The seals for your Sportsman are NLA and probably have been for years but the good news is they can be replaced with current SKF seals. The part number for the SKF seal for the driveshaft is 4770 and for the propshaft seal it is 5523. The original seals had a retaining ring on them so these ones need a good sealer on them while installing to help hold them in place. Gear oil must be used to instead of grease as there is a ball bearing on the bottom of the driveshaft.
