When moving the joint on one axis, the shaft end wants to "settle" into one position, not falling
to the downward position. Maybe "notchy" is better? Don't know how to describe any other way.
Do have the "roughness" when accelerating from stop at low speed. It smooths out once above
30mph(?). It's fine above 30.
It might be I'm expecting it to be silky smooth at all speeds. When first considering a Rocket, I test
drove a new one at the dealership for a couple miles. I was in love with the Rocket after that.
However, I was surprised to notice a little roughness on pulling away from stop. Again, I was expecting super
smooth. After experiencing that on a new one, I ignored the "roughness" on mine to being the "nature of the beast".
As you'd expect, with 27K miles, the roughness is more exaggerated then the new one was.
After finding the "notchy" U-joint, I'm now wondering if mine has more of a problem? I might be overthinking this.
It's so subjective
