Typically about 500 miles of easy driving will be enough. No towing or hot rodding during this time. Also, be sure to make short trips the first few times out (~15 miles) and allow the rear end to cool completely before continuing.

Change fluid after those 250-500 miles and you are good to go.

Good advice but keep your first 2-3 trips under a mile and let cool completely.
