ALL clunking noise solutions.

so what is better?

for me to get a larger front bar or rear bar?

21.5mm is about 35% stiffer than 20mm. (21.5^4/20^4)-1*100%

Cool deal...

Thanks for all the info. Certainly $200 is way too high just for bushings. If we could make inserts only, I would guess somewhere around $30-40 at most for a pair. I leave open the possiblily that a new high performance bracket may be necessary. Also, we will look into some replacement endlinks. Our Subaru models are very popular, however the stock subaru links are C-shaped plastic, and flex quite a bit. The straight links on the Mazda can be improved somewhat, but not as dramatically as on the Subaru.


Thanks

Sweet. SO what materials are you considering using? H&R makes poly bushings for some anti roll bars, and they have "teflon impregnated lining to eliminate squeaking, etc"...(quoting from the new SCC with the Red Supra on the cover. Keep us posted. These will sell best if you get them out while it's still cold.

I didn't think that going from the stock 20mm to a 21.5mm would be to much a huge difference. But enough to be noticeable. I can already sort of get a little off throttle oversteer. Not really, the back end stands up and moves out from the turn.

Cool deal all around though. Thanks for tech info.

Wait...are you implying that you did the swap already?

Just curious, why are those numbers raised to the 4th?

Just curious, why are those numbers raised to the 4th?

The torsional spring rate is proportional to the polar moment of inertia, J, which is pi*D^4/32.

No, not yet...And depending on what happens Sunday, not for a really really long time.

$200? Are you guys NUTS? They're little peices of poly/rubber???!!!

Kartboy: Assuming that they would be in the same cost range for you to make as the shifter bushings, then $25 for the rear set should work, if it's just two little bushings. Maybe a little more $ for the fronts if they're harder to do. I don't understand where they're coming up with this $200 number from...

The main thing we want is something that won't make any noise. Ever. If urethane has potential to make noise, don't bother with it. What materials do you have to work with? What are the ups/downs?

Right, right ... Kartboy, you hear Kooldino?!? Don't be charging me no freaking $200 for some tiny little pieces of rubbery thingy!!

I threw up that amount in the first place since I didn't know if we were all 100% certain all you had to do was replace the bushings with a bushing made of proper material to make the noise go away. I'm just saying I wouldn't pay more than $200 for ANY type of fix for this particular squeaking noise.... I'd rather just live with it until the day I trade it away for something else.

Mazda hasn't been able to do it right for us, so I'm not sure what's the deal with our car's noise (makes me wanna buy another Mazda in the future.... NOT!). So yeah, I'd buy front AND rear bushings if Kartboy can figure this out. Thanks!!! (thumb)

Here's an other solutions for the bushings problem. I tried it with succes.....for now.

Here it is: Cut a 1/4" slice of rubber from the middle of the bushing, where it's already open. Clean the bushing and the sway bar carefuly and apply a silicon grease between the bushing and the bar. When putting the bracket back over the bushing, I used the 1/4" piece of rubber and put it between one end of the bracket and the bushing. This make more pression on the bar and since there's less rubber on the opening of the bushing, it hold very tight to the bar.

Here's a little sketch og the mod:

stou thats smart. good thinking. i'm gonna try that if my bushing go bad again.

 

[SomaMP3]

Stou,

before i try this fix, i'm curious as to how long you've had the fix work(miles/kms).....and did you slip the rubber at the front of the bushing, or towards the rear of the bushing?

 

[Stou]

SomaMP3, I did this only 2 weeks ago. It's too early to realy know if it will hold for a long time. I did it because I had my bushings changed in December and something like 2 weeks later they start again to be loose and make lots of noise. So I decide to try this. I had nothing to loose.

About the piece of rubber, I don't think it can make any difference if you put it at the front or the rear of the bushing. The purpose of this pieces is only to make the bracket to push more on the bushing and make it hold better on the bar.

Still working fine!

Thanks Stou,

I'm taking your diagram to my dealership tomorrow
