Stemco Wheel Hub Cap

Did you know that a cracked or leaking hub cap can quietly compromise wheel-end lubrication? The Stemco Wheel Hub Cap does more than close up a hub—it keeps lubricant where it should be while shielding internal components from dust and road debris. This particular model includes a transparent window, allowing maintenance teams to check fluid levels at a glance. Once installed, it adds a level of predictability to maintenance by reducing the need for disassembly during inspections. Shop the Stemco 340-4263 now.
