What's causing the clunking noise after installing lowering springs on my 2019 Mustang GT??

I track down what's causing a clunking noise on my 2019 Mustang after installing BMR lowering springs

[@madlovegaming8333]

What’s funny is it only happens intermittently. It’ll do perfectly fine and then randomly decide to click/clunk only on the passenger side too

[@raymondromero5451]

Damn me to anything figured out

[@nitro300]

This video helped out a lot. I did the vice grips and towel on my coilovers and it fixed my clunking issue.

[@RegularGuyGarage]

Glad it helped!!

[@brentbrowning2041]

I just lowered my 2012 mustang gt on eibach sport lines with SR struts and shocks and mine also started making this clunking sound. Thanks for the video man it helped out a lot

[@fherzhodakid]

that was the problem? i did the same on mine and i been having a hard time with this clunki noice

[@bigd9848]

Nice to see a video from you ✊💎

[@MrEricmitchell]

Thank you very much! i was so frustrated by the clunk i had. I got in there many times re- setting the preload and checking all the nuts for tightness but the clunk persisted. tried this tip and now rides and sounds silky smooth. so relieved. Thanks again man. you saved my sanity lol.

[@cotyreed3259]

What tip??

[@mattoquendo39]

I just figured this out earlier today after putting on my front lowering springs. Backed the car out the garage to turn it around and starting hearing a clunking sound from the front. I looked again at 21mm nut and noticed there was a gap between the nut and top of the strut plate. I tightened them down and was good to go after that 👍🏼

[@RegularGuyGarage]

Glad you got it fixed👍👍

[@iamasmurf1122]

You are not supposed to tighten that centre nut down unless you compress springs again

[@arniesandoval5106]

My 2019 s550 makes the clunking noise too.. a couple of weeks after installing pedders suspension... Thanks for video... gonna check it out

[@RegularGuyGarage]

Hope it helps

[@ftamiguelful]

What is your wheel and tire set up? How is the ride with the lowering springs? Thanks for the good videos.

[@thomasrouh2258]

I've had this issue on pre-assembled struts several times......if you're going to spend the money on lowering an s550 do your homework first......The very best option is not to cut corners on the install......I can't stress enough how important camber plates and billet shock mounts are. Even if it's not a drastic drop you're changing the geometry of an engineered suspension. And to make the torque specs correct on that strut a lot easier buy yourself a strut socket for the price of the vice grips. Then seriously correct the ball joint roll center with Steeda control arms.....If you do it right the first time it will cost you less in parts and labor down the road.....

[@brentbrowning2041]

I also did not realize that you aren’t supposed to use vice grips on the shiny parts of the strut... I used them on bare strut without a rag and never messed them up. Only thing that went wrong was the strut nut came loose

[@Stangy850]

Thanks so much for this video been having the same problem

[@RegularGuyGarage]

Hope it helped!

[@sunyoungg5634]

Great video thanks - what I use instead of the towel with the vice grips, is an old leather belt.

[@RecaroSR3]

For those of u who ever read this and after tightening but are still facing the sound , change the Bush stopper to a shorter one at the top mount or cut it , I changed mine to a shorter one and the sound went away , the suspension has limited travel hence causing the springs to not compress fully or not able to decompress due to the limited stroke , hope this helps someone out , it took me a few days and changing multiple parts to figure this out myself with the mechanic

[@goldenkickz3308]

How much you think of cutting off the bush stopper

[@iiAzT3Cii]

Wow this is it. My tein springs even came with a paper explaining how much to cut off the stopper. 🤦‍♂️ ill try it tomorrow

[@isicks2k128]

Tf is a bush stopper?

[@DREW11114]

did the noise happen when it was cold out? cause im getting a clunk noise when hitting a hard bump when its 60 or below

[@lobbyrobby]

So your thinking that nut loosened up? Any benefit to putting blue loc tight on it?

[@jedicookies1046]

Have the same issue on my 22 Camaro after putting Eibach prokit springs. Really hope this helps!

[@boostwayne]

Did you have the stock struts or are they aftermarket?

[@jesterm1460]

Just installed some adjustable sway bar links on my 2016 gt. I adjusted the sway bar links as small as I could since my car is lowered on eibachs and now I'm getting some clunking in the front and can't figure out wat it is😞

[@jeremyhigh3186]

Try replacing the strut mounts, they will cause a clunking noise, especially when making a tight turn. If clunk is over bumps, try up grading sway bar end links.

[@bryansantos31]

I put the tein lowerings springs on lancer gts 2016, when being parked and turning the wheel to get out from the parking, there was at terrible clunking, some people recommended putting on lithium grease every month and it fixed it temporarily, are you sure it's the strut mounts? which ones should I get?

[@Salty5hoe]

I literally just installed the steeda progressive springs on my 2021 run through it 3 times both sides both fronts are tight nothing loose , and both factory struts are clunking . Does that mean the factory struts are not compatible with the new springs ?

[@cheetoshotfries2289]

So you telling me i should check my shocks? They are adjustable stock shocks i think

[@EconomyElk]

What torque wrench do you use?

[@garrettpittman7374]

My same side was loose but I caught it before the first test drive....I kinda banged it just a little w an electric impact bc it was spinning and for whatever reason it dont when you bump it w an elect impact lol

[@kevin5slo396]

will this also happen to me on my s197 5.0 ? i hear clunking in the rear ! i am lowered

[@renegarcia7591]

Honestly it May not even be the lowering springs bro as crazy as this might sound it could actually just be the rear seat latch trust me I’ve had that same problem and I was totally sure it was my suspension but turns out it was just the rear seat latch many owners on the forums have also stated this

[@kingcobra7565]

torque w the car on the ground! Hooahsemperfi brother!

[@VogelStang]

I just installed lowering springs and have a clunking too. Funny that other videos i watched from reputable companies did not mention torquing the strut bolt. I will try this.

[@user-mb5kx2wi7r]

did it work?

[@VogelStang]

@@user-mb5kx2wi7r sure did! Strut nut was way below toque spec. After I did this the clunking was gone 👍

[@christianoliva4978]

Did it sound Like a squeaky bounce?

[@MrDalon37]

Question sir: I’m about to lower my s550, so do I torque the strut nut before mounting it or after it’s mounted? I’ve watched CJ pony parts videos they don’t show this? Thank you in advance 🙏🏽

[@garrettpittman7374]

I ran mine down w the spring compressors still compressed on springs then rechecked when I got the front totally done as like a once over last step...low and behold one was loose just like his and I caught it before I drove anywhere...no noises everything feels like a factory job

[@VidTubeWatch]

How loud was the clunking sound before you tightened the upper strut nut? Your video speaks directly to me because "I just installed new rear coil overs" on my '05 RSX Type S yesterday. LOL. I am going to check the upper strut nut tomorrow. As soon as I drove the car after the install I heard a very noticeable clunking (thump thump thump) sound from the passenger side rear. It sounds like a big rock being slammed around inside a 55 gallon drum. It is easy to hear outside the car as well as my neighbor was on his driveway when I took off for the test drive. I immediately turned around and jacked the car up in my driveway and took the wheel off. The bottom nut was tight. I made sure the collars on the coilover were tight and checked the two nuts on top of the strut mount. I now have seen where several people had issue with the actual upper strut nut. I'll take it out tomorrow and see. I think also being in the rear that the spring may be hitting against something. At any rate was yours a pretty loud clunk? Mine happened as soon as I drove forward. Didn't matter if I turned or hit a bump. It was in a rhythm with my speed.

[@RegularGuyGarage]

Some coil overs will make noise, but my clunk happened anytime I would hit a bump. The type of noise you’re describing with yours is pretty accurate though to what I was having. Especially since it’s just the one side in the rear. Hope you get it figured out

[@VidTubeWatch]

@@RegularGuyGarage Thank you for your reply. I took off the passenger rear coil over today, and the preload was not set properly. I should of checked before installing it. You live and you learn. Function and Forms website says it is set for preload and ready for easy install. I also went around and tightened all the sway bar bolts on both sides of the car and anything else that I hadn't touched previously. Took it for a drive around the block and no more clunk.

[@onireno]

🤔 This might be my problem. I installed lowering springs, and after two weeks it developed a clunk. Perhaps, the stiffer suspension causes the bolts to back up a bit. I will check mine again.

[@christianoliva4978]

What’s your wheel and tire setup? Car looks sweet!

[@AStanton1966]

Did you happen to notice the check tire pressure light lite on the dash?

[@thecoach1683]

Thanks for the video. I have a clunking noise on low speed turns after lowering on springs. I tried this and the top nut was not up to torque, but sadly the sound persists after torqueing. All other bolts are tight. My next suspicion is strut mount bearings are done. If you or anyone else has ideas let me know.

[@mrpep1976]

Did you ever find your problem ?

[@thecoach1683]

@@mrpep1976 unfortunately not, but the sound ihas is not as noticeable any more. I get a wobble taking right hand turns still though.

[@fherzhodakid]

@@thecoach1683 i have the same problem i chamge the lower arm thinking that may be the problem, but still, and only in like small bumps imma try to check that

[@thecoach1683]

@@fherzhodakid good luck let me know, my clunking went away on it's own, so springs must have had to settle or something, but when i accelerate when turning i hear a wobble. could be the axles, not sure...

[@Head0fTheHerd]

Well this explains a lot 😅

[@phajejlaib429]

I just low my car when i turn lil make nosin damm might check tomorrow

[@burrofilemon1823]

I did the trany bushing and shifter bushing and its a big change on the shifting more Precise Recommend it

[@RegularGuyGarage]

Burro Filemon I was just talking to my buddy about doing a shifter next 👍👍

[@burrofilemon1823]

Regular Guy Garage Best thing you could do in my opinion The shift will bee more precise will not fill rough in between 1st to 2nd second third . And i did a oil separate her as well And I subscribe to your channel because I wanted a Camaro ss 1le but decided to get the mustang and then you got the mustang best decision ever 👍

[@Pinkielover]

why Would you mess with stock In the first place you void all the warranties

[@xorrcisedo3585]

Mine ended up being the sway bar end links! Solid video tho.

[@INTHEFIELD777]

Do you mean they were just not tightened enough? I’m having the same issue. And I believe it to the sway bar links. Mine have zero play in the bushing/joint. I’m hearing from my friend that they are supposed to have some. I dunno. I’m not a mechanic lol

[@nate2x._]

My 2017 camaro ss makes the same noise after I installed My lowering springs

[@Capital_Shorts]

Nate 2x did you fix it?

[@eugenegutierrez5106]

I had my install with Mexicans can’t even speak English. My RR it’s making a noise once in while. Any suggestions? I’ve noticed whenever we lower our vehicle the aesthetic is there but comfort it’s never the same. Think planning to go back to normal height.

[@jimcornettelaugh7120]

Go back to normal height you hick👍🏻

[@cheetoshotfries2289]

I just lowered my ride and i get the clunk in low low speed and bumps but at fast speed its smooth...

[@arko_0.0]

Same

[@5.0noah12]

More than likely a rear suspension, if it doesn’t clunk under load.

[@justinfarris7045]

I put lowering springs in my tl and when I take sharp turns at low speed it makes a clunking/grinding noise from usually front left and scares the shit out of me and feels like it drops a half in too

[@bryansantos31]

Did you fix it?

[@jaayd5oh688]

What are the consequences on not resolving the clunking noise?

[@RegularGuyGarage]

I would say breaking suspension parts if it gets bad enough

[@alexhernandez4114]

I broke my strut mount. The inside part was pretty much grinder out. Also, I believe the noise comes from the spring coming in contact with the frame, as it did for mine.

[@Starhopper6]

What was the torque specifications again?

[@RegularGuyGarage]

76ft lbs

[@ronaldluther324]

Your wheels are sweet . Gt350 style looks great on your S550. ☠☠☠

[@christianbarrera1093]

THE REASON IT CLICKS IS BECAUSE OF THE SWAYBAR LINKS
