1994 Mercedes-Benz S320 Question: power steering pump
Bellow is a link to the engine driven power steering pump on your car http://www.rockauto.com/catalog/raframecatalog.php The pump for cars with self leveling are twice the price of vehicles without. Labor to replace either style of pump is about two and a half hours to three and a half hours. - patrick mannion
