Well finally I think I have found the source of the knocking I done the spray test so I spray one suspension part at a time and brought it for a spin each time and tried to replate the noise finally after a few different parts I got it down to the control arm is making the noise because when I sprayed it with wd40 let it soak in for about ten minutes on the 3 corners of it brought it for a spin to replate the noise it's stopped so I'm convinced now that needs to be replaced to stop the noise but I think Toyota will only replace the left side and not both side because there's only 21.000k on the clock like the other parts they replaced on left side I did the drop links and bushes and pads in my local garage.so control arm lets see what Toyota say 3 months trying to find that knocking馃槨 Finally I think馃檹

So the part everyone is talking about looks like this (random picture from google)
https://ahparts.com/buy-used/2015-Toyota-Corolla-Front-driver-LOWER-CONTROL-ARM-48069-02300-4806902300/118389-1

There seems to be 2 rubber connections.
The vertical one goes to the shock and strut I think??
and the horizontal one is a pivot point to the front subframe.

Was it the spraying of WD40 on the horizontal one that stopped the noise??
Any signs of cracking or splitting of the rubber in those bushings??

It kind of looks like the big bolt squeezing it all together should be stopping the steel tube inside the rubber bushing from rotating, so all the rotation should be taken up by the rubber. If they let you look at the take off part, it would be nice to know if the rubber has sheared away from the steel tube - or the rubber is loose insidethe pressed steel A arm. That could be the cause of the noise.

Will this Liquid Wrench Penetrating Oil/Lubricant work as well?

Also, hearing people saying sway bar end links, as well as centre ones...which one is correct? Or both? I don't want to mess it up, lol.

This is what I use. A good balance between not being too thick and able to get into where the lubrication is needed.


You don't lube the end links, the bushing are what hold the bar to the car frame under the car. Crank your wheel all the way to the side and you will see them under the car just behind the engine.

I've been having some kind of squeak or clunk noise at the front side of my 2014 Corolla for several years. It happens randomly but seems to be getting worse. It started at maybe 20k miles. Now I have 60k. It seems to be worse when it's colder and drier and happens when I'm at slow speed turning and braking makes it more obvious with bumpy road or up/down driveway while turning. I've taken to the dealer years ago complaining this problem and they just said can't replicate or it's normal for cold weather only to delay fixing so it's out of warranty. Now I've taken to at least 2 mechanics to take a look. I was first told I had very rusty brake rotors so I replaced both front rotors and pads. While braking is much better but the noise didn't change a bit. Other than that mechanics can't find anything obviously wrong in the suspension. I then later did some research found many people talking about sway bar bushings and I did find a Toyota TSB for 2014~2018 Avalon and Camry squeak over bumpy road to just change the sway bar bushings. So lately I asked a mechanic to change the sway bar bushings but guess what. Nothing changed. I'm very frustrated with this problem.

Alright guys, ready to really be p***ed off? I have the answer for you and it will only cost you 10$ to fix (assuming you have tools). I made a video

Fantastic video!!!!!

I forgot to update this post - I took my car to the dealer for an oil change and mentioned the bushing noises. I had my dash-cam on "silent" mode and I actually got footage of the test drive..the guy was taking a few turns pretty hard but luckily it made the bushing noise VERY apparent.

They called me to tell me it'd be ~$700 to replace both lower control arms and perform a front-end alignment. It was then that I told them I have a 125k warranty on the car - they called the Toyota financial company and got the repair approved immediately.

They did say that the bushing were cracked and had signs of wear, but I'm wondering if lubing them up with brake lube would have quieted them down. Was that just a bottle of normal lube that you put on the back side of the pads?

I'm so glad you found a way to resolve this without actually having to replace the LCA's. My car is only at 100k now and this issue had been going on since about 60-70k, so I'm expecting to see it again in the future once I'm out of warranty!

Thank you a ton!!!! I have a 2017 Toyota Corolla le eco. Got it with 7 miles and everything was perfect. Once I hit about 11k miles is where this sound started to develop. Now at 17k. Every time I drove my car I would hear this noise at least 5 or 6 times. Once I looked up possible symptoms I thought it was the sway bar bushings. Once I sprayed those with silicone wd-40 and the noise was still there. I felt I was shit out of luck until I saw your video. I sprayed that spot with the same silicone wd-40 and NO MORE SOUND!!! Once it wears off I'll apply actual grease to it. THANK YOU!

It's amazing the difference that five minutes and a $15 bottle of brake lube made. My Corolla was loud going over bumps and now the creaking is gone!

Thanks Kaden_423!

2015 Corolla LE with 90 000 km started to make 'creaking noises' while going over small bumps in the road, no braking involved鈥 using an old tube of Permatex brake lube, I greased up the pancake bushings on left and right LCA's and the noise is completely gone鈥︹︹...quick, cheap and easy fix...

Just chiming in with another success story after greasing the rear rubber bushings on the LCA. Also want to note that you don't necessarily need to jack the car up to get the grease in there - I was able to turn my tires all the one to the opposite of the car (to get at the right side bushing, turn wheels all the way to the left) and reach in with some grease on my finger.

It'll be interesting to see how long this lasts, but I'm optimistic.

I鈥檓 going to have to do the same thing. Can anyone recommend an appropriate grease I can get for a Canadian Tire or Parts Source type place?

Weird symptom, but it's exactly as it sounds. It only happens while actively braking and going over speed bumps, or the curve in my driveway, or into a large dip in a parking lot. The front will make a groaning sound which sounds like it could be coming from the bushings. I am considering lifting the car on jacks and then loosening the sway bar and lubricating the sway bar bushings, and / or the end links.

I have a 125k extended warranty, but I'm hesitant to take it to Toyota with this problem because if they don't find anything, or if they find something but it's not covered under this warranty (ie: normal wear-and-tear) then they would charge me the $120 diagnostic fee, or apply that amount to the repair bill. My guess is that with 80k miles they would consider some noises from the sway bars "normal".

Anyone else have this happen to them?
I have a 2014 Toyota Corolla CE. I have had the exact same noise for over a year. I have had the car to Toyota 6 times. First they removed my mud flaps charging $50. Than they greased everything, said it was my hub caps, replaced my sway bar bushings, and nothing worked. A couple of times they said that they couldn't hear it. The last time they said it was my rotors and breaks that the rotors had surface rust. I had my friend take the breaks off, cleaned them all up and the noise is still there. No one can tell me what is causing the noise.

Interesting. A nice cheap fix for those having this issue. I've not noticed it on my 2009 Corolla S Turbo or 2017 Corolla iM. I wonder if it has anything to do with me installing 3-point chassis brace and helps stiffen the chassis of the car.




I also have Ultra Racing side chassis braces and a rear 2-point.
