I have a 89 blazer with a 6" lift. i recently got a tom woods driveshaft high angle with the cv joint a $550 shaft. within 3 months i have blown up the cv joint 3 or 4 times. i even shimmed up the rear end because i called tom woods and told them what was happening and they told me to shim it up to a certain degree. but 2 weeks later i blew it again. whats wrong here and i do not reccomend tom woods shafts because one he doesnt fix them for free when you break them more than once and ive only had it for a few months.
