I decided to take a look at my CV's today since they were making a bit of noise. I figured they had to have plenty of grease since I just serviced them at the beginning of the season. I was very surprised to find out that they were almost dry. I am very impressed that the KAR TEK CV's held up so well being that dry. Any way I have been wanting to get some of these greasing spacers for a while but just didn't have the extra cash to do it. After I saw what I did today I went ahead and ordered them. They look like they should work well.
