I agree that it's most likely a bearing failure, but not due to an accident since there are zero signs of any damage or repairs to the suspenssion or body. Also, the carfax was clean. I distinctly remember going over a deep in the road where the car almost buttomed out, and I strogly belive that the extra weight inthe trunk strained/stretched the bearing to a point that the yoke started to wear. I'll try to get all the parts this week and put her back together this weekend. I"m reaplacing all rear bushings while I"m under there. Need to get here ready for a corvette show next weekend!!

Quick question. What diff fluid should I use?
