You would need to disconnect the bolts at the rear differential to drive shaft and then see if the vehicle will push or jack up the rear end (wheels off the ground) and with the driveshaft disconnected turn the rear wheels e/brake off front wheels blocked) if the turn the differential is not siezed, change the oil anyway make sure the level was ok, remove the rear cover and inspect hte diff if you are convinced the problem is in the diff. Autozone have some popular workshop manuals for free on line once you register (for free) on their website http://bit.ly/autozone_repair_info. 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
