Default 2016 wrx- knocking in front suspension

knocking noises heard at slow speeds over barely rough roads.
-left front strut replaced at 3,000 miles
-dealer stated a TSB came out for strut mounts (replaced at 15k)

I had the issue of some knocking noise going over barely rough roads, however it wasn't from the suspension.

My issue turned out to be the steering rack, which was making the knocking noise. It only happened at slow speeds and small bumps here and there.

It was initially detected when you wiggle your steering wheel left to right quickly (I'd say within an inch of rotation in either direction) all while the car is completely stopped, which recreated the sound I was hearing while driving over bumps slowly.

The dealership looked into it and ended up replacing my steering rack and the noise went away, for a while.

Perhaps you may have a similar issue?

Sorry to revive an old thread here, but I'm curious what became of your issue. I have a 2016 WRX Limited and also had the strut mounts replaced at about 15k miles. Fast forward 3-4 months and 5k miles and the noise is back and I'm guessing they're broken again. I'll know for sure on Monday when I go to the dealership. Doesn't inspire much confidence...
