well i pulled the driveshaft today and the front u joint is a little notchy feeling so i dug out my spare and the front u joint was good rear was about the same feeling as the front was on the original shaft. ugg tried a junk yard and dident even buy what they had for me because both u joints were notchy. so i stuck the spare driveshaft in it anyway just because its front u joint was the good one and the shake definetly changed and is not as hard as it was before but still there. so i guess im searching for a good used driveshaft
