Hub swap to 4.5" bolt pattern completed in March 2017. Ever since, I hear a small thunk or thud in the rear of the car when a hard turn, or suspension is flexed (slight hill, etc). I didn't initially finish the parking brake so I believed that it was it swinging around, but it's fixed now and the noise is still there. Everything is torqued to spec, but still the noise. Anybody else experience it? Any ideas?
