NatesGr8 Posted June 1, 2006 Share Posted June 1, 2006 Will do. I have gone through most of the suspension a couple of times now, but I haven't checked that. I'm pretty frustrated, and plan on taking the Cusco FSB out this weekend. I want to eliminate variables, and put the stock back in to see if the problem is still there. I can't handle the clunking anymore, and it's embarrassing to have people in the car with it making all those bad noises. the clunk will go away with the stock fsb. the problem is loose bushings, well its not that the bushings are loose, its b/c like 1/4 " of the bushing rests on the curved part of the sway bar so it makes the rest loose. i will be reinstalling mine this summer with narrower bushings to see if that works. right now i'm running just the rear and its silent.

AKLGT Posted June 1, 2006 Share Posted June 1, 2006 does it hurt to just install the rear sways then? will the front really make that much of a difference. i don't want to deal with any annoying clunking sounds as I drive my car 85% of the time for work. but i'm autocrossing this season and need better suspension. Wiggle wiggle wiggle wiggle wiggle yeah!!! Link to comment Share on other sites More sharing options...
JuxtaGT Posted June 1, 2006 Share Posted June 1, 2006 Thus far, I have no issues with the RSB. Nate, that is a good point about the bushings resting on the bend in the bar, I noticed that on install. I wonder if the bushings are borked now, or if I could try and recess them with the magic dremal tool? It can't be this hard to make a freakin sway bar work right. Maybe i'll sell Cusco and try the Cobb now. At least they will still both be blue! Link to comment Share on other sites More sharing options...

This seems to be a problem not everyone has. Installing the rear alone won't hurt anything. I feel the front sway does make a big differnance on turn in. It also helps control front body roll, keeping the tire flat on contact patch to improve corner traction. I've noticed very little outer edge wear on the tires since the FSB went in. I really like the way the car handles with both in. BUT THE CLUNKING SUCKS ARSE! Link to comment Share on other sites More sharing options...
NatesGr8 Posted June 1, 2006 Share Posted June 1, 2006 i was thinking about dremeling the outer edges of both bushings but haven't had the time to do it. maybe i'll give it a shot when things at work slow down a bit. and are the cobb bars finally out?

NatesGr8 Posted June 1, 2006 Share Posted June 1, 2006 just checked it out on cobb's website, they're bars are out, and look sick. I like the reinforcment parts for the rear. maybe i'll switch over to cobb. anyone want some cusco swaybars. front and rear???? Link to comment Share on other sites More sharing options...
SW7RT Posted June 2, 2006 Share Posted June 2, 2006 I'll be getting the JDM rsb soon. Is there anyone here that has the JDM bar and clunking noises? Link to comment Share on other sites More sharing options...
NatesGr8 Posted June 2, 2006 Share Posted June 2, 2006 Jdm rear does NOT clunk, nor does the cusco rear bar, or any rear bar that i know of. To my knowledge only cusco front sway bar has clunking issues. Link to comment Share on other sites More sharing options...
SW7RT Posted June 2, 2006 Share Posted June 2, 2006 heard the same about the whiteline. my stock rsb clunks on my rear control arm during hard acceleration. (lowered iON springs) Thanks for the reply. I've iON springs like Han'sGT but I haven't noticed any clunking under hard acceleration and was wandering if I got the larger AVO or JDM bar should I just get the adjustable endlinks too?

JuxtaGT Posted June 4, 2006 Share Posted June 4, 2006 Okay Gang, just so we aren't out there repeating ourselves, here is what I tried this afternoon. This is going on the premise that the Cusco FSB is too narrow, and "prys" open the bushing creating slop. So, I trimmed the bushings. While I was at it, I also put hose clamps to prevent the bar from sliding. This did NOT fix the problem. I think my endlinks are toast. Next stop, ordering some rod ends to build my own adjustable front links. Link to comment Share on other sites More sharing options...
CobaltForge Posted June 11, 2006 Share Posted June 11, 2006 Juxta, After your experience, would you recommend the Cobb FSB vs. the Cusco? Also, you mention bushings, what type do you think would work better? Link to comment Share on other sites More sharing options...
LittleBlueGT Posted June 12, 2006 Share Posted June 12, 2006 Juxta, After your experience, would you recommend the Cobb FSB vs. the Cusco? Also, you mention bushings, what type do you think would work better? I have no problems with the COBB FSB at all. I do have a clearance issue with my COBB RSB (like the clearance problems others have had with other RSBs) but that is solveable with longer end-links. Anybody know where I can get longer RSB end-links? Full tune of 68HTA, KSTech 73 MAF, Racer X FMIC and ID1000s................by the DataLog Mafia!!!

JuxtaGT Posted June 13, 2006 Share Posted June 13, 2006 Juxta, After your experience, would you recommend the Cobb FSB vs. the Cusco? Also, you mention bushings, what type do you think would work better? Given the choice right now to start again, I'd get the Cobb set I think. If the new endlinks stops the clunk, and it is for sure that broken endlink bearings are my noise..... Then it may be a matter of time before Cobb FSB owners have the same problem. I do think the Cobb bars are a little softer, which would have been okay by me. The grease fittings are a welcome touch, so is the RSB reinforcement bracket, which I'll be ordering shortly. I just think the Cobb is a better thought-out and engineered set. Had I known I was only a month or two away, I would have waited. I will say, the Cusco set feels very balanced, and I have zero issues with how the car handles. Only things on the road that has ever kept up on the mountain twisties was a miata clearly set up for auto-x/track, and other subarus.... Link to comment Share on other sites More sharing options...
jholder Posted July 11, 2006 Share Posted July 11, 2006 All, I installed my Cobb rsb last weekend. Overall very impressed. Recently however I have noticed a definite "clunk" that was not there before. It seems to only occur when I am on the "goind down" side of a large (~5 feet wide) speed bump. Basically going straight over the bump, and coming down (5-10 mph), the rear seems to clunk as I bottom out (not literally, buit when the suspension reaches the lowest point of its travel) Anyone had this type of trouble? I haven't had a chance to get under the car and look again (i first noticed last night), so I suppose something could have come loose. I'm not sure however. --james Link to comment Share on other sites More sharing options...
LittleBlueGT Posted July 11, 2006 Share Posted July 11, 2006 The COBB bars are likely a little bit stiffer then the CUSCOs. As far as the rear clunking, check out this thread.

Thanks, I knew they were close, and I was fairly sure COBB's were a bit stiffer. I don't think it is noticeable though. The light weight aspect of COBB's bars and their rear stiffener is what makes it a winner. Full tune of 68HTA, KSTech 73 MAF, Racer X FMIC and ID1000s................by the DataLog Mafia!!!

CobaltForge Posted September 25, 2006 Share Posted September 25, 2006 So I installed the Cobb Front Sway bar this past weekend and now I'm hearing the "clunk" that everyone is experiencing. I thought that people weren't having this issue with the Cobb? So it seems like the culprit may be the bushings? Has anyone tried switching out their bushings? I bought my front sway used and it didn't seem to have much wear and tear on the bushings. Could it be the endlinks then? Link to comment Share on other sites More sharing options...
mickeyd2005 Posted September 25, 2006 Share Posted September 25, 2006 Just my $0.02. My Cusco FSB only clunked when my front endlink was loose. I tightened it and it went away. Another local LGT forum member had the same clunking and it was a loose endlink. I used grease on the bushings (standard Valvoline grease for suspension components). I don't know if I was supposed to do that or not, but I did. Link to comment Share on other sites More sharing options...
CobaltForge Posted September 25, 2006 Share Posted September 25, 2006 ^^^ That's one of the first things I tried today. Tightend the ish out of it, but still hear it. Juxta mentioned in one of his earlier posts that he tried this, but that it still didn't solve his issue. Link to comment Share on other sites More sharing options...
mickeyd2005 Posted September 25, 2006 Share Posted September 25, 2006 I thought Juxta mentioned that it "helped." I think it has something to do with the fact that the Cusco and Cobb sway bars are narrower than the stock sway bars. This means that the endlinks are more angled than stock. Since there is a ball on each end of the endlink, the endlink is a 2 force member. The load vector is in the same orientation as the endlink. A load on the endlink will mean that there is a side to side load applied to the swaybar. I believe the sound you are hearing is the swaybar moving to one side and then popping back to its original position. This can be caused by many things. Maybe loose endlinks or too much play in the endlinks ball or maybe the hole in the swaybar is so big that the flat surface on the endlink pushed through partially in the hole? I don't have the stock endlinks on the car anymore. I switched over to the MSI endlinks. I added enough washers to bring the total width back to stock, but the endlinks are still not vertical.

CobaltForge Posted September 26, 2006 Share Posted September 26, 2006 Thanks for the info MickeyD! I'll try re-tightening the endlinks. I think I may have to go with different endlinks eventually. Link to comment Share on other sites More sharing options...
algol Posted October 17, 2006 Share Posted October 17, 2006 I just installed cobb front and rear sway bars, and, although the car handles much much better, I am experiencing certain creaking sounds when pulling into my driveway or driving over uneven roads etc. I wouldn't categorize it as a clunk. It's really just creaking or squeaking or something along those lines. Everything is greased up very well and nothing appears to be lose. The noise does not occur when turning sharply or quickly but just when going over bumps, train tracks, etc. Most of the time I have the music on and don't hear the creaking anyway... I just hope nothing is wrong. Seems like no real solution has been found yet...? Link to comment Share on other sites More sharing options...
LEGGTLTD Posted November 7, 2006 Share Posted November 7, 2006 I have the Cobb RSB. I installed Avo endlinks about 3 weeks ago. Now all of a sudden the 'clunking' noise started only from the left side. I checked it and it is definitely not loose. I noticed a thread for Cobb's support brackes. Does anyone know if these brackets will alleviate the clunking? They are about $170.00. So they are a little pricey. But it may be worth it to me if it solves the problem Is there another 'Fix'?
