Most Indy's round here wanted to charge $180 with me bringing them the parts. I normally would have never even asked, but like I said it was winter and I didn't have the time or want to work in the cold. Is that a bad price? No, not at all. It just sucks when you know how easy it is to do. The two write ups on AW are good. I remember I found another one in the archives that describes the axle removal method in detail. I will look for it later when I get back from watching basketball.
Iodit...I am about 99% sure you just have to replace the boot. This is a far to common problem, and the symptoms/fixes are like clockwork. Only thing you might need to buy is that triple square bit. I found mine at PepBoys for $3.99.
This is pretty much what you need to do. Remove axle bolt in center of wheel. Remove wheel. You will see this...
A heat shield sits over the CV boot held on by the bolts that go where the yellow circles are. Remove them and the shield. Then you remove the 6 triple square bolts you see in red. When they are removed, push the axle towards the front of the car and it comes right out. Then just follow the DIY's from AW. Reinstall the same way you took it out. Its butta!
BD and Wofman are right though.....this can be messy, so wear crappy pants/shirt/gloves.
