Drove my wife's Xterra the other day and noticed a droning, grinding noise coming from the front end. I asked the wife how long it had been making that noise? Her: What noise? I got the front wheels in the air and found the passenger side bearings were shot. Called Advance to order the wheel hub and they had a 170 and a 250 dollar hub. The tech recommended the 250 hub. I told him I would get back with him. Google search and I had one ordered for $59 with free shipping. I made an "appointment" with the wife to block out about 4 hours to work on her vehicle. I had the old one off in quickly. The only problem I ran into was I could not get the ABS connector apart. I disconnected it from the old hub and reused the old one. The race the hub fit in was pretty rusted so I cleaned it up and put some bearing grease on it to facilitate reinstalling the new hub. It went back together easily. I was ready to put the wheel back on and sat back to look it over and that's when I saw the dust shield laying on the ground. It took me 2 seconds to decide the shield was not needed. I was not taking the brakes and hub back off for the piece of sheet metal. I put the wheel on and went on a test drive. No grinding noise and no ABS light. When I got home the wife was ready to go. didn't even shut the vehicle off. She asked if it was fixed, Me: Yes. She hopped in and took off.
