Steering Jerk when touching brakes

E91 Hoarder · 04-15-2024, 09:17 PM

New brake pads and rotors, recent alignment, control arms are good.

There is s slight steering wheel jerk when slightly pressing the brake.

No vibration during hard braking or driving high speed.

Any clues what causing it?

I was going to say control arm bushings, but you already mentioned they were good.

Yup you need to replace the rearward control arms (torsion arms). The bushing where it connects to the frame is bad. Do both sides and also do the 2 "dog bone" arms while in there. Make sure that you tighten everything with the car at ride height or you will damage the new rearward control arm bushings.
