Front end bind

[StPro]

When you put in upper control arms were the two mounting bolts installed from factory?

[Matty]

Yes and bushings were pre-installed

[Matty]

Yes I have the pin put of the ball joints. No I am not going for that look poboy! That's what I am trying to fix.

[Matty]

it works now. first thing I noticed is a missing cotter pin in top ball joint. did you pump the ball joints full until the boots pouched out? The car does look to be sitting high in the front, is that the look you were going for or just the way it ended up?

Does it stay up if you jack it up and let it down slow/

[Matty]

I can pick the front by hand make it stay up to 29 sometimes. Other times it will fall back to 28. Then I can push it down to 27. To get to lock up at 29 to were the suspension will not move I have to drive it

Since you want it lower than it is at its lowest. I think I would cut off 1/2 a coil or do the shelby drop or both. but if your front tires are big they may rub if you go too low, so you might just do 1 thing at a time. a lot more work. looking at the video it looks like it only hangs at the highest, which I suppose may be binding the balljoints or something. the shelby drop will drop it 1/2- 3/4'' but most likely 5/8'' is what most people report. but it will improve the handling, even regular driving, because it improves the geometry of the control arms & steering rods.

Matt - In that pic you posted...I couldn't tell, are the front tires on the ground e.g. bearing weight?

Have you thought of building of a quick set of slider plates to go under the front tires to see if it is just the alignment problem? Lay a 12”square of 16Ga sheet metal on hard concrete with a large circle of grease in the center pour some BB’s in the grease the grease keeps the BB.s from rolling away. Lay a12 “square of 1/8“ sheet metal on top and slide under front tires while the car is jacked up. If the car still stays up you have a mechanical suspension issue. If it won’t stay up it is an alignment problem .

I use this setup all the time when setting up race cares before sending them home with customers.I tell them they still need an alignment but many times they tell me the alignment shop didn't touch it

Just an update. I found a chart that lists falcon spring lengths from the factory. It states all are 14.25 long. Autozone says lists the falcon as 14.8125 and the comet ad 15....could my springs be to long? Another thought was body twisting from the v8 power?

I have my old springs off my Comet at my shop. I can measure them for ya tomorrow.
Body twisting?? Anything is possible. Quick check I would do is put a reference mark on the top of each shock/spring tower. Measure the distance between the marks/towers with the car in the lower position and again in the upper position. See if the distance is the same. If it is greater when car is in the upper position then the towers are twisting.

Yes it is on the ground.

That's a great idea.
