Control arm steering knuckle

[tkswan]

2002 Lincoln LS V8 248k miles.

The OEM transmission finally quit so I had a certified transmission installed. A Ford dealership did the work. The new transmission is a beast. So much so that I think the original was a dud.

So these cars are notorious for front end noise and knocking, but recently it got worse. I replaced the bearings because I needed bearings anyway, one was howling. The noise (specifically the front left wheel) was still noisy lots of knocking.

I took it to my car guy. He actually installed new front left and right side upper and lower control arms a couple of years ago. Today he right away saw that the left control arm is loose and too damaged to be repaired. So I need a new left steering knuckle and upper control arm.

Car guy asked me if I had any work done. I told him about the transmission and he suspects that Ford did not re tighten that control arm bolt.

And my question is:

...when installing a transmission in this car, does the procedure require that the control arms or any other suspension parts, get removed or messed with?

Thank you.

Per the factory service manual, no suspension components front or rear need to be removed to remove and replace the transmission.
