Here is the state of Missouri inspection handbook:

Under "Steering Mechanisms" (document page 26):
Quote:
Reject vehicle if:
* Wheel bearing looseness allows relative movement between drum and backing plate (disc and splash shield) more than one-eighth inch (1/8") measured at the outer circumference of the tire for vehicles ten thousand pounds (10,000 lbs.) Gross Vehicle Weight Rating (GVWR) or less or one-quarter inch (1/4") for vehicles more than ten thousand pounds (10,000 lbs.) GVWR. A wheel bearing falls apart when a wheel is removed to inspect a brake or if the bearing is broken
* Front wheel movement is in excess of one-fourth inch (1/4") for wheels sixteen inches (16") or less, three-eighths inch (3/8") for wheels over sixteen inches (16") to and including eighteen inches (18") and one-half inch (1/2") for wheels over eighteen inches (18"). (An idler arm or king pin must meet this criteria before being rejected.)
* Excessive vertical (up and down) or lateral (side) movement is evident in any of the steering linkage sockets, tapered studs are loose in their mounting holes, any movable joints are locked, any adjusting sleeves are loose, or any joints are not secured with cotter pins or other devices
* A control arm or radius arm is badly bent or broken, or if a pivot shaft or a pivot shaft mounting or any control arm, radius arm, pivot shaft bushing is badly worn or missing
* Stabilizer bar(s), links, connections are badly worn, missing, loose or broken
I suppose that one could argue that
rear stabilizer bar bushings and links would not be included in a "steering mechanism" checklist...
If the links and bar bushings were that bad, I'm surprised you weren't able to hear or feel it in the vehicle.
