Need to replace the cv joint boot on a 2000 buick century (outside)

First i think you should replace the cv axle instead of trying to just replace the boot, if the grease leaked out and dirt got into the joint then the joint is bad in soon you will hear noise or joint will let go. the time it take to replace the boot and the cost of the bbot i would replace the axle, you can buy a rebuilt axle for 45.00 with the exchange of the old one. heres directions to replace the boot. remove the wheel then remove the brake caliper and bracket, tie this of to side. take brake rotor off it should slide off, you may need to tap to break it free.next is to remove the center axle nut, after that you will remove the lower balljoint nut and split lower control arm from spindle, you may need a pry bar to sperate the control arm from the spindle, pull spindle out and slide axle out of the spindle.to replace the boot cut the inner and outter boot clamps, slide boot back and look inside for a clip., some use clip inside and some outside, look at shaft going into joint, see if theres a clip to open to slide cv joint out. if theres no clip then its an internal lock clip and what you need to do is hood the shaft and bang joint off shaft, you will need some help, hold the saft or use a pry bar and slide it into the rear of the inside joint between the back of the joint and the trany and give it a tug the joint will pop out of the trany this is a lot easier to work on off the car, put it in a vise, loock the shaft in vise to keep it from moving then hold outter joint straight and hit joint with hammer a few times and it will slide off, to install tap back on to lock it back on the shaft. with joint off remove old boot and clean shaft, insall new boot with clamp first then install outter clamp, install joint and grease, put grease into joint and the rest into the boot, make sure to clean the joint before installing it, after the install place the boot on the joint and clamp both clamps, install the axle, hope this helps, good luck.
