Most likely it should have the MTD equivalent of a "00" grease.
Thanks for the advice, HCBPH.Do the end panels of the auger assembly unbolt or are they welded on (which I suspect they are). If they bolt on, unbolt them and go from the ends. If welded then you have to pull the augers along with the impeller to gain access to them.
From what little I can see, I suspect they are just some form of alignment bushing. If you know someone with metal working equipment, if feasible I'd see if you can get some bronze replacements made as they'll last a lot longer than plastic ones.
Or try the manufacturers customer service for info.If your manual lists something, that's what I'd use first. Just some thoughts.
For parts, I'd start with Sears. If you can't find them there, then I'd start online. For bushings, if they're loose or seem worn I'd replace them. If you have the thing apart and have to do it later, that means more time and seal etc again. IMO, do it once and be done with it.Thanks again, HCBPH.
Where would you suggest I get the seals from? And would you recommend bushings too?
