The part you describe on other cars is called the drive shaft or axle support bearing. There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online

the best thing I can recommend for a do it yourself guy is get the steering knuckle off the van and take it to your auto machine shop. They should be able to press the old bearing out and the new one in for less than 100 bucks
