And the saga continues..., i thought the clunking was gone buts its not =/. im lowered, have stillen adjustable sways front and rear, spc rear chamber kit, adjustable end links, and im still experiencing the clunking sound. everything looks tight, i sprayed the rear bushings with white lithium grease, and still experience the clunk. its seems to be side to side dependent, in other words i can hear it come from the left side, and the right side, its not in the middle per say. HELP before i sell this thing!!!

ill try taking the bushings off and regreasing, seems as if this may do the trick. Where can I get NEW sway bar bushings from? Thanks for all your help man! i have the adjustable endlinks so that rules out the stockers making noise, ill just hafta check the bushings for now

 

i had a clunking noise after rear sway bar install and I finally got to fixing it this weekend. I just simply loosened the two rear most bolts (the only two you can get to when everything is put back together). I didnt go crazy loose on them.

I just loosened them enough, then retightened to the point where it required effort and then backed off about 1/2 turn of the ratchet. No more clunking and I double checked my endlinks to see if they were split or broken anywhere, they visually appeared normal.

 

nice! im actually in the garage as i type this, what should i use to regrease the bushings?

 

just finished this with what you said, definitely made a HUGE difference. Theres still a slight slight sound there but i think its due to the bumpy roads and 27 degree weather with bald tires. thanks for all your help everyone!

 

its back!!! I wanna fix this damn noise!

 

when i put the rear sway in (same for front too) I wrapped teflon tape around the bars just in the areas that the bushings would make contact with, i then also applied a good amount grease per the directions for my cobb bars.

the teflon tip is something i have seen and read about as a little grass-roots trick for low-to-no maintenance sway bar bushings.

already after almost 300miles on mixed roads and cold weather my clunking hasnt returned and I used to hear it on a daily basis on the same routes everyday before i loosed the rear nuts.

 

Maybe it's the bushing they give with the Cobb/Hotchkis rear bars, but I tried using Teflon tape, but it got mauled the second the bushing was tightened. The only resort was to bore out the poly bushing to the point that the bar freely moved when the bar was mounted to the chassis and torqued to the correct spec. Boring out the bushing made all the difference. All the clunking is gone. 100% and has been so since I did the mod about 1.5 months ago. It beats having to spend $160+ on endlinks which really aren't the true fix.

 

yea man ive bought endlinks im at my wits end, honestly contemplating parting the car and putting it back to stock if i cant fix this. I guess ill have to bore out the oem bushing, put teflon tape on it and then grease the shiet out of it.

 

anyone?

 

im in the same boat man.

 

fvcking selling this car, im sick of the problems. u do one thing and 12 others go wrong. going on my 3rd drivers window motor in less than 8 months, driver seat messed up again, clunking, rattling, if i wanted a car worse than my last one i woulda spent it on a piece of crap. i didnt think infinitis quality control was that bad considering i went from an I30 to this, and its sad that a car with 190k on it had better paint and less problems its whole life than i have in 8 months with this

 

I wouldn't exactly call these serious or "piece of crap" of problems. The seat problem can easily be fixed in 2 minutes if you follow my seat fix DIY. The window motor problem sounds like an annoyance and something tells me there is something else wrong with window system that is overworking the window motor. 3 failures in 8 months of a part that rarely fails tells me there's some other problem. As for the sway bar, I'm telling you, bore out the bushings. It will fix the problem. Period.

I don't know if you've modded cars before, but usually aftermarket parts are rarely built to OEM tolerances nor have the R&D necessary to alleviate what I consider excessive NVH and fitment. There are few parts that I've purchased that either didn't fit exactly like OEM or didn't cause some little annoying issue I had to address. It's the nature of the beast.

 

CreativeDesignZ try taking out the sway bars and drive without them and see if the clunking is still there and go from there. If it is still there then it could be the control arms and many other things. Take them off and see what happens. If the clunking goes away, i would just swap the aftermarket endlinks with 05+coupe endlinks and it should resolve the issue. The thing about adjustable endlinks is the they are very hard to adjust properly and to tell u the truth i don't know how u would do it. There is always going to be some preload on the sways and that can cause clunking from the most surprising places.... Get rid of the sways for a while and try figure things out that way.
