After hearing an awful noise coming from the underneath of my 2004 xterra, i came across this





After looking up u joints online, I cannot find u joints online and also looking for this housing shown above. It sits pretty much in the center of the underneath that holds the drift shaft. Right now, I can freely move it in any direction and it looks like some gasket or bushing has come apart. any help would be great.

you listed no info on the model or year of your X so heres what I got for ya

BTW That is the Carrier Bearing also referred to as the Center Support Bearing. You will have to unbolt the U shaped bracket from the cross member and remove and separate that drive shaft. Take the section of the shaft with the carrier bearing on it to your local machine shop and have them press the old bearing off and press the new one on.

When I did mine the machine shop charged me $20 for the pressing and I only spent about 1 - 1.5 hrs actually working on the truck.

This is really a pretty simple job.
