To fix this you have to drop the oil and the sump. If yours has a pto you will have to remove it before you can drop the sump. Undo the nyloc nut on the pto front drive flange and remove the flange. Then undo the front half and remove it. Undo the rear half and it should pull out and leave the drive gear hanging on the chain- Then you can drop the sump and get to the gears. Remove the rear driveshaft and handbrake assembly including the backing plate. Then you can remove the locking tab holding the intermediate shaft bolt. Remove the bolt (normal rh thread) it will be tight and with 1 hand hold the intermediate gears while you pull the bolt out and then you can lower the gears. When you reassemble the intermediate shaft you have to check the bearing preload before you fit it (in a vice) This is done with the small thick shim on the front end of the intermediate shaft - they come in various thicknesses) With a bit of luck you old one may be correct. Make sure you replace all o rings/ seals and torgue the intermediate shaft bolt to 125 ft/lb when you fit it. It would be wise to remove the centre diff while you are at it and check for wear especially the thrust washers and if you intend giving it some hard use I would fit a 1 piece shaft assembly (much stronger than the 2 shafts). Also make sure you loctite all the bolts holding the 2 halves of the centre diff casing together and the ones holding low gear on the casing.Have you got all the part numbers you need. Also you should be able to find all the info in the safety bulletin that AFM sent you. And a good idea while you have it all out is cut the pto chain and remove a link and buy a chain joiner link (its 1/2 inch roller chain) That way you dont have to disassemble the pto if you have to remove the sump again.
