I have a 2000 Subaru Forester S model with 143k. I have been chasing a front end shimmy since we bought the car used a year ago. I have replaced the front rotors, and pads, cleaned and greased the caliper pins, made sure the calipers weren’t stuck, and had an alignment done. There was a bent front passenger wheel that I changed and had the wheels balanced. I have also checked the fuse for the ABS thinking that may have something to do with it. After the alignment provided no change I am stuck.
I just realized that I left out a critical piece of information as I was reading the posts. The shimmy is only under braking and is more pronounced under extra load such as down hill.
