Timothy.B Posted November 29, 2016 Share Posted November 29, 2016 It's the OEM Subaru noise. I've talked to a few other people that say the exact same thing happens to them. It happens when I go forward too but I'm usually parked in a spot where I have to back up. It's not really felt in the seat but it's audible.

I did momentarily when I did the sway bars but I went around and retorqued all the endlinks and no issue since.

GTEASER Posted November 29, 2016 Share Posted November 29, 2016 Timothy, you are talking about he drivetrain clunk that other 3.6R guys have too, Golfer and Humble. This thread is about a left front suspension "pop" that some of us get.

dohclgt Posted November 29, 2016 Author Share Posted November 29, 2016 (edited) Got my kca313 roll center kit. Looks really nice. I was planning on getting the superpro but since there was a sale, picked these up instead. Will try SuperPro kit after these fails lol.. Edit: I was able to cancel the OEM LCA I ordered yesterday. In turn, I ordered the AVO Caster bushing kit as recommended by Gteaser and others. http://www.avoturboworld.com/catalog/product_info.php/products_id/128 Edited November 29, 2016 by dohclgt Link to comment Share on other sites More sharing options...
bloodwingg2 Posted November 30, 2016 Share Posted November 30, 2016 I also hear that clunk / pop after lowering my cars. My setup right now is Stock struts with S.Techs. But everytime I turn left I hear that clunk / pop and I already get used to it right now. Checked them and nothing loose. Keep in mind that I also changed my springs on 20k and heard that sound after that. Link to comment Share on other sites More sharing options...
FLlegacy Posted November 30, 2016 Share Posted November 30, 2016 Maybe tomorrow I will get out a can of wd-40 and track down the thunk, lol. I need to tighten up my rear shocks too. Im gonna start with the LCA bushings, mine are well-weathered. Link to comment Share on other sites More sharing options...
dohclgt Posted December 1, 2016 Author Share Posted December 1, 2016 (edited) So, I just finished the whiteline roll center kit. Started at 10pm and finished at 12am. This is me taking my time inspecting everything else AGAIN to see if I missed anything that could have caused that stupid sound. Im still suspecting it's the H&R spring binding... Bushing looks good still. So many suspects.. My new tie rod ends, only like a damn month old.. -.- Same with my ball joint.. Anti-seize made my life alot easier than the first time removing it.. Torqued the ball joint to 40ft/lb (I know its like 37ft/lb but i just rounded it off..) and the tie rod ends to 30ft/lb (Feels like 19.9ft/lb just isnt tight enough or did I got wrong tq specs??)

Unsp0kn Posted December 1, 2016 Share Posted December 1, 2016 Haven't had the pop on stock struts yet, it's pointing towards something with my coilovers. Further investigation is needed. Link to comment Share on other sites More sharing options...
Golferdude1087 Posted December 1, 2016 Share Posted December 1, 2016 Ok, so after about a week I can report back. AZP said they believed it could be binding so they sprayed it to loosen it up. The pop/clunk is gone, the only noise I get is the typical sounds you get when turning the wheel and the car is not moving. I am working on getting ahold of exactly what they sprayed and where.

dohclgt Posted December 2, 2016 Author Share Posted December 2, 2016 So I've been driving around a bit today, my normal routes and so far no clunk/pop sound yet! On a side note my Eibach Springs came in today!! Glad to know they're made in the USofA! I won't be installing these yet if ever as long as there's no clunk/pop noise. If the sound comes back, I will be installing these, pursuing to find the cause of that stupiiid noise! Link to comment Share on other sites More sharing options...
FLlegacy Posted December 2, 2016 Share Posted December 2, 2016 The Eibach neither cause nor cure the noise, just put them in already! Link to comment Share on other sites More sharing options...
GTEASER Posted December 2, 2016 Share Posted December 2, 2016 The Eibach neither cause nor cure the noise, just put them in already! He's already running H&Rs, the Eibachs were to try if he finds the noise doesnt go away with other things hes trying, thus trying to rule out the H&Rs as the culprit.

FLlegacy Posted December 2, 2016 Share Posted December 2, 2016 Well lets see, its happening on stock springs, H and R, Eibach, and coil-overs...not sure what other proof he needs...I think you were on the right path with the lca bushing or thereabouts.

GTEASER Posted December 2, 2016 Share Posted December 2, 2016 I took a right hand corner to hop on a freeway on ramp this morning, and the pop occurred just as I turned in and the suspension loaded up at about 30mph.

dohclgt Posted December 2, 2016 Author Share Posted December 2, 2016 OK, so, update: The pop sound came back this morning as I pull out of my driveway. It made a louder pop sound this time. Also, it's more frequent. I can somewhat replicate it when I want to. So I'm beginning to think it's the left LCA (Just like GTEASER and other members suggested). I think the ball joints have caused the LCAs' geometry to be different causing the pop noise more often. So, I'm going to go ahead and install the Eibach springs as planned anyways, just to be sure it's not the springs binding. Then I'm going to install the LCA bushings and go from there.. BTW, I definitely need an alignment after installing the Roll Center Kit. My alignment is so off it's scary driving the car. I could smell my two front tires burning off after a short drive!

GTEASER Posted December 2, 2016 Share Posted December 2, 2016 Why don't you do the AVO bushings first? If that fixes it, then you haven't wasted a buttload of time and effort swapping the front springs, and you can just leave the H&R's in.

The truth is, Im just dreading the install of the bushing into the LCA.. Furthermore, I have the springs here. I can install the springs within a few hours easily compared to the LCA. I have to find a reputable shop locally to press them in correctly. I guess I'm just hoping it's NOT the lca. Link to comment Share on other sites More sharing options...
Ellesedil Posted December 3, 2016 Share Posted December 3, 2016 The question I have is: which spring do you ultimately want to run? If it's the Eibachs, then fine, install them. If it's the H&Rs, then leave them investigate more likely culprits. Link to comment Share on other sites More sharing options...

Brb, installing them now. Link to comment Share on other sites More sharing options...
dohclgt Posted December 3, 2016 Author Share Posted December 3, 2016 Finished the install. The rears were more of a pita than the front but still easy. H&R setup Top hat with the washer. No visible length difference.. Seems like they're the same length.. All in. Test drove it. I'm now certain it's the LCA. Installing these springs did not change the tone of the pop/clunk sound like changing the ball joint did. The EIbach springs seemed stiffer than the h&r, maybe because it's new? Other than that, I can't really tell the difference between the two. I definitely need more drive time to tell though. The Eibach springs made the car looks so high again but my lady likes it because I didn't scrape my rally flaps going out our driveway lol.. Next up, LCA bushing. :spin: Link to comment Share on other sites More sharing options...
Norm Peterson Posted December 6, 2016 Share Posted December 6, 2016 Have you guys checked the location of the very end of the bottom coil of the spring? Norm Link to comment Share on other sites More sharing options...
