HUB CAP

This is an aluminum die-cast hub cap for oil-bath wheel ends on heavy-duty trucks. It has a 6-hole mounting pattern with a 4.5-inch bolt circle, a side fill plug for easy oil servicing, and a transparent window that lets you check the oil level without removing the cap. A vented fill plug helps relieve internal pressure from normal heat buildup. It comes with a gasket and is typically replaced when the cap is cracked, leaking, or the window is damaged, to prevent oil loss and potential wheel bearing failure.
