__raj Posted June 21, 2012 Share Posted June 21, 2012 My wife's 05 LGT wagon 5mt(132k) has an intermittent vibration 65-80MPH. Our first step was rotating/balance tires (35k Conti DWS) and no change. What else should I be looking for??? She simply speeds up to 80 MPH. My wife took an iPod video of it if that helps any.

eurolatin33 Posted June 21, 2012 Share Posted June 21, 2012 i would check rotors, before you get into the expensive stuff. i did quite a few things and last week my mechanic looked at my car and found out my rotors where out of round due to rust from the crappy cast iron rotors on our cars. Unfortunately i didnt get to change the rotors due to the incompetency from a certain store as they got me wrx rotors when i specifically asked for leggy gt.

doctorbrody Posted June 21, 2012 Share Posted June 21, 2012 I actually have the exact same issue, same mileage. My wheels haven't been balanced/rotated recently so I can't rule that out. But I did get an alignment and replaced my worn rotors and that helped but didn't solve it. Also at 125k miles I had to replace my driveshaft which was causing intense vibration above 40 mph.

jhawk222 Posted June 21, 2012 Share Posted June 21, 2012 My first thought was to rotate/balance and align to see if it disappears. Link to comment Share on other sites More sharing options...
BigBad Posted June 21, 2012 Share Posted June 21, 2012 Another thing to check is a partially frozen front caliper piston. usually one of the two on one side won't fully retract which will cause a vibration like that in the steering wheel. Happened to me twice. Link to comment Share on other sites More sharing options...
turbodog Posted June 21, 2012 Share Posted June 21, 2012 Check for excessive rust around the edge of the braking surface. This can be wearing into the pads and will cause an intermittent wobble. Link to comment Share on other sites More sharing options...
Moderators BarManBean Posted June 21, 2012 Moderators Share Posted June 21, 2012 Why are brake/rotor issues being brought up if the issue is only occuring at 65-80 mph. Stuck caliper I could understand, but I think there would be other symptoms of that as well. I'm in the 'bent wheel' camp. A slight bend may be producing a harmonic type vibration that is evidenced most strongly at the speeds you indicate. The balancing machine likely isn't replicating these speeds so it's also not replicating the harmonic motion. Your wife hit any potholes recently? You could try rotating tires to see if the vibrations moves from the wheel (problem in the front) to the seat (problem in the rear). Worth a shot since it's essentially free.

20sti04 Posted June 21, 2012 Share Posted June 21, 2012 You sir, definitely need a balance! LOL Link to comment Share on other sites More sharing options...
theflystyle Posted June 21, 2012 Share Posted June 21, 2012 this is happening to me too!!! rotors are new, i noticed it after a tire rotation so im thinking a balancing issue or something related to a single wheel Link to comment Share on other sites More sharing options...

landark Posted June 21, 2012 Share Posted June 21, 2012 Is there any difference on the amount it vibrates when you rotate? I have either a bent rim or out-of-round tire and it does something similar. It vibrates from the rear when on the back but there is a noticeable difference from when it's on the front. Link to comment Share on other sites More sharing options...
LegacyWGTW05 Posted June 21, 2012 Share Posted June 21, 2012 I would say rotors. Link to comment Share on other sites More sharing options...
cseagle08 Posted June 22, 2012 Share Posted June 22, 2012 Balancing & Rotation were first attempt at fixing. No change. What kind of balancing was done? I ask because my first 3 sets on various cars I used to get the regular 'computer balance' and I always had a horrible imbalance between 70-80mph on every vehicle. The last 4 sets of tires I have gotten I've had them Road Force Balanced with the Hunter GSP9700 balancing machine. I never needed a re-balance during the entire life of any of those tires.

plumb Posted June 22, 2012 Share Posted June 22, 2012 do u have any dirt built up on the inside of your rim? cause if u do it will throw it off balance and cause it vibrate. it happened to me and i only noticed it at freeway speeds it got to the point where i let go of the steering wheel and watch it shake back and forth Link to comment Share on other sites More sharing options...
Gmoe Posted June 22, 2012 Share Posted June 22, 2012 OK I think I'm having this too. It's very intermittent and at random speeds when it does show up, then out of nowhere is just goes away. Doesn't show up again for weeks sometimes. I'm going the caliper route as when it happened the other day I pulled over right away and there was a LOT of heat coming from the passenger front wheel.

A_Tang Posted February 26, 2013 Share Posted February 26, 2013 I have the same problem now, after the dealer put in some new control arm bushings. The vibrations were ever so slight before this work, and after I put on new wheels and tires, rotors and pads in Nov, were almost non-existent. But, after the bushing install this past Feb, the steering wheel has been shaking hard at speeds over 50mph. Sometimes they seem to get worse as I move through slight corners at high speed, and sometimes they seem to go away for a short period of time. I took the car back and they checked the wheel tire balance and alignment again. The service advisor said that I have a aftermarket pads, rotors and rims so they aren't liable. The tech wrote on the reciept that its possible I have a bad CV axle or wheel bearing. Thoughts? Thanks Al Link to comment Share on other sites More sharing options...
stuck686 Posted February 26, 2013 Share Posted February 26, 2013 i had a similar thing on an older car and it turned out to be a rusty control arm on its way out. most likely not the issue but throwing this out there Link to comment Share on other sites More sharing options...

Gmoe Posted February 27, 2013 Share Posted February 27, 2013 The shaking you had experienced...did it seem to come and go as you cornered? No it didn't, and it wasn't every single time I drove, it was random on and off, though it got worse over time. Link to comment Share on other sites More sharing options...
Gmoe Posted February 27, 2013 Share Posted February 27, 2013 What was the fix for this? Easy? If you know how to do brakes and/or are mechanically inclined...yes it was easy relative to working on a car. THE biggest pain in the ass I had is finding the right part replacement part being I didn't want to buy a BBK. I found many sites listing the 2.5i caliper upgrade available with dual pistons as the replacement for the OEM caliper on the GT. They are not the same because the rotor diameter of the GT is larger. I'm now having exactly the same issue, and it's the opposite side. I shoulda done BOTH when I did one!! A tell tale symptom of it being the caliper is... Pull over soon after or while it's happening.. feel your wheel. Mine got VERY hot, I didn't even have to touch the wheel to be able to tell it was getting crazy hot which = sticking caliper.
