That's what I will try next just to get that out of the way. Was getting late last night so it will have to wait till i get home from work today

I am up near vernon so it is a bit of a hike. But honestly if I dont resolve this I may eventually take you up on that offer. Thanks!

Haha right!? the rediculous thing is that the noise is traveling. Seriously I sound like a psychopath but my GF and I were trying to find the noise, and we would hear it in one place ... then would get down there to really take a look and reproduce the noise, and then it would happen in another place.

I can only assume because the noise stopped happening last night, and only started again after I would jack up, jack down, then turn the steering wheel.

Other side is on the ground w/ no driver side load (no one in the car/ no simulated driver weight).

My concern is that if I disconnect the links, and the noise stops that could mean a few things. That either the bar is in some way making the noise or the link is causing some tension on other components when the car's suspension is not level. I guess I will find out

Also I am not sure if it is apparant from the video's but I tried to record right near the LCA's to see if the noise was coming from there / if i could see movement, and as crazy as this sounds, it almost sounds like the noise is somewhere towards the center between the motor mount and the cat. At the moment that is the best guess isolation that I have.

 

the first thing I would do is put a wrench on any and every bolt I could lay my eyes on

I had a knocking noise that drove me nuts for a while, sounded like the RF suspension, but eventually figured out it was loose bolts on the RH side of the the brace that is bolted across the rear of the front subframe

you might try putting the front up on jackstands with both wheels off the ground and then jack up one side, it will allow you to get under the car and try to locate it better *if* it will still make the noise with the car lifted

Thanks for the reply. Will surely be spending some time under the car today hunting. Good thing is I have the workshop manual so I have all the torque specs handy.

 

So I have been thinking about this all day at work, and in my idle time been listening to the youtube vids i took. ASH said something that kinda hit home that I will have to thoroughly check when I get the car up, and that is the LCA/UCA bushings. I have said that I heard the noise coming close to the middle of the car, right behind the motor mount... our LCA vertical bolt is there. Now the car is only 2 yrs old, 12500mi on it, but because I am lowered, what are the odds that i put some extra strain on the bushing there?

I did check the torque of that bolt, and it is up to spec (100ftlb) ... but that doesn't mean that the bushing is shredded up on the inside.

The only thing that has me saying that it might not be that is there is no feedback in the steering when i am hearing the noise ... I would assume that any non-rotational movement of the CA's would change the camber/caster of the wheel right?

I will have to lift up the car and disconnect the endlinks to get some good play on the control arms, but till then I am so distracted from my work lol.

 

I think you are off base on the control arm bushings, they would only make that kind of noise if the mouting bolt wasn't tight enough and the inner metal bushing sleeve the bolt passes through was moving within it's clearance play and slapping against the bolt as the control arm moved

 

Well... i am pretty embarassed and frankly hate myself right now. So after looking at random bolts i decided to look at the torque specs of the sump guard. Low and behold i was way off the 20ftlb spec. After meeting the spec and driving the car......sound seems to be gone. I am at dinner now and will know for sure when i pull into my driveway.

Pretty ticked off at myself.

 

Look at the bright side. If that was it, you've fixed the problem. That's success and better than the alternative.

 

Your kidding Paimon....the S2 alloy Sump Guard!!??..gee I just tighten up mine until they are firm...yours must have been pretty sloppy, 7 bolts for memory.

Trying to get my head around the Guard moving enough to make that noise when jacking up, I guess it could flex that much?, ....but then I though "steering" was a thought of the noise?

Good to see it is fixed.

 

Well i just got home, and every spot the car made a noise now no longer is an issue .... i can't wrap my head around that either, must have been the flexing caused by the guard across the bolts? I really dont know... all i know is that i am excited it is fixed, and ashamed at my noobness.

 

Perhaps a little structural integrity can be added to the list in addition to protection for those who ask about running with it removed.

 

/\ Agree...it is all there for a reason, perhaps more than one, or two on this occasion...it would want to be at around $335...

 

having been there and done that I can empathize ....
