I am rebuilding a riding lawn mower transaxle that has sleeve bearings and am having trouble getting answers as to which lubricant I should use. Some have suggested Bentonite grease, John Deere Corn Head grease or any Multipurpose EP Grease NLGI#0. Even the dealer gives conflicting information. I understand the corn head grease in polyurea based and Bentonite is clay based. Is one of these better than the others for this application?
