Hi everyone, i am experiencing a weird clunking noise in the front end of my car. I would appreciate any help or guidance towards troubleshooting this issue but please read the ENTIRE post before commenting.

So heres how it started:
I was coming home on about a 45 minute drive and i heard a single clunk noise when going over a bump slowly. I didnt think anything of it because im on coilovers and well, they make noise sometimes. I then was driving highway speeds for a while and there were no noises. As i got back into town it was almost like every bump i hit, even small ones you can barely feel, would make a clunking noise in the RIGHT FRONT of the vehicle.The left side was making no noises.

I pulled over on the side of the road and rocked the car back and forth...No noise. I pressed up and down on the right front...No noise. So i just drove home (still making clunking noises) and figured i would try to figure it out today.

This morning i tried to figure it out and here is a list of what ive done so far:
-Jacked it up (there was a strange creaking sound when i lifted the right front end)
-Wiggled the tire back and forth...No noises
-Checked coilover spring...it was tight
-Checked top mounting bolts on coilover...All tight
-Checked End link...Tight
-Released the jack (made another creaking noise on the way down)
-Rocked the car and pressed up and down on front end...No noises
-Drove it around the block...Still making clunking sounds!

Im just puzzled as to what it could be. Thanks in advance for any help

No i checked its not that. Its more of a hard hitting sound. Almost as if the entire coilover is loose but its not.

I had the same problem. And I know you said you checked it, but mine ended up being the top nut for the front strut. It felt tight when quickly checked but after really giving it a good snug, I felt it start to twist and now my problem is gone.

If it's not that, then another thing I read was maybe the side engine mount? I didn't look into it much because I needed up finding my problem but maybe that's something to look into.

Alright, i checked over that again and it was tight. Couldnt even budge it with the hex key in and i looked closley and the nut is as far tight as it can get because it is stopped by the camber plate at a certain point.

Also i checked the motor mount not it.

here is a video of what is sounds like in the car. Its a lot more noticeable in person of course

and here is a noise i noticed when applying pressure to the coilover and compressing it. Doesnt seem like the same noise but they could be related...Maybe

How did that end up? Were you able to find the problem and fix it?

I am getting the same problem with my Mazda 3 2014. That clunky noise in the same place. It's driving me crazy. I took it to the dealer service 2 weeks ago... they changed the suspenssion bases and the problem remained...

I have a similar noise, I discover that it's coming from the cv axle, the part that connects with the transmission feels a little loose, I think the seal it's getting bad :(

I will out $20 on your endlink. Take a torque gun and go at it in reverse. Then forward, the speed at which it goes should negate the need for the allen key and it will be nice and snug. Just did that to mine over the weekend.
Your second sound is just your strut compressing, can't do much about it.

I was checking my front suspension today as I'm also getting a constant clunking from the front. My front sway links were tight but seemed to be very easy to rotate around. Is this a sign of bad front end links? Everything else looks snug..Thanks..

Mine was doing it. Turns out my the bolt for the CV joint was loose. At least that's what I understood from what the tech was telling me. Noise is gone now, though. I'm not lowered or anything.

clunking in the front end

Had the same problem with my mazda 3 after replacing both struts, all motor mounts, sway bar end-links i decided i would change the lower control arm ball joints even though i couldn't get and popping noises out of them when moving them around. Problem was fixed. and the squeaking noises u are hearing is the rubber bushings in the control arm were it connects to the frame. hope this helps.

My 2014 Mazda3 iTouring (5-door) has made a similar sound from the day I drove it home brand new!
Took it to the dealer twice and they could not hear the noise, they said.

Just like with other drivers, it comes from the front end when I go over speed bumps at a slow speed. It's also louder when the tire pressure is lower (30-32 psi as opposed to 36 psi recommended).
I discovered this when tire pressure had dropped without my knowing and the pressure sensor came on.

There is a separate noise that I hear when the steering wheel is turned all the way and when I'm turning slowly typically in a parking lot.

Hope to take it back to the dealer since it's under warranty (I have only 11,500 miles on the car still).

I have this same noise on my 2010 mz3. Its ont he driver side and I hear it most while hitting a bump while turning (e.g a parking lot entrance) and when its cold out that same area creaks when turning the wheel in a stationary position. I looked around when I serviced my brakes but I didn't see a single thing wrong. The ball joint and all other rubbers and knuckles are good, suspension components are good, drivetrain components are good. Im starting to think its the fender shifting as the body flexes

Usually that noise comes from the front endlinks. Tightening that fixes that problem for most people.

This usually arises after suspension component install (usually DIY) since many people don't or can't retighten the endlinks properly

I have stock suspension. Are they known to come loose?

Went to transmission seminar recently. I've been in this particular auto business many years as re-builder,then heard if you raise a vehicle on not a drive on hoist you will strain the mounting on struts ,shocks especially upper rubber mounting,damage done replace the mounting probable only way is replacement of shock or strut .you can try to tight the nut that was always tight to no avail,your fighting against a preset factory sleeve.

My Mazda 3 2014 just started doing this. Did you ever pinpoint the problem?
