Check the compliance bushings. They are known to crack and be shot by 100k on these (gf has one). Possible the person aligning it didn't notice or didn't care to tell you. Could cause odd things.

Yep...compliance bushings do show some signs of wear and do have cracks/tears in them. I rotated the tires this past weekend, and the front right was totally worn, almost to threads, on the inside at nearly a rounded 45 degree angle. The tire rotation did seem to lessen the symptoms, but they are far from gone. Might order new bushings here soon.

EDIT: WOW...control arms are dirt cheap. http://www.partsgeek.com/gbproducts/...ad=47433947772

Front rotors and brakes replaced 3 months ago...no excessive/abnormal pad wear or dust.

I got the bushings pretty cheap, like $10 a pop or something. If you have or know someone with a press its not a bad job.

Yeah my buddy has a press. I'm looking for a set of poly bushings for the LCAs but no one seems to make them. I figured the price of all 3 bushings vs $70ish shipped for a whole new control arm would be worth it.

with your mileage that absolutely makes sense and would make it a simple swap.

Problem solved! Most definitely was the front passenger side compliance bushing that was causing all the problems. My dumbASS cavemaned the LBJ removal though with a 3lb sledge instead of taking a minute to run to the store and spend $25 on a ball joint separator. This grave mistake cost me an additional 200 bucks in parts and labor. Essentially, I ended up having to have two new ball joints pressed in, plus replacing a damaged tie rod end. Lesson learned and I went by harbor freight and bought a BJT. All is well that ends well I guess, even though my pockets are lighter. Alignment is scheduled for Thursday. Steering wheel is crooked but man does getting new LCAs installed make a WORLD of difference. No more jerkiness. No more vibration. Completely solid now....all for what would have been $165 investment. If anyone has a FWD car with over 100k miles and you havent inspected your compliance bushings...go do it NOW. Worth every penny. Just be sure to use the right tools if you are doing the swap yourself.

Drivers side...worn and dry rotted, but far better than passenger side
