This morning while driving to work I noticed that something just wasn't quite right. I kept getting the sense torque steer and what seemed to be intermittent wheel hop. Because I was driving in stop and go traffic and the shoddy state of most of the roads here in San Diego I couldn't tell if I was imaging things or if there was really something wrong? Later in the day I decided to do some investigating. Because of the torque steer I suspected that the issue was in the front end...
Maybe a bad strut?
Bad engine mount?
Front drive shaft?
Bad CV joint?
Lose front sway bar or control arm?
After spending 15-20 minutes digging around in the front end I was beginning to become paranoid. I did a quick look under the rear of the car but at first glance everything seemed fine.
I did some more driving on city streets paying careful attention to how the car was pulling decidedly to left with careful throttle modulation. At this point I was convinced that something was wrong but I had no idea what it was. I decided to risk it and take the car on the freeway to see if faster speeds would lead to more telling symptoms. Once I got the car up to about 55 MPH there was a very distinctive shudder and a repeated knocking noise coming from the rear of the car. I used my rear view mirrors to inspect the tires as I was driving. One glance at the drivers rear and I knew it was a bad lateral link or wheel bearing. I immediately pulled of the freeway and snapped the following picture:
So the question is, now that I know what is wrong, what should I replace the broken lateral link with?
