Easy easy easy.. First look to see if the ABS sensors are on the backing plate on your truck. If so remove the ABS sensors.

Remove the rear cover

Remove the 8mm bolt from the center pin in the diff.

Remove the center pin

Push the axles in and remove the C-clips from the inside end of the axles.

Remove the Axles

Remove old seals

Clean all mating surfaces really well

Carefully install new seals at the end of the axle tubes

Make sure to put a little gear oil on on the axle side of the seal.

Carefully re-install the axles. Do not let them ride on the seal or bang into the center chunk.

The rest of the assembly is the reverse of the disassembly.
