring. Remove axle nut with axle nut socket. Pull drum off - make sure parking brake is not on - might have to use rubber mallet. Clean brakes and drum using brake cleaner that is OK to spray directly on shoes. Axle seal is in the brake drum. Knock out the old seal from the outside. Re-grease the bearings - buy new ones if you have the scratch. Tap new seal in place. Slide drum onto spindle. Torque axle nut to 50ft-lbs - back nut off no more than 1/4 turn and install snap ring. Install axle with new gasket. Torque axle nuts to 80ft-lbs. Check rear end oil level and fill if necessary. I recently did this to replace a leaky seal, took me about 2 hours or so - most of the time is taken up in cleaning the oil out of the brake assembly.
You have to remove the brakes, rotors, wheel hubs, axle shafts, diff cover, and differential carrier, seals are on the inside of the axle tubes.
very carefully
It would be recommended to replace the rear axle bearings and axles when they are worn/bad. If the bearings and axles are okay, just replace the seals.
When you see rear differential fluid on your rear brakes & assembly.
On the front axle, passengers side of carrier housing.
I have a 1951 John Deere A that is seeping oil out of the one axle out close to the wheel. Do I need to remove the the rearend and the big bull gears and get to them from the inside? Paul Lehman
Axle seals
That depends on what seals are leaking. The inner front axle seals will cost you over 6 hours of labor plus seals and fluid.So if your local labor rates are $100 an hour that will be over $600That depends on what seals are leaking.

To change the rear axle fluid you can remove the rear cover from the axle and drain it that way. If you don't want to remove the rear cover you can use a pump and a hose to drain it through the fill hole.

The K version is four wheel drive; the C version is two wheel drive (usually the rear axle).
New seals work best.
