I purchased this 2005 trailblazer LS V6 with high miles and as expected, it has some noises and vibrations. A friend told me that the front boot of the driveshaft needs replacement. I also noticed that the rear universal join looks rusty and dry. So a Googled for a diagram of this driveshaft without much luck, so I am still not sure how many universal joins I need, but I cannot locate this front driveshaft boot. Everyone is advertizing the entire driveshaft, while I only want to purchase the front boot. I found topics describing people who actually purchased a rebuilt kit, but the links they posted were so long ago that they no longer work. Can anyone provide me some good info please on how to proceed?
