LittleBlueGT Posted December 15, 2008 Share Posted December 15, 2008 http://legacygt.com/forums/showpost.php?p=1930537&postcount=62 ~$290 per arm. 6.6lb weight savings! That is a lot of money, especially since we need two! Full tune of 68HTA, KSTech 73 MAF, Racer X FMIC and ID1000s................by the DataLog Mafia!!!

Leonardo Posted December 15, 2008 Share Posted December 15, 2008 or $35.00 (msrp) for the two bushings if the arms seem like alot. Link to comment Share on other sites More sharing options...
Guest Posted December 15, 2008 Share Posted December 15, 2008 I have stock trailing arms I can sell if anyone wants to minimize downtime. Would sell them cheap, although they are heavy so shipping will cost a bit. Link to comment Share on other sites More sharing options...
Leonardo Posted December 16, 2008 Share Posted December 16, 2008 (edited) Just looking at the 2 posted sub-frame diagrams and the one I have here from the dealer I think more like Seeeeeya, it;s got to be the trailing arm bushing as the sub frame is a much more heavier unit and held in place by 4 mounts and the rear brace plus the two front ones that look like little J's and the other possible movement or flex would be the trailing arm wanting to "dance" back and forth (judging by the opening on the bushings) with the power or torque because when there is wheel spin (wet surface), it does not move because there is no resistance. Wonder how that bushing is on the 08STi since we share almost the same suspension. Edited December 16, 2008 by Leonardo Link to comment Share on other sites More sharing options...
Underdog Posted December 16, 2008 Share Posted December 16, 2008 That is a lot of money, especially since we need two! I bought mine with subybucks at 75 cents on the dollar... Took some of the sting out of it. I also have by stock arms if anyone wants to experiment with them. There are pics in my FS thread.

schwinn Posted December 17, 2008 Share Posted December 17, 2008 I assume I'm the "one of two 06"? If not, then I should be #2 of 3... Link to comment Share on other sites More sharing options...
rony Posted December 17, 2008 Share Posted December 17, 2008 Um.... Statically 1 or 2 Spec B's with issues is not a confirmation that Spec B's are having this same problem. My Car vBGarage Link to comment Share on other sites More sharing options...
Guest Posted December 17, 2008 Share Posted December 17, 2008 True, except I doubt there is enough production variance that would be responsible for the growl. A car either has it or doesn't. Note, not a single MY07+ owner complaining. Link to comment Share on other sites More sharing options...
dvdt Posted December 17, 2008 Share Posted December 17, 2008 I count one 07. I have a USDM 07 and i get the noise under hard accell only when the car is cold. Link to comment Share on other sites More sharing options...
LittleBlueGT Posted December 17, 2008 Share Posted December 17, 2008 So I wonder if the better bushings that the specB has in the rear arm just is part of the solution to the problem? Maybe a spec-B owner could get the WL diff inserts as well? They are only like $30? Full tune of 68HTA, KSTech 73 MAF, Racer X FMIC and ID1000s................by the DataLog Mafia!!!

schwinn Posted December 17, 2008 Share Posted December 17, 2008 So you have a spec-B? Have you done anything to solve the problem? Doh... maybe I misread... I thought it was saying 1 of 2 MY06 owners... not specB owners. Bottom line, no I am not SpecB... but I do have the growl on my 06 LGT. I'm going to be getting some high-density rubber pads, about 1/4" thick, and will see if I have the inclination to install them on the subframe mounts during this cold winter weather. I have 2 weeks off from work for the holidays, so I might have an opportunity... we'll see. In the meantime, I'll keep checking in on this post, hoping someone else has more initiative than I do!

His post here http://www.legacygt.com/forums/showthread.php?p=1830889&mode=linear#post1830889 indicates that he calls it a "vibration". (Of course, he doesn't mention he's SpecB there, or within his info.) I would agree, mine sounds more like a vibration than a growl... it's not as "smooth" as a growl... you can hear the "spaces" between the "events" rather clearly. (Implying that a "growl" has little or no "space" between the noise "events".) In other words, it sounds more like a high-rate clattering or metal-to-metal noise... hence why my mechanic theorized the subframe was the culprit... though the "#13, Rear arm front bushing" described by SeeYa in his schematic is certainly another possibility, as mentioned before.

It isn't that bushing in and of itself that is actually making the noises, although it contributes to the symphony. It is what their lack of support for the rear wheels' alignment enables, which is a rapid, repetitive, back and forth fight for traction between the wheels that loads and unloads the entire drivetrain. This causes the two piece driveshaft assembly to move about in its extremely loose rubber mount as well as virtually every other rubber mounted component in the entire rear of the car. Those top rear diff bushings dance to the same baton. Give the wheels equal traction, all the time, under all power inputs and you can go quicker, too. BTW, your description of the noise is very good, reflecting my own experiences which have gone but are not forgotten. Link to comment Share on other sites More sharing options...
Leonardo Posted December 18, 2008 Share Posted December 18, 2008 And funny how it's only on right handers (at least most of us) and under load (those of us with lots of power). Link to comment Share on other sites More sharing options...
SeeeeeYa Posted December 18, 2008 Share Posted December 18, 2008 And funny how it's only on right handers (at least most of us) and under load (those of us with lots of power). Yes, and no. Every car has a tendency to lose traction on one side first, turning just exacerbates that fact and starts the chain reaction easier. And under load, of course, while again it starts on that one side first, that extra power overcomes the greater traction straight forward motion provides.
