Clicking coming from wheel assembly when in four wheel drive. I just replaced the wheel studs on my 2000 Nissan xterra. When I took it for it's first test drive I noticed a buzzing noise coming from the wheel I worked on, the noise goes away when I take a turn In either direction. When I put the car in four wheel drive a clicking noise seemed to come from the wheel assembly. About two clicks per rotation of the wheel. Any help on what you think might be causing this would be greatly appreciated. Thanks

YOU NEED TO CHECK THE HUBS FOR PROPER OPERATION LIFT THE FRONT END TRY TO SPIN THE TIRE U WILL KNOW BY THE AMOUNT OF FORCE IT TAKES TO ROTATE THE TIRE

Have someone check the u joint in the cv shaft for that wheel.. they make a clicking noise when 4wd is engaged.. it puts a load on the shaft.. .. often cheaper to just replace the cv shaft

None of those answers are correct, as they obviously have never worked on an Xterra. As an Xterra owner myself, and automotive TECHNICIAN... You need to remove the rotor/hub assembly. To do this, you will need a 6mm allen head to take out the 6 bolts holding your hub onto the assembly. Once this is off, you will have to remove a snap ring from around the CV axle input splines. Once that is off you will be able to remove the bearing assembly inside. Take a 14mm socket, and remove the 6 bolts holding the hub onto the rotor. You will also need to remove the caliper from the rotor, and hang it with a piece of wire up and out of the way, being sure not to let it hang free or drop. With the caliper off, and all the bolts out you should be able to remove the rotor/hub assembly from the CV splines. Then you can seperate the hub from the rotor, which will probably be rusted on (Cushion the face of the rotor on a towel, and being sure not to hit the rotor, hit the flat surface of the hub with a hammer which will break loose the rust). Tap the top of the old studs out thru the back of the hub...then tap the back of the new studs in. They need to be able not to slide in and out of the bore, but don't necessarily have to be flush with the hub. Once you get everything back together and tighten the lugs on, it will pull the studs the rest of the way thru the hub and seat them properly.

Hopefully this helps...There is no need to take it to a machine shop or do ANY kind of pressing in or out. There is NO giant hub nut and cotter pin to remove.

Check your fuses,they are not cig. lighters.If you put a radar detector in the cig. lighter fuse will blow.

problem cv joints and or "U" joints and or worn slip joints in drive lines
no make model year listed so impossible to know exactly

Hit up www.nicoclub.com/FSM/xterra/2000/
That's the factory service manual which will provide detailed information.
There's an inner and outer bearing on each side

if you go down right beside the intake manifold you will be able to get to it

battery is dead, check the battery and charging system.

i would start by checking the wheel barrings on the side of clicking located just behind the brake assembly

1 remove the tire ( on side of clicking )
2 remove the brake assembly ( remembering how it all goes back together )
3 remove the rotor

you should see the wheel pins that hold on your tire give that a turn and have a listen for
grinding, clicking, squeeking, or any other abnormal noises

you can at the same time check your balljoints located on the upper and lower part of the control arm
look for busted/broken boots and or some play by moving your control arm up and down and side to side

Check the U Joints. My wifes xterra had 80K miles on it, same symptoms. Was a bad from u joint. Nissan mechanics and 1 tire shop could not figure it out.
