01 Sportage convertible 4x2 auto
I have a 2001 Sportage convertible. I recently replaced a bad u-joint on the rear of my driveshaft. It’s a one piece shaft, so it’s a pretty much simple and straight forward process. Upon driving the car for the first time after replacement, I noticed a vibration in the shaft. I removed and completely inspected my work to insure no mistakes were made. Still had the vibration. I removed the shaft and installed another new u-joint. I still have the same vibration and the its bad enough at highway speeds that I’m afraid to drive it too fast. I’ve been a mechanic for 35 years and have never had this much trouble from a u-joint job. Any suggestions would be greatly appreciated!!
