So I just rebuilt the transfer case side of the front drive shaft. I thought that this was going to solve my vibration problem. And although it did help with the vibration it didn't seem to get rid of it. Although it does seem that I am at least headed in the correct direction as I replaced the bushings for the steering rack and that also helped a small bit. So what I am thinking now is that I need to replace my CV's. From what I have read I should only use reman'd CV's so that they are the correct length. So this brings me to my question. Does it matter from what auto parts store I get them as long as they are reman'd?
