stanghater Posted July 30, 2010 Share Posted July 30, 2010 Ive been dealing with this issue for about a year now. When braking, especially at high speeds there is a pretty bad shaking in the steering wheel. Initially i replaced the rotors and pads... still there. Then we wanted new rims and tires anyway, so I go them.... still there. THen i had some brembos that i had meaning to install on the LGT so i did with new rotors and pads..... still there. One thing i did notice is now with the brembos, when i lightly brake the shaking is there but the harder i press the brakes it stops. SO in my mind, no matter what anyone says ITS NOT THE BRAKES. I did a quick once over of the sway bar bushings and stuff, i didnt see any broken/torn ones. Could this be a bad strut/tophat? Link to comment Share on other sites More sharing options...
Nachowang Posted July 30, 2010 Share Posted July 30, 2010 A tear on the lower control arms perhaps? Link to comment Share on other sites More sharing options...
Max Capacity Posted July 30, 2010 Share Posted July 30, 2010 OK I won't ask if you re-bedded the brakes, because apparently the shaking still happen the "first time" you stopped with the new brakes. I would doubt it's top hat's, you would hear more clunking if it was IMO. I would think may be bushings in the LCA.

RochNY91TSI Posted July 30, 2010 Share Posted July 30, 2010 Could be the wheel bearing Link to comment Share on other sites More sharing options...
Max Capacity Posted July 30, 2010 Share Posted July 30, 2010 I'm thinking you would hear a wheel bearing going bad, this problem has seemed to been around for a while for reading the post. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.

Dunno, just throwing an idea out there. There's only so many things that it could be- Brakes (seem to have ruled those out through changes of pads and rotors) Tires / Rims (seems to have changed those too) I'd guess that it's likely something connected to the wheels, so that leaves the bushings as mentioned (plus steering rack) and the bearings. Maybe something with the wheel hub... Link to comment Share on other sites More sharing options...
stanghater Posted July 30, 2010 Author Share Posted July 30, 2010 ill check out all the bushings there more thoroughly this weekend. I am at the point now where i would pay anyone any amount of money to fix it. ARGH! Link to comment Share on other sites More sharing options...
LowFast Posted July 31, 2010 Share Posted July 31, 2010 ill check out all the bushings there more thoroughly this weekend. I am at the point now where i would pay anyone any amount of money to fix it. ARGH! I have the same issue, have checked the brakes, changed the LCA bushings, struts are new, wheels are new, tires are new and balanced, new tierod ends and balljoints. I really don't want to change the wheel bearings, $$, and still have the issue. When in the air there is not play in the mounted wheel, and no noise, squeal, when driving. I feel your pain brother.

stanghater Posted August 23, 2010 Author Share Posted August 23, 2010 Just an update. It was both lower control arm bushings. They both were BROKEN. WTF subaru? Link to comment Share on other sites More sharing options...
LowFast Posted August 23, 2010 Share Posted August 23, 2010 Upon independant check mine is a set of warped front rotors, not sure how it happened but I have an idea (crazy tire shop over torque of the lugs) so I need to either have them turned or get new ones. Thanks to the guys at COBB plano for running this, and a few other issues, down. Link to comment Share on other sites More sharing options...
kram Posted August 23, 2010 Share Posted August 23, 2010 Just an update. It was both lower control arm bushings. They both were BROKEN. WTF subaru? Was the shaking ONLY when braking? Or did you get shaking at highway speeds too? Link to comment Share on other sites More sharing options...
05bikemobile Posted August 26, 2010 Share Posted August 26, 2010 Just an update. It was both lower control arm bushings. They both were BROKEN. WTF subaru? What did it cost you to get them replaced? did you get stock bushings or something aftermarket? Mine does the same thing. Link to comment Share on other sites More sharing options...
codger2 Posted August 30, 2010 Share Posted August 30, 2010 My 06 LGT wagon developed this over a driving/camping/hiking holiday from Calgary to Washington state. It may have something to do with some of the rough gravel backroad driving. Only get the shake on hard braking from highway speed, especially noticable on steep downhills. will be looking at it later today. Link to comment Share on other sites More sharing options...
Mega Users LieutenantDan Posted August 30, 2010 Mega Users Share Posted August 30, 2010 9 times out of 10 this problem is due to tears in the LCA bushings. Happened to me around 60,000. It got so bad that the entire front end started vibrating at all speeds while I was driving it to the shop to get them replaced. I just had them replaced with oem parts. I hadn't done any suspension mods at that point so the next time they need replacing I'll probably go with aftermarket parts Link to comment Share on other sites More sharing options...
06wrxlbart Posted August 30, 2010 Share Posted August 30, 2010 Has anyone tried installing a lower chassis brace to eliminate the vibration? Link to comment Share on other sites More sharing options...
stanghater Posted September 13, 2010 Author Share Posted September 13, 2010 I got the avo bushings from fred beans. They were 145 i think... maybe 120. i dont remember, i also got the front ones to since i was doing it Link to comment Share on other sites More sharing options...
06wrxlbart Posted September 14, 2010 Share Posted September 14, 2010 I think stiffer bushings will make the wheel shake more wouldn't they? Link to comment Share on other sites More sharing options...
05bikemobile Posted September 15, 2010 Share Posted September 15, 2010 i think the bushings be being loose/worn is the reason the wheel shakes. toe in/out movement when braking. Link to comment Share on other sites More sharing options...
amp27 Posted September 18, 2010 Share Posted September 18, 2010 do you need a press when changing the LCA bushings.. i have this problem and thought i would just change the brakes, i was pretty hard on 14 year old rotors, clogged with rust.
