^ according to the diagram it looks to me like i need both of the bearings, but one has grease fitting, and one doesn't. Do i just need one of the two or both.
It has my brain scrabbled. sorry. :confused2:

The inside and outside bearings/bushings are different so you need one of each. I myself hate the new bearings that they use. Don't fit tight, hard to get a grease gun end to fit correctly, and since the inside bearings isn't tight most of the time(can turn inside the rim without moving the wheel) the outside bearing never gets greased.

Got the bushings in the mail, oops let me rephrase that..
Got the thin wall PVC pipe in the mail today.
Those things seem kind of dinky for that mower. I figured they would have done like JD and upgrade to ball bearings.
