As some of you know, I lowered my car several days ago with H&R springs. I noticed right away that the front end makes wierd noises. It sounds like something rubbery rubbing againt another rubber or metal. It happens when I go on bump and front springs compress.

I'm wondering if other people that lowered their accents with same springs notice that sound.

At first I thought it was the rubber tubing that covers the lower portion of the springs, when spring compresses that rubber gets squished by the coil above/below it. But now I'm not sure anymore.

I just checked the car's front suspension again, and everything that's connected to it, nothing loose, everything is tight and held in place.

Btw, I also notice if the car is raised, the sound disaapears

Any opinions? Is it normal on accents? Do other accent owners have similar sound? (I had H&R springs on my civic, and didnt have any such sounds)

My guess is the bushings are making the noise. Since it's lowered, the bushings are twisted past the normal limit and squeak. You can pinpoint the noise by spraying the bushings with WD 40 one at a time and testing it.

Have the same issue - also had the Ultra Racing bars installed, they have since been removed. My sound only comes from the left side. It looked like the lower control arm front bushing slipped, so I had that replaced. Still got the squeaking. went to dealer this AM, they say everything is tight, so that's good. So I suppose I'll live with the squeak.

Did you get your car aligned as well?

Let me know what happens with it! Glad to know someone else out there has the same issue!

Cheers

hey Dave, I found the problem that causes our squeaking. If you look at the shock, you'll see a boot sitting on it. Inside we have a bump stop. With my car sitting normally, the bump stop is touching fully the strut. Whenever I go over a bump, the spring compresses, and so does the bump stop. Since it's made out of rubber, it causes that rubber squishing sound.

What I want to know is the people that are lowered here, did you guys cut the bump stop to make it shorter or fully remove it? And how does the strut handle that?

You, sir, are a rock star! I just installed my short ram intake not more than 10 minutes ago - I'm eager to hear the sound!

Our cars are starting to look alike I think, with yours in black and mine in silver!

How are you liking it so far?

Take pics of the bump stop issue, so others can see - did you cut it already?

Promising news!

Congrats on the SRI...

much much much much much better with it :)

It seems the filter is different though (its now white)... I suppose they changed them. Anywho the car is much louder (more-so in 2nd gear) and definitely responds much better / quicker.

Your opinions? How is it so far?

Will take it for a spin in about an hour - I'm excited! My filter is the grey one - looks better imho

Let me know how you do with the bump stop issue!

Congrats on the SRI, definitly will be waiting to hear about that as well.

I'm actually going tomorrow to purchase two used front struts off a 2007 accent sport, and gonna test springs on them with cut bump stops. This way if I blow the shocks I still have the originals one to go back on.

Should be a big difference, one is the noise factor second is the feeling, with the bump stop seating all the way at the bottom, the shock absorber can't work, and ride is bouncy up front. With the ability for the shock absorber to actually absorb the bumps, the ride should be smoother as well as stiffer.

I'm wondering what's Hyundai's solution to this problem when their mechanics install the available eibach springs.

True to that!

I've been looking up (briefly) at poly aftermarket bump stops. Maybe getting a harder, but much shorter bump stop will still do the job? All the magazines I subscribe to have the occasional suspension article and mention bump stops.

This is encouraging since that sound was weird and I really wanted to know what it was!

Did you install the springs yourself? If not, who did the work for you?

Where are you getting the used struts?

hmm.. aftermarket bump stops isn't actually a bad idea. do you know any brand names that carry them, so i can look into it?

and yes, i did the spring install myself, so i know everything was done right, and was extremely surprised to hear that sound.

the struts i'm getting for a scrap yard. hopefully they aren't damaged.

Don't have the source handy with me, it was a UK site.

SRI was fun! Not as loud as I was thinking but yup, in second it seemed to roar a bit more. Makes me want to get an exhaust to even it out! Something that'll make it sound like a Subaru with that low rumble when it gets an exhaust - bup bup bup!

I am getting camber bolts as well, when they come in I'll see about taking the struts off to either replace with a bump stop or cut the original down - when are you expecting to get the struts? I have no clue what the stock bump stops look like...

So everything was going fine. I ended up getting only one sport strut, took it apart, cut the bump stop. Already took original strut off, compress spring, unscrew top nut, but the top hat didn't come off. I tried banging it out, used a puller which eventually bent the top hat, nothing worked. With my H&R spring stuck on the original strut, I ended up putting stock spring on the used one I bought, before you know it I had the car raised again, back on original springs, lol.

I need to get my hands on 2 new struts, specifically sport ones.

Good news however, after playing around with the used strut that I bought, it can easily withstand normal driving with the bump stop cut in half. It's much stiffer than non sport struts.

So is the bump stop basically a piece of rubber, like a cut rubber hose? Is it ribbed at all? Some bump stops are shaped so that it's easy to cut them evenly on both sides. Just wondering if it'll be worth it to get after market ones. How firm is this bumpstop? Sorry for all the questions, I just know others will find this useful.

So was your bumpstop all messed up from all the squishing? This may be a consideration - if it's been pushed past its normal limits, it might not be in great shape for me!

How hard is it to separate the bumpstop from that plastic boot?

So is your car raised up in the front like a lowrider car, or is it entirely on the stock springs again, until you get the new struts? I wonder how much those will cost (!!!)?

Thanks again for your work and updates!

Dave
