Front End Alignment

Thanks so much for such a concise explanation Doug! This is exactly what I needed! Yes my car drives straight hands off but I hear tire squeal especially in a turn. So I know Toe-In must be off. Maybe when I fix that I might detect other alignment problems don’t know. But this is a good start.

Can you point out what bushings you are referring of/to?

Tha ks Doug!
Lower control arm bushings are located on the torsion bar pivot. Upper control arm bushings where the cam bolts pass thru. Strut rod bushings at the front of the K frame where the rods attach. A good visual inspection will show if they are reallty bad. The pivot point should be centered in the bushing. The rubber shouldn't be split and hanging out. Make sure the strut rod nuts havent backed off during this check. Also look carefully between the K frame and front of the lower control arm where the pivot goes into the K frame. That area can crack. The other most common wear parts are the lower ball joints and idler arm. Pretty easy to check if you have a floor jack. Idler arm check; Jack the right front wheel off the ground by placing the jack under the control arm as close to the tire as possible. Grasp the tire and try to move it right to left. If it moves watch the idler arm. It will probably be moving up/down at the K frame location. More than 1/4" it needs replacement. Again no movement woud be ideal. With the wheel still raised get a 2x4 and a large bar, pipe, etc. Place the bar over the 2x4 and under the tire. LIft on the bottom of the tire like a tetter totter. If it clunks up and down the lower ball joint is worn. The car must be supported by the lower arm and not the frame for this check. Then check the left ball joint in the same manner.

I did my own alignment last summer after finishing a complete front end rebuild. First time I've done my own and I am happy with the results so far. I'll know more after I get more miles on it and can check tire wear. I also found that either the alignment shop that did it last didn't do it right or all the UCA bolts rotated since then because they were all straight up with fat end down.

I bought a 2-wheel kit from here: https://wheelalignmenttools.com/shop/

I made turning plates from some thin gauge steel that was a front panel off an old dishwasher and bearing grease.

There is a spec for what is known as "Toe out on Turns" Non adjustable if I remember. May have to do with frame alignment.It maybe in the factory service manual.
Just a thought. Check to see if your length of inner to outer tie rod ends are equal side to side.Measure from grease fitting to grease fitting.
Though this is possible start simple first. The most common causes for incorrect toe in turn? Loose strut rod bushings/nut Or the idler arm mount being in the incorrect location. Easily spotted by the drag link not being parallel to the ground. Easy fix. Again this would show up on a good rack.

Thanks I will rebuild the front suspension since visually it looks old. Then I can do the alignment AFTER NEW COMPONENTS ARE INSTALLED. This makes sense but wasn’t planning on doing it before some other work but looks like nows the time.

Toe-out-on turns is built into the suspension geometry, just as steering axis inclination. When you're turning, the outer wheel has to travel through a larger radius than the inner wheel.
 
Question is an overly sensitive steering or twitchy as I described it possibly due to excessive bump steering from bad toe in geometry?
