Is it the lower or upper control arm that causes shakes

[chivas]

Thanks everyone! I went to a local shop that had road force and it did cost more but it was totally worth it. No more shaking from the front but the rear tires will be replaced as it's some no name whatever brand and has a flat spot even though I've been driving her 400 miles each way for work.

Of all different cars I've driven (been renting cars for work before picking her up) everything felt like a car. Driving the X (or an older BMW for that matter), it feels like I'm driving a machine. Ineffable to those that never have driven such a piece of engineering. Don't get me wrong, I still love driving my 95 Bronco and she serves different duties. Difficult not to bring her in the triple digits when everything works right. Dat torque!
