Re: Willub's 04 STi: DSS carbon fiber drive shaft OTW!
You really have to crank the volume up to hear how bad the bearings are I guess. It is far past slightly stiff :lol: I can feel each needle bearing grinding in the caps, hence the sound. Yes, the louder occasional knock is me hitting the joint on the shaft. You really have to feel it to get an idea of how bad it is. I will make a better video with some twisting action tomorrowSo in your video, I really did not see that the u-joint is bad as you moved it in its normal motion. Appeared to be slightly stiff, but that is not going to contribute to rear diff operating temperature. Apply a twisting force if you get the time to redo the video. It seemed to me that you were hitting it against the driveshaft. (for your background - I spent 3 years evaluating warranty driveshaft/differential return parts for a major manufacturer)
