Hi Art,
I’m very interested in the part about it being an “off the ground” alignment.
Camber must be a trick to measure without a vertical reference except from the floor or the frame?
Don’t think I have seen that done before with the suspension not compressed either. Especially during a brake job or not.
I have reset my toe-in while the car was on the car rack before. I made a plate to bolt onto the bottom of the car before I removed a steering rack or tie rod ends. Those bolts for the belly pan are accurately place in relation to other frame components. The plate holes are also made symmetrical.
There is the same strains on the rack ends that are on the rod ends from the hanging. So any play at those extremes is repeated as before.
Any play in any parts will hardly be an issue or hasn’t so far. Tires wear normal and it holds the road straight.
Toe is not a very sensitive adjustment when so many other angles are moving up, down and all around. I was only interested in the one exact point on each wheel to repeat back in.
The plate fits solidly onto the cross member under the engine where the belly pan goes.
The plate held a piece of EMT Pipe that I put adjusting screws in each end of.
It was then set to the insides of the cars rims up as high as I could get it for the maximum accuracy.
The plate bolted on and now always centered had the preset rod to fit it from the center of the car to the rims. I imagine, but haven’t tried it, but the setup should fit from car to car very closely.
I adjusted each tie rod end to bring the rims in to touch up again.
A make-shift gadget it might be, but I use to work shifts, to make engineered things before!
It’s surprising how similar they can be along with their fixtures and tooling.
