1996 Nissan Sentra

Your CV joint will cost you $30, the boot another $15 and 3 hours to attach to the axle. In order to do that, you would have to remove the axle assembly from the car and the cleansing, removing, and re-attaching the CV joint on a work bench.

You can get the entire remanufactured axle for about $75. As you have to remove the old axle out of the way anyway, you would spend and additional $30, but you would have saved yourself 3 hours of headache and grief, and a few swear words I might add, by replacing the axle as an assembly.

Follow this one. The original question was a 98 Sentra, but it is the same for your year.
