Clicking/Popping When Slowing Down

[merlin803]

Probably not Mach 1 specific but I am getting the attached clicking noise from the rear of the car, every time that I slow down (the brake pedal does not have to be pressed). So, I would think it is not brake related.

It does seem to slow down as the car slows down. I can't really tell which side of the rear it's coming from, it is hard to hear it unless I am slowing down right next to other cars or a wall.

I did have one of the rear tires plugged a couple of weeks ago but I honestly don't know if it could have been doing it before that visit because with the exhaust and either having the windows up or radio going, it is hard to detect.

Any ideas? Could that be related to the tire being removed and reinstalled or likely unrelated?

It is almost like a baseball card in a bike spoke kind of sound, if the card was metal...

I had this and had to replace the rear driver side wheel bearing.

the noise then went away

I have a service appointment next week and I am just hoping they fix it and don't break/damage something else.

My 22 started making a clicking/popping noise from the driver side rear a few weeks ago which progressively got louder and more aggressive as time went on. I brought the car to Ford last week and they scheduled a warranty repair for today. They said they would be replacing the driver side half shaft, hub assembly and some other items covered under the BTB warranty. I can share the full report when I pick the car up later today. I did also ask for them to take photos of what was broken for future reference if the noise ever comes back. I can share those photos too if they ended up taking them.

At first mine was pretty quite but as mentioned it started to get a lot louder and more noticeable both inside and outside the vehicle. (not represented well in video) but mine never sounded anything like that! Mine would make one or two clicks/pops everytime I came to a stop or left a stop as well as changing from R to D and vice versa. Yours however sounds a bit more severe and I think you will definitely need a new rear bearing/hub assembly. Who knows maybe you are having the same issue that my car had and it just sounds different. Either way. definitely have the dealer take a look and see what they say and what they want to replace.

(Also Grabber Blue Gang, maybe we are special)

Mine isn't actually as severe as it sounds in the video in that if I have the windows up, or even have them down and don't drive next to other parked cars or buildings closely, I can't really hear it.

Putting the car in or out of gears doesn't produce any unusual sounds, so who knows.

Okay so here were the results. They diagnosed the car with a condition of stick/slip between the hub and halfshaft assembly when accelerating or applying brakes or during the "torque reversals", this condition results in the clink/pop noise I had. They reference tech bulletin SSM 52444. There was also a similar bulletin sent for the ford lightning back in November of 22 with some more details and the repair for that vehicle (TSB 22-2395). Below is the SSM# and the paperwork I got from the service department. Car drives great now and no clicking or pinging from the rear anymore. Your issue may be different than mine considering what you mentioned but still worth bringing up. Hope you get it figured out!

Thanks for the update, glad yours got fixed!

Just to be sure to understand correctly the term "torque reversals" - does it mean the change from where one side of the drive train is pulling the other side to the reversed situation where the formerly being pulled is now pulling and the other one is pulled?

E.g. when accelerating, the engine pulls the wheels through the transmission, driveshaft and the differential. While when braking with a gear in, the wheels are pulling the engine?

To be honest I am not entirely sure as I have not heard that specific term before. But, how I understand it is that that term is used more to describe the transfer or reversal of energy when shifting between reverse and drive/forward gear only. For example when you put the car in a forward gear the rear will squat slightly due to torque/load on the rear axle, when you put the car in reverse the rear will lift slightly for the same reason which is a normal occurrence for most vehicles. I think that term excludes any kid of movement caused when braking or accelerating and is specifically a term used to refer to gear/directional change. But It's possible that what you are saying is a factor that would cause the pinging/clicking to occur when coming to and leaving a stop.

Well, today is the 3rd full day that they have had it and they called and said they couldn't reproduce the sound (even though I showed them the video when I dropped it off......).

I went in and took the guy for a ride to reproduce (no actual tech was available......). I reproduced it (it was there but on the brief drive, it wasn't super loud but the guy said he heard it and it was a metal sound).

When we get back, he went to talk to his manager and said that it really needs to be more reproduceable when the tech drives it and he wanted me to drive it some and come back if it gets worse.

Sigh....it's exhausting these days to get any kind of service.

Bonus, even though they didn't remove any wheels, I thought to check my glove box when I got home and yep they took the wheel lock key out and forgot to put it back. I have to drive back out there 30 minutes on Saturday to pick it up (don't trust them to mail it...).
