Hardlymoving writes about do-it-yourself automobile maintenance on various makes and models.
This article, via video, will show you how I replaced both front CV axles on a '97 Infiniti I30. Since the Infiniti I30 and the Nissan Maxima have the same chassis, engine, transmission, and suspension, this procedure can be performed on the Maxima as well.
On this Infiniti I30, both the left and right axles' outer CV boots had split and slung out the bearings' lubricating grease. Over time, moisture and dirt (as well as the absence of grease) will wear away at the CV bearings and bearing cages. As the parts loosen with accelerated wear, the axle shaft will begin to wobble, resulting in wheel vibration you can feel while driving.
Split CV boots are a common cause of wheel vibration, but not the only cause. For example, although the metals used in CV axle components are very hard, riding into large potholes can damage CV bearings and cages and bend axle shafts, and this will lead to noticeable or even annoying wheel vibrations at high speed.

CV Boot Replacement
On this job on the Infiniti I30, I didn't do a boot replacement, because the rebuilt axles were on sale for under $30 and the cost of two boots per shaft would be around ... $30! If the CV boots have recently split, there's no wheel vibration, and you decide you want to replace the boots, the second video below shows you how to do it.

Replacing the Transmission Fluid Output Shaft Seal
While doing this job, you can take advantage of the axles being pulled out to replace the transmission fluid output shaft seal. This seal is seated in the transmission that the axle slides into. You can spend an extra few minutes and around $5 - $10 to replace this seal and forestall a future transmission fluid leak due to a failed seal. The video below shows you how I did that.
