Since I noticed one side was much harder to turn, I think one of the TBs is at a much higher rate than the other. This coupled with the soft shock setting.
Any ideas on checking tension between the two TBs? Maybe an old style torque wrench with a spring loaded pointer?

Well, I don't think you would adjust to have them the same, in theory. One front wheel might carry more sprung weight than the other. Of course, if there is a huge imbalance then it would be all screwed up any way since you would have different spring rates over the life of the TBs. Which brings you to another possibility. TBs soften over time and can do a differing rates, so the rate on one might be different than the rate on another.
There is a z-height setting that is suggested from GM which you could prolly search here and find out to figure out.
