PP steering knuckles

[K4fxd]

Are these the same as the base car? I ask due to my steering binding when I swapped PP control arms into my base car.

I narrowed it down to the rear front control arm. If I use the base arm with the PP front arm everything works like it should.

OR

Is this (steering bind) a thing with the PP cars? Is this why I got laughed at when I said when the car is in a spin slide I let go of the wheel? Because with the PP arms it will continue to spin slide. With the base arms it will straighten out.

The more I search, I see with Shelby and without Shelby. Do the PP cars get the Shelby knuckles?

You have an issue not related to what knuckles you have. Did you install the correct rear mounted arms specific to a Non-GT-350 or GT350 arms? The ball joints are different and it changes your roll center.

It is the Ford Racing M3075-F Control Arm Kit.

Did you torque them at ride height? Your issue is not related to the parts used.

Yes torqued at ride height. I also switched to a bearing in the forward arm, same problem. At this point I have had them in and out and one at a time. Everything works until I install the rear arm. They are marked L and R so I did not put on the wrong side.

The tag on the left arm has FR3C-3A424-BA

One thing I did notice is it pulls into the knuckle easily. Like the shank on the ball joint is smaller in diameter than the original.

Sounds like it could just be a faulty part.

You have something else going on, what exact year and model vehicle do you have? What are the alignment specifications of your car?

The casting or forging number on mine is E816N, on the other side it has CE G85

It's a 2017 base GT with auto trans.

Alignment from memory is -2.25 camber front +6.8 caster zero toe
Rear is -1.75 camber .2 total toe

This may be the answer.

Any chance you can mike the ball joint stud at the base? Widest part.
