had any one had to change them how hard is it and how much and where did you get the new parts from. Thanks

If you have some skill and the right tools might take an hour each side.

 

I've done it. Took me about an hour. Would be a lot easier with a second set of hands though. Hell the hardest part I thought was manipulating the CV shaft in and out of the spindle.

 

The IWEs should be about $75 each at many online places. My dealer parts dept. will match online prices which saves me time. Ask yours if he will...

Here's a thread on replacing. Has some pics and lists tools needed.
