Ok, I just installed a Ogle C pillar bar in my DA. But what pisses me off is my hatch area actually squeaks more now than it ever did before. It would barely squeak at all and now if I'm not on a smooth road its loud as ****. Any ideas why my hatch would squeak more after the C pillar bar was put on??? Ive heard if anything it should take away what squeaking you have.

I was thinking it might just be making noise where its mounted but when I grab it and shake it I cant get it to squeak at all. I used all the stock washers and stuff. Only change I made was out of the 2 washers that are supposed to go behind the seatbelt bracket, I put one in front of the C pillar bar and the other washer behing the seatbelt bracket. I couldnt get it to go one any other way though.

maybe because it's putting stress on the body of the car where it used to flex right there a little bit. with the bar there it's making the body more rigid. i may be wrong but that's what came to mind.

Anybody else have any ideas?? That might be it but I dont know and I would like to get some more input.

Try wrapping electrical tape around the latch-piece on the hatch. Mine would rattle and squeak when I had the subs bumpin', and that took care of it. Details are under Teg-tips on g2ic.com

Already did that long before the bar went in. And there wasnt really any rattles until I installed this bar, than boom all sorts of rattles.

The answer was posted right above this post.

If you put frame stiffening devices on the frame, the movable parts are gonna move.

Also, remove those gay bars unless its a track car. No point in having no cargo/back seat room so you can be JDM Street Racer boy.

An analogy: You have three *****. Roll them in a line from side to side all together and there's very little conflict. Hold the outer two ***** still and bounce the third in the middle. Well, its gonna bounce.

Thats the worst analogy i've ever seen.

And also the worst reasoning for using these bars.

Some people want to get the maximum enjoyment from driving their car, every time they drive it; These people may also not use the boot space (like myself, and if I ever do, the bars can come out in 5 seconds).

The C-Pillar bar hardly restricts backseat space....

shoot, i'm putting a c-pillar bar in AND the bar that runs behind the front seats along the floor. rattles and squeaking is awesome!

pick up a freaking honda-tuning. do those gutted cars look like JDM street racer boys?

i rest my case

two things:
1) these cheap bars are usually not that strong and not well-designed, from an engineering standpoint. they do flex, actually a surprising amount.
2) when you reinforce an axis that the car used to flex around, the car will find a new axis/axes to flex around and new points will have flex. hence you will hear the squeaking.

#2 is 95% likely the reason you hear noises now. your car is plenty sturdy and you have nothing to worry about. if you were worried you should have had a roll cage installed instead of a little aluminum bar.

what about the people that use decent bars like i do? the ones that are non adjustable don't flex much at all.

hehe yes they do. now, the steel ones don't flex nearly as much as the aluminum ones. mostly this is because [mild] steel has a modulus of elasticity of like 200GPa where aluminum is about 75GPa. adjustability has nothing to do with it; it only has to do with whether or not you can set the preload on that axis, just like setting the preload of the springs in a nice coilover set. everything is a spring in this world, including the steel chassis. it's just a very stiff one, and the spring action is in many different directions/axes. so yes, if you have steel bars then yay for you, you're ahead of the game. that's why even a 4-pt roll cage &gt; strut bars any day. it's all steel.

So did anybody catch the fact that I was using a Ogle C pillar bar?? This is not a adjustable piece of aluminum crap. It non adjustable, all steel. By far its the beffiest C pillar bar I have ever seen.

So it sounds like the squeaking is pretty normal then, I just thought maybe how I mounted it or something was leading to the squeaking.

I actually can feel the difference this bar made, opposed to my frunt upper strut bar which I didnt feel a difference. Not huge, but definitely felt when pushing the car.

Or maybe I'm just a dumb JDM street racer boy.

you'll have to excuse his sarcastic remarks everyone...it seems apok has a regularly scheduled person that pisses in his cornflakes every morning......

after i installed the EM Racing c pillar bar on my dc2, i also heard more noises. I only hear it when i'm going up or down driveways, taking a corner real hard, or when some one is sitting in the back (not recommended). I dont mind the noises because I can actually hear it "working" when the body is under stress. lol

Thats exactly when I first noticed it, was when I first backed out of my driveway. I thought to myself, damn thats loud.

95lstegman

yeah my rear bar is loud. but really if you're contemplating a C-pillar bar you really should thinka bout having a friend with a welder go in there and weld you a 4-pt thing like the EM Racing setup only out of steel and non-adjustable. it wouldn't be that expensive and triangulation would be MILES ahead of just a rear tower and a C-pillar bar. one day, when i have nothing better to do with my time . . .

Im a Metal Fabricator by trade, its great to hear a response from someone who has a clue about the geometry of a chassis. You hit the problem on the dot.

u hear it from ur driveway is because ur car is at a weird angle...u'll hear ur springs too...the c-bar will help a little not too much..n it looks tite....

hehe i'm a mechanical engineering student. it's my [future] job. glad to know a pro agrees with me. i wish i could get you to fab up some things for me. ah, if i only had access to a machine shop again . . .
