Front End Noise Mystery

[Raven9]

Mine has also done this from day one. I always figured it was wheel rub on something and the dealer could never find it either. I think I will revisit this armed with this info, thanks guys.

Wide front tires and only at full lock means large stress on the steering rack/shaft/couplers.
Good luck on repair.
I have picked up a slight knock backing out of my garage because it requires full lock due to our excellent turning radius (sarcasm ).
Subscribing.
BTW my ‘14 with big 2” primary headers does it also. We isolated it to the steering shaft but it’s only full lock so I’m living with it.

I finally got around to taking my car back to the dealership. They wanted to send it to the body shop to look for bad welds but I insisted they replace the steering shafts first. Happy to report replacing the steering shafts fixed the issue. Feels good to finally have it done.

Can you be more specific on the steering shafts? Are we talking about the steering column or the steering rack? Sorry, I am just not sure what you are referring to.

Upper and lower steering shaft and yolk assembly. Earlier in the thread someone posted actual part numbers they used but it was for a GT350 so I'm not sure if they are the same for GT500's. My SA took care of all that.

Damn. I thought I was the only Iconic black stripe in DFW. Howdy Twin. Glad you got it sorted out. The only mystery noise I have is the Track Exhaust around 1500-2k RPMs vibrates some plastic panel on the rear passenger side.

Hey JR, yeah man gimme the wave if you ever see me. I've only seen like 2 other GT500's on the road besides mine. Stay warm today!

Mine is being worked on for this as well as we speak. There seems to be a service bulletin out for this and the vibration of the back deck (if this is what you are speaking of) wsith the car in sport mofde and the exhaust in track mode. It seems there is a module mounted on the deck which is the cause.

As for this post, they have replaced my steering shafts upper and lower 5 times, the sound now is like rocks or bones being crushed when hard locking the wheel to the left, have to ask if they replaced the yolk assembly along with the shafts.

***EDIT 1.4.23***

Spoke with my Service Mgr, yep Yolk assembly also replaced 5 times. I give up as long as its not dangerous crush away.

Place thin foam around the perimeter of the trunk light assembly after you pop it out. This is a known issue.

Thanks. I'll Look into it.

Im sure we are all interested to here if you determine the culprit of this phenomenon.

Id be looking at the rearend myself. Yet, many pple had great ideas on how to troubleshoot the steer system for its possibilities in this. So there is no shortage of good ideas as to where one could search.
Perhaps someone outside the vehicle, about 5ft away from the rear quarter panel/rear axle location,
[standing bk so nobody gets run over]
might see something on the inside tire/wheel motion,
(inside = relative to direction ur frt whls are turned at full lock).

Full lock & in reverse, was 1 way to get a Detroit locker to "pop" bk when they were popular. Torsten's are much smoother than a Detroit Locker by design & application.

I could get my '19 Bullitt to 'pop' (or what felt like one anyway) the Torsten diff on 1 particular banked turn, @ a pretty high throttle load, as I was coming out of the turn past the midpoint. The rear of the car felt like it was gonna move outward on me for a dplit second, but didn't. I could never really get the rear diff to replicate this "qwik jerk" phenomenon on hardly any other corner in my travels. Yet that 1 turn could replicate it every time.

I also have to consider if nannys are/were applying brake loads for stability control in that spot, which may have then produced this feeling that went thru the vehicle . A very qwik moment of possible instability. Very qwik & not concerning, once you were used to it.

That car is gone now & I haven't been able to get our GT500 to do what the Bullitt did thru that turn.

We await any results you may find out on this issue. Regards,

Hey Guys. After months of struggle with Ford, I went to the dealership with this forum and the same issue. First they said it was something else. Finally they changed 3 out of the 4 parts listed in a previous comment ( everything except the lower shaft) plus 1 not in that list (Yoke assembly or steering column shaft coupling). Finally, happy to report, it solved the issue.

Listing the parts they replaced on my 2021 Mustang GT.

-FR3Z 3E751 C (Upper shaft)
-W714878 S450 (Yoke Assembly Bolt)
-W707137 S441 (Upper shaft nut)
-FR3Z 3N725 (Yoke Assembly or steering column shaft coupling)

Hope this helps someone else with the same annoying issue. If it does, please post it so other people reading this have more proof for when they go to the dealership.

glad to hear yours got fixed. This is basically what they did to mine last year.

With a different car comes a different mystery. My original 500 had the aforementioned noise that other people have gotten fixed with the steering parts.

My newer 500 now is making a squeaking noise when I steer left or right in a turn (not full deflection). But only after driving for about 10 minutes or so and warming the car up. Back to the dealer for me I guess.

My issue never resolved, but after determining there was no safety issue, I gave up on it, I barely am going to be driving the car hard locked steering to the left. And after hearing all 3 years have this issue was another reason I gave up on it.
