The CURT 22244 protectors are designed to act as a small grease reservoir and a physical barrier for hubs with a 2.44-inch bore. They install by press-fit and include snap-on dust caps for added weather protection, making routine hub maintenance quicker and cleaner.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these protectors help my trailer bearings during towing?\u003c\/h3\u003e\n\n\u003cp\u003eThe protectors provide a sealed chamber that supplies grease to the bearing and blocks mud, rain and road debris from entering the hub.

Installation is a press-fit process that requires a clean, undamaged hub bore and the correct tooling to seat the protector squarely without deforming it.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eConfirm the hub bore measures 2.44 inches for proper fitment.\u003c\/li\u003e\n  \u003cli\u003eClean the hub interior and remove corrosion or sharp burrs first.\u003c\/li\u003e\n  \u003cli\u003ePress the protector evenly into the hub and top with the included dust cover.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow do I add grease and maintain the protector over time?\u003c\/h3\u003e\n\n\u003cp\u003eGrease should be added following your hub and bearing manufacturer's recommendations; the protector holds a small reservoir so periodic topping is usually sufficient. During routine inspections, remove the dust cap, check grease condition, reapply fresh bearing grease and reseat the dust cover to preserve protection.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eUse recommended wheel bearing grease and avoid overfilling the hub.\u003c\/li\u003e\n  \u003cli\u003eInspect for leaks, contamination or damaged seals during maintenance.\u003c\/li\u003e\n  \u003cli\u003eReplace protectors if the press-fit is loose or the dust cover is cracked.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat’s included and what else will I need to complete hub service?\u003c\/h3\u003e\n\n\u003cp\u003eThe package contains two CURT 22244 bearing protectors and two plastic dust covers; bearings, races, seals and other hub components are not included.
