My wife has an 2000 Xterra. She had the brakes done at about 35000 miles. The bill was about $600 which I though was uuuummmmm-somewhat high!!. One of the things they did was repack the front bearings. It needed new front pads again so I just replaced them for about $80. Rotors are nice and smooth and straight so I didn' turn them. But I'm wondering about repacking the bearings. On my other vehicles which are not 4x4, I don't repack them very often but I don't know much about the fronts on this car. How often should they be repacked? Unless there is something special about them I would think they don't have to be regreased every 40 thousand miles. Do they?

Thanks
