For those of you interested I've attached the TSB, that has the part numbers.
Thanks!!. Looks like those shields are mounted to small tabs that are not on the original hold down bracket of the stock arms. They are still workable for me, by welding tabs on the edges to hold them down with the main two attachment bolts. Wonder if ford can order just the shields, will try to find out today.

EDIT: Ordered them today from local dealer, $9.33 each, will be in tomorrow.

I had the fortunate timing to deal with this on my 2012. I would highly recommend upgrading them. www.whiteline.com.au offers a vast amount of suspension products for the mustang platform. Most of us are driving our cars hard anyways if we are not on the track.

I too have a clunk when going over a bump. She only has 6,500 miles on her. . Took the car to the dealer, showed them the TSB, ( thanks guys,), and they confirmed the problem, and ordered the part. Thank you all one again.

Just to follow up on my #108 post above, the dealer confirmed the left side LCA needed changing,but they changed both sides with the heat shields and parts. No more clunking.


I found out about the TSB from this forums - Tks much!

Question

I had mine replaced for the grunt sound at about 25k miles. Now I'm just over 36k miles and I'm getting a popping sound, not the same as before, but I hear it still could be related to this TSB.

If it turns out to be the same issue, what are the chances of getting them replaced under warranty? These are probably less than 6 months old.

I just looked at the control arm and there is no shield installed. There are brackets and bolt holes, but no shield. The invoice says the part used was CR3Z-3078-D and CR3Z-3079-D, which I'm pretty sure comes with the shield.

This is BS.

You can buy those shields for like $20 or less I think. If you already have the tabs you could put them on next time you change your oil. I have the same arms as you I think (would have to look at my invoice) but that was installed a LONG time ago. Like 2 years ago but I think the part number is the same. I haven't had any noises out of them but I'm not 100% sure I don't have the shields on theere. Don't know what I'm looking for when I'm under the car. You have a picture by chance?

I have a 2014 V6 mustang, I the day I bought it I had a problem with the LCA, I brought it in and they replaced it. Within 2 weeks I had the same problem again, not wanting to go back to the dealership and deal with all that I waited a few months. I now have about 7k miles on the car and brought it back in a few weeks ago for the LCA problem, they claimed they did not hear it and did not fix the problem. Also my belt squeaks when I start the engine cold for a good minute, they said they put belt dressing on it, but it still squeaks. I see the LCA is a common problem...

Something that worries me more than all of that is when I come to a stop at a light sometimes or when I put it in park the engine really seems to drop in its idle (almost feels like its going to die) at times.. Has anyone experienced this?? The air-conditioning compressor really seems to create A lot of stress on the engine, so I usually don't use it. When I use the windows it also seems to stress the engine a lot... Just wondering if any of this is normal or anyone else has run into these issues.

-Thanks

PS. I saw a Ford representative respond to some comments and take interest in some concerns, sure would be great if they wanted to help me out. Seems like I've had nothing but problems in my NEW car.

Good chance. You should have a warranty on the part which isn't involved with your car's warranty.

The dealer also installed my second set of LCAs without the shields too, in the past. I went back and they were added.

I went back and they stared at me blankly when I asked if I could have the shields installed. They said they don't have them, and I just gave up trying to force them into anything. They supposedly checked the LCAs out and didn't see any problems. I'm out of warranty now and done with the dealership. If my control arms go out again I will gladly buy aftermarket and my car will never see the inside of a dealership again.

As far as my current noise, it doesn't seem to be the LCAs. I checked for myself and I don't see any play in any of the parts. I forgot to check the shock mount, but I will soon.

In my experience, I'm not the least bit surprised, and wouldn't expect any better service for warranty work from a dealer. My alignment is still slightly off from when they replaced the LCAs. They did align it, and it's apparently still in spec, but it pulls to the left and didn't before. Warranties are nice since there's no out of pocket cost, but to have anything done is like pulling teeth. It barely worth the headache and I'm kind of glad to be past 36k.

My 2013 had the same suspension noise issue. The noise was only in cold weather. The front LCA's were replaced in September 2013 (15000 miles) Had the same issue in November 2014 (30000 miles) the LCA's were replaced again. Three months later I had the same noise. The LCA's were replaced again. This is the fourth set of LCA's on my car with just under 36000 miles on it

All parts replaced by Ford have at least a 12 month warranty on them. There is also a mileage warranty but I think it's 12k unless otherwise stated.

If you have an '11 or up GT, just throw some BMR LCAs in, grease 'em up real good with 100% synthetic grease, and replace the steering gear with the Boss 302R steering gear and call it a day. Grease the bushings every 6 months and you will have a far superior car with no popping noises. For the 2010 and below, I am not sure since they use the fluid power steering. You might be able to get away with just replacing the control arms on those cars.

And I don't think you really need to change the steering gears on the '13 and '14 cars when switching to polyurethane LCAs. Can anyone confirm? I know for a fact I HAD to on my '11 because the '11s don't have the option to change the steering performance like the newer cars.

Also- get rid of the stock ceramic brake pads in the front and replace them with some sort of high-end, low-dust brake pad. I contributed 35% of my front end noise issues to the stock brake pads (groaning when stopping and ceramic squeeking sounds when holding the brakes at different pressures when at a stop).
