Recently purchased an 04 Tundra Limited with 217k one owner. Having carrier bearing issues. Purchaced the first one from Oriellys and it was bad within 120 miles. Purchaced one from Toyota and had the same results. With it being non serviceable i ordered a complete driveshaft and installed it over the weekend. Its been 3 days or 120 miles and its thumping again. The truck is not lifted and the rear transmission mount is good. I am also installing it correctly with the single hole down. What am i not seeing?
