Took Gramma's car out for a test drive this morning. Very smooth. No floating or tire rubbing during suspension movement when going over bumps. Actually no real wallowing or jouncing at all, like it did with the old parts. It rides very nicely now. Not even a hint of a rub at full lock in either direction any more.
Prior to the suspension rebuild, the passenger side front tire was a good 3/8" further out of the wheel well (when viewed from above) than the driver's side - due to the worn control arm bushings. Now it is in the exact location as the driver's side tire. YAY!
Once I pull the rear end out, rebuild the rear springs and replace the bushings and shocks, she should level out a bit.
The ride height is as follows:
Left Front: 28-11/16" to fender edge..................Right Front: 28-8/16" to fender edge
Left Rear: 28-13/16" to fender edge...................Right Rear 28-6/16" to fender edge
I thought it a little odd that the driver's side is taller than the passenger side. I then went and measured the 19,000 mile SD455 fender heights and found that it had the exact same stagger gap between left to right.
Here is a photo of the car with the factory 80,000 mile suspension components:
And today with the new front springs (prior to the test drive)
