Greetings all, I own a 2000 Xterra, 3.3L, 4wd, with 162,000 miles on the odometer. I have been checking the front hubs after driving some distances. The front hubs are warm to the touch but not hot enough to make me take my hand off, does not burn my hand. I jacked up front end to check to find a very small amount of wiggle, top to bottom, on the wheels. I am guessing that the bearings need to be packed and adjusted. But if need to be replaced, are the front inner and outer the same on a 4wd? Plus, if necessary to replace all where can I get the best price? Does anyone have the part numbers and whos parts do you suggest. My Xterra has not been run hard either off or on road. I have replaced and the front sway arm bushings and link ends. Thanks for the information. MTG
