hey guys. my name is eddie and im very new to the z, and have one that to me is a diamond in the rough so im slowly rebuilding it. so im in the process of rebuilding my gearbox and my driveshaft is not in the best conditions! guess 20+ years of driving would do that. my question is: what is the opinion would it be best to have it serviced or to replace it with a new one piece unit???
The best thing to do is to replace it with a single piece driveshaft. This will eliminate the center support bearing and also give you the option to service the U-joints. The factory driveshaft's U-joints are not replacable and the a new Nissan unit is more than double the price of an aftermarket one. Most of our driveshafts range from about $250 to $350 depending on the model that you need.
