Okay this update mostly for Blaine...
Drove without passenger, all is well with regards to steering. Still going to center my front axle, and need to work towards centering the rear, but that'll be a little longer term, I'm afraid.
What I did notice is this...after having set my caster to 6* without specific regard to pinion, I now notice what feels like driveline vibe in the steering wheel, so next I need to set pinion without regard for caster. This was not noticed with passenger weight, and I can imagine that is reasonable if I am toeing the line on pinion.
I do believe that now my tires are balanced to zero, and a fresh and strong stabilizer, I'm ready to take the chance with less caster.
So I think that aside from the pinion seals I really need to get on, adjusting front pinion first, need to get at very least some adjustable uppers in the rear to dial in that pinion as well, as it's certainly off slightly due to MML, and I do have a wobble in the driveline at certain speeds and initial acceleration as well.
We'll have to see how money goes...would like to get currie lowers for the rear as well. Then take the time to work out the rear trackbar.
If I make it to that point, the only thing left will be SYE and TT. Man that would be something. Feels weird to be seeing faint light at the end of the long tunnel
