I just put on a new wheel bearing on the driver side of my car. While coming off the freeway and putting on the brakes my steering wheel shakes, do you think I need alignment?
Shaking in the steering wheel WHILE braking is usually caused by “warped brake rotors” meaning the brake rotor is not evenly worn and the brake pads are moving in and out of the caliper causing the shake.
If you did not have this issue prior to the wheel bearing installation I would make sure you installed the bearing correctly, and put the wheel on the vehicle in a star pattern. Installing a wheel improperly can cause the brake rotor to not sit centered in the caliper. Using a star pattern to install the wheel is how it should be done.
You can replace the brake rotors (which are usually pretty cheap at your local auto parts store) or you can have your current rotors machined (trued) at your local auto parts store. I would replace the brake pads at this time so they wear evenly with the new rotors or newly machined rotors.
