Pull the tire off the planatery assembly. Remove steering cylinder pin and bolt in tie rod. If they won't take grease, they'll come out hard. Cut wires running through the 8 hex head bolts that hold the castings onto the axle assembly(4 top and bottom). We use a cherry picker to support the planatery while we're doing this, chainhoist and a-frame will work. The top and bottom castings are square, with grease zerks in the middle. There are two holes, drilled and tapped for bolts. Remove the plastic plugs(if they're still there), find the right size bolts for the holes, and use them to force the castings off. Pull planatery assembly away from the axle. If the the drive yoke stays in the axle, remove it, along with the drive shaft. There will be a shim, top and bottom, that the planatery casting rides on, the bottom one will fall off when the assembly is pulled away. There is a hole in the shim that fits over a peg to keep the shim from turning. It's found on the planatery casting. We have a slidehammer to remove the oil seal. Drill a hole in the seal, screw in the slidehammer, and pound away. Usually two holes will take one out. Check the bushing in the axle housing when the seal is out. If the yoke has too much play, the new seal won't last very long. Those bushings run $30 apiece from Case. If there's a groove in the yoke, we use a speedi sleeve to get a smooth fit with the new seal. Re-install everything and torque the 8 bolts to 230 ft. lbs. If the 2470 and 2670 take the same parts, I can get you numbers from my list.
