Default Strange sounds after TiC/Kartboy Klunk Killer and Shift Kit Installed

Got the TiC klunk killer and most of the holy shift kit installed yesterday. For the Klunk Killer got the subframe outrigger bushings and the rear diff comfort version installed (complete). For the holy shift kit, installed the front and rear stay bushings, and the wide pivot bushing installed on MY06 Impreza 2.5i sedan. Now I noticed a couple of new sounds that aren't constantly there, but they are annoying since I'm a stickler for these type of noises. I will say though that the car drives so much better this way, no more bucking at really low speeds or during hard shifts. However, I have a couple of new sounds that I would love to get rid and I would be quite happy with the new setup. First off, there's a strange whine that I will hear once or twice, I think when the car has been sitting for a while. It appears to come from the passenger side, close to the centre of the vehicle (front to back), I would presume these are the outrigger bushings; maybe they weren't greased enough? The second sound seems to come from the same area, or close, and it's a gurgle type sound, which totally throws me off.

Anyone have any ideas on what these could be and how they can be rectified? Thank you.

The whine is likely the outrigger bushings. They do make noise sometimes.

The gurgling sound is probably fromt he stiffer shifter bushings. After installing our linkage update in my 04 wrx I noticed that sound on decel. Goes away if I put my hand on the shifter. I guess it's just the price we pay for increased bushing stiffness.

You can try more grease on the parts to see if that quiets them down. The comfort version of the KK is normally damn near silent.

Ya, that's one of the reasons why I went with the comfort version, I expected no change in NVH really. Which shifter bushing would likely be causing the gurgling? I really like the feel of the car, just wish it still sounded stock. I guess we'll have to try some more lithium grease, but that means taking them all out again.

don't use lithium grease as it will wash out. try a thicker wheel bearing grease.

So wheel bearing grease on all the new bushings huh? I guess I'll have to try that. Not gonna be fun taking everything apart and doing it again though, doh! Oh, is it gonna be 'easy' to remove the new bushings w/o mangling them, cause the originals were a real beotch to take out!

One more question, any issues with me driving the car like this till it's re-greased?

Lol, ya, I'll keep that in mind Tom.

I just really hope the thicker grease will do the job, I don't wanna go back to stock setup to get rid of the sounds, the car is sweeter with the klunk killer, the shift kit is nice, but I think I'm actually more satisfied with the KK than the shift kit.

Definitely. Did my SS, front and rear stay, along with TiC pivots last Wednesday. I don't even care about the additional "noise" now.

I dunno, I'm a stickler for this stuff, it'll prob bug me long term... But hopefully the right grease will take care of it.

I just had my race version TiC klunk killer installed on 06 wrx few days ago.
For the reference, I already had front and rear shifter stay busing prior to this and never experienced any weird sound whatsoever.
Exactly the same situation as yours, I am having some whining sound from between passenger side and middle of the car when I lift the throttle, especially when I drive it over 40 mph. The gurgle sound is heard when I "slightly" on - off the throttle at around little over 2000 rpm. But the gurgle sound disappears if I step on the clutch or shift into the neutral.
It seems that there is some mechanical stress in the tranny. Outrigger busings certainly restricted some free play in the back. And/so the front part of tranny has to take care of it. I am just wondering if the noise issue would get better if I install the rear differential busings later on. I am just curious if 02-05 wrx or sti expericence the same thing. Basically, I have never seen any 06+ owner mention about the klunking issues in the back. But one 06+ wrx owner did say the NHV reduced after he added the rear differential busings. And which is what I am going to experiment soon.

Keep us updated about your noise issue

One thing I will say is the front and rear stay right now are a little meh. I dunno, they're pretty stiff, and I actually think it's them causing the most NVH. One thing I know I don't like about them, feeling neutral is far more difficult than before. Is this something that'll get better over time, as in basically they'll loosen a bit from wear or is it always going to be this stiff? I may go back to the stock setup for the shift linkages. BTW, anyone know a good place to buy the stock bushings, my front bushing was a tough one to pull out, so I'd say it's probably a tad mangled.

Well because the shifter is stiff, I find the play of the shifter when it's in neutral is very limited, or I should say requires more force to sway left to right. That could be the pivot bushing I guess, maybe I need to loosen it more.

What did you torque the linkage to, and what did you torque the pivot to?

Additionally, were you sure you installed the rear shifter bushing correctly?

I didn't do it myself, a friend from the Toronto Subaru Club did it for me, he did it on his car a few months ago. What should they be torqued to? I'm going there again on Sunday to get things re-greased with the wheel bearing grease.

I wanted to ask, for the cross member bushings, on the MY06 Impreza, the two bushings to use are the ones that are of the same size, correct? Two of the bushings are the same thickness, and one is thin. According to the instructions, the thin is for the GC8, but the thicker one was used for the Forester.

Thanks.

For the linkage - 11 lbs.

For the pivot - so it feels good, but DO NOT exceed 8.3 lbs.

On the outrigger bushings - look at Peaty's instructions on Scoobymods. I know they are on a forester, but the same applies on the Impreza.

Thanks Clint/Tony et al, I followed Peaty's instructions, that's why I wasn't totally sure if maybe the GC8 bushings were for the new Impreza as well, but I guess we followed the right instructions.

So 11 ft-lbs for both the front and rear stay linkages? I read 13 ft-lbs on the installs.
I'm thinking things were just torqued too much, any probs, other than NVH from this, or am I going to be destroying my car?

Default 2007 wrx wagon 5mt SS noise

Hello to all,

I just picked up my new wagon today and had previously sent over a Super shift kit that I picked up from Clint the other day. The dealership installed everything for me ( front, rear and lever bushings with the exception of the front linkage bushings, which I will install myself tomorrow).

Here's the issue.

After getting in the car today, the shifter felt great but produces A LOT of noise in 3rd and 4th gears. 3rd is especially bad. I got myself under the car today to check the install and found that the front stay bushings (big round urethanes) are not of sufficient width to contact the bushing washer. I went to my local hardware store and found a perfect sized washer to take up the space and apply uniform pressure to the front bushings. After sandwiching everything back to together, I went for a test drive and still had quite a lot of noise.

At this point I decided that I would grind and little bit of metal away from the metal plate which sometimes gets in the way of the top shifter arm. After reinstalling everything, I went for another test drive and STILL had excessive noise while in 3rd and 4th. I'm kinda at my wits end here. If I place my hand on the shifter and pull down slightly while in 3rd, the noise goes away completely. 1st, 2nd & 5th don't seem to produce any noise whatsoever.

If anyone can shed some light on the subject I'd really appreciate it. I love the feel of the KbSS and really hope that I can get it to be as quiet as the stock setup, if not damned close.

Thanks in advance. And I don't want to hijack anyone's thread here, but felt that our problems might be similar. Cheer's

When you change to stiffer bushings you improve the shift feel. Theres a trade-off, it also increases NVH(noise vibration harshness). Just turn the stereo up and don't put your boogerhooks on the shifter till your ready to shift.

FYI, Feedback like this is actually desired by most scooby owners. I wouldn't be so quick to get rid of these, you might miss them down the road.

I can shed some light on this - pivot bushing. Make sure they changed those out for ours, and when they did they used the crush tube WE supplied with the pivot bushings, and not the stock crush tube.

when you reassemble tighten to feel, but do not exceed 8.3lbs.

Where are you located?

Thanks, Im going to go over everything piece by piece and will follow your recommendations and update the thread. It seems like quite a few have had this problem.

BTW, Im located in Houston, Tx - hence the accent.


And concerning the "crush tube," which part is this exactly, because as far as I know, the super shifter kit I got only came with the:
Shifter
Wide Sbushings
Pivot & Rear Stay bushings
and four other miscellaneous metal bushings similar to the shift lever bushings. I assume these are for the tranny linkage since there are four of them.

Alright, so got pretty much everything regreased and retorqued (aside from the read diff bushings). So far so good, no whine from the passenger side anymore, but the true test will be tomorrow morning, since the car'll have been sitting underground for hours and all cooled off. We greased the front and rear stay bushings and torqued em to the specs, as well as the outrigger bushings, using some nice thick, green, wheel bearing grease. The outrigger bushings, especially the right one appeared dry, so clearly the lithium grease was not the way to go, even though that's what scooby mods recommends.

The shift linkage bushings and the pivot bushings were also torqued and things feel much better. The pivot bushing is probably torqued around 5 ft-lbs or so, but I may tighten it up a tad more since I guess right now it doesn't feel that much different than stock, yes, more direct, but not stiffer I guess.

The only real NVH I see from these parts is fairly minor, at highway speeds it's a little louder (the gurgle I mentioned before, just not as prominent as before), in 5th gear, if you're out of the powerband, you'll get more vibration than stock if you're accelerating w/o downshifting and finally, it's a tad louder during engine breaking, or maybe it's a different sound altogether, not quite sure.

I really love the feel of the KK, that is a truly worth while install, the shifter linkage bushings, well, better yes, but not as much of a benefit as the KK in my opinion.

Anyway, hopefully things'll stay quiet, or better yet, get even quieter as the bushings go through their 'break in' period.

Just wanted to ask, is it normal to have the louder whine with this new setup on decelleration using engine breaking? I'm starting to wonder if this is normal or not. Going in for my 24k KM service soon and wanted to find out if this noise is considered normal or not, if it isn't, I may go back to stock setup and have the dealership look at the tranny. Thanks!
