A grease gun helps you lubricate grease fittings, wheel hubs, and more for suspension maintenance and repairs. Grease guns can be used on a variety of projects, including machinery and auto repair, or non-mechanical hardware and other applications, and helps you lubricate and saturate a single part without wasting grease or making a mess. If the handle on your old grease gun begins to stick, or the tool is not steadily supplying lubricant, you may need a new grease gun. At O'Reilly Auto Parts we carry several styles of grease guns, and a variety of grease types to help you complete your next project.
