Hey everyone...Watch the video and tell me if this is a bad u-joint.
Sometimes when I move from a stop I can hear a clicking noise but it goes away at cruising speed. It doesn't happen all the time. The noise starts at 1:14 in the video. I thought it was the rear axle or even the CV joint but wasn't sure.
3:20 in the video shows the u-joint and it seems to be louder here. I've also noticed a line of grease slung up around the transmission/driveshaft tunnel. You can pause the video at 3:23 and see the grease on the tunnel. There was also a little bit of grease on at least two bearing cup seals. I checked the u-joint for play and there was none. Zero. Zip. Before all of this noise, I started having quite a bit of vibration under the car. I readjusted the length of the CV joint from 3-5/8" to 3-1/2" and the vibration went away, well mostly. I still get a tiny bit only around 2100rpm in 3rd gear. The noise is also gone now. FWIW, the driveshaft is 11 months old. I'm still concerned that it IS the u-joint though.
