| This listing is for the factory Nissan half shaft U-joints. The inner u-joints hardly ever go bad, (when factory joints are used)so only replace the joints that are defective and leave the rest alone. These are the factory U-joints and they do not have a hole in them for a zerk fitting, so they are much stronger for those of you that like to abuse your car a lot. These u-joints do require special techniques to install which is unlike any other u-joint that we've seen. We recommend having them installed by us, or by someone who has been properly trained on these procedures, it does make a difference. Otherwise use our aftermarket u-joint, they're easier to put in. See listing. Each u-joint comes with a bag of clips. These clips are unlike all the aftermarket ones because each clip is a different thickness. This helps you set the preload on the u-joints to the specific application. If you would like a less expensive u-joint we carry those as well, see listings. Last update 07/11 |
