Home Parts Services Spring Grease Pins Trailer air ride Bushings Contact Us About Us Photo Gallery Directions Spring Grease Pins can be a cause of Popping High miles and heavy loads will wear out all spring pins and bushings even if they are lubricated. They wear much faster when no grease is used. This is a good example of a lack of lubrication. A poping and rough ride can be a result of dry and rusted spring pins. When a grease pin is run with out proper lubrication it will wear into a "D" shape that will cause the truck to ride rougher, may cause a poping noise as the pin trys to rotate in the bushing and binds up. In some instances the pin can freeze completely in the bushing and the spring eye will break off from metal fatigue. Some of the newer Kenworths and Petes come from the factory with rubber spring bushings. While you do not need to grease this type of bushing the service life can be reduced from wearing and breakdown of the rubber in the bushing. After the rubber becomes unbonded from the metal of the bushings you get a very bad poping or banging in a turn. We correct this by replacing the rubber bushings with greasable hardened threaded steel bushings. The hardened threads made in the pins and bushings provides much more bearing area and wear surface for longer pin life. the only down side is you do have to lubricate them. This picture is of the same truck spring from above showing the new hardened greasable pins after installation. Print | Sitemap © John - 1&1 IONOS MyWebsite
