So I’ve had the Swift Spec-R springs installed for about 3-4 weeks now and I’ve noticed some knocking noises when I turn the steering wheel a full turn left or right. The knock sounds come from both sides, not all the time, but periodically, I will hear it make a loud knock sound. Is this due to improperly seated springs within the strut/shock assembly? The car drives fine, even after completing a 600 mile round trip from NC to SC and back. The vehicle already had one alignment done, but Im about to get the Whiteline rear upper camber arms installed since the rears a a fraction off from spec. Any help in identifying what’s wrong is appreciated!

Lowering springs...help a momma out!

  • Looks like another user (OGGSR), in the above post, had similar clunking/knocking noise issues when turning the wheel with these Swift Spec-R springs. Already ordered the TEIN silencers for the springs. Going to try these out first since there doesn’t seem to be any functionality issue and the clunking/knocking noise doesn’t seem to happen all the time. Crossing fingers that this clears up the issue.

This exact thing happened to me on my 10th gen with my Springs, Coils, and Bags, the culprit was the sway bar links needing retorquing... and a little loctite, First thing I recommend you do is get the car in the air and check every bolt you touched during install Here are the torque specs for a X Gen they should be the same but I would double check for 11th gen. either way it should be good enough as a reference point for where your torque specs should be at.

Hope this helps!

You might want to purchase some tein silencers. They help some sounds as one goes over bumps and such. But even when everything is tightened it’s kind of just hit or miss with progressive springs.

I’m running D2’s with aftermarket shocks and I think they’re perfect, just had to get used to the sound. It’s only at low speed turns.
