I bought a 06 honda civic si engine is DOHC 2.0l vtech and i've noticed a hard clunking and side to side sound on driver side on the car while driving and i replaced the driver inner tie rod because it was worn and also put some k-tuned control arms. and new pads and rotors. everything was great before and now i cant tell if its a wheel hub, cv axle, or the whole rack and pinion making that clunking hard noise and it's annoying because i just got my 2 years stickers yesterday. anyone can help because i think it could be the rack and pinion worn out but when i jacked up the front car to turn the wheels side to side to hear any noise but nothing seems fine i guess the noise only happens when i make a left turn and driving small bumpy roads especially through humps. please if anyone has the time to read and help a civic bro out that would be amazing of you like i kid you not and hoping this forum can help for future civic owners :)

I would have to guess something suspension wise, since its only happening under load and as well on bumps or humps. Possibly the shock or spring isn't seated correctly on the upper mount? My recommendation would be to jack up the front end to remove the load from the suspension and inspect the bolts where it mounts in the engine bay, compare it to what it looked like under load. If it looks like there is play in the bolts when not jacked and when jacked the bolts are flush with where they mount it may need tightened, could also be the rubber seat underneath the spring that has either gone or isn't seated right causing the spring to make a noise when compressing/decompressing against the lower or upper bracket stop. Other than suspension it might be where your rack and pinion mounts to the subframe that is making the noise? I couldn't imagine it is actually the rack and pinion since it doesn't make the noise without load. To check the wheel hub you could take the wheel off and wiggle the rotor up and down or side to side to see play, then remove the rotor and attempt turning the hub bearing without it on to see if the bearing has gone. Haven't had this issue before but these would be my recommendations

SO lol im driving it more to feel and understand what it is and i have to confirm its my rack and pinion because when i make a stop and stop sign and make a left or right turn and when i hear the noise i quickly just turn my steering left and right to wiggle it in a way to see if it is that clunking noise or knocking noise is from the rack and pinion and man when i felt it, i reallly think it is the rack and pinion or could be the endlinks of the swaybar. and it is suspension related for sure. wheel hub is fine and shocks and others ill double check tomorrow morning and let you know but my guess is rack and pinion like 90% percent sure its the rack and pinion. i even changed the inner tie rod on driver side just to pass inspection and should've second thought that maybe need new rack and pinion since i had to replace driver inner tie rod anyway so hope this all makes sense in a way, and im new is possible to upload photos and videos ??

For videos I believe it has to be a youtube link, but you can include photos. I just find it really weird its the rack and pinion if it doesn't happen unless its under load

underload? whats that because from what i saw this morning under the car its an EPAS (Electronic Power Assist Steering) its pretty much and swap and put it back on right ? because i have no steering pump or steering reservoir at all whatsoever and again im pretty new and new from buying this car and want to fix it up to the best like brand new car so i can drive it daily and also to have fun with her. please help :( and i think it is because i thought its an axle or the endlink of the swaybar because i did put it down when i installed the new control arms from k series. maybe adjust the swaybar with the endlink and maybe the endlink is hitting the control arm idk ? ill post a photos and video hopefully here tomorrow and hope you get the idea or anyone that reads this forum because i am loving this car its amazing and it has a stage 2 clutch in the new motor because the motor has been swapped from 110.00k miles i mean more now since im driving it but still its an amazing car in my opinion

Under load means the car's weight is on it vs without load meaning the car is lifted in the air. This normally shows difference between diagnosing an issue as suspension vs engine/steering/other parts not affected by the weight of the car.

ahhh i mean i would have to say yes because i do hear and somewhat feel the rack and pinion when i wiggle left and right when parked but not to crazy like that just left turn and right turn to feel it and it sounds nd feels like the rack and pinion and when i drive it down the road before turning in my neighborhood and did the same and i can hear and feel like its from the rack and pinion where the mechanic just swapped the inner tie rod on the driver side and still hear the clunking noise when driving. especiallly when i make a stop at a stop sign to turn left and right to wiggle a but to hear it and feel it and it feels like its coming from the rack but ill upload a video hopefully and send photos

But hey, these things will last eternities if kept up well, so you are right in wanting to keep it. I would personally bring it to a mechanic or 2 for a diagnostic at least and see their opinions if you have the time/money. That would be the most likely way to get it properly diagnosed, but I can definitely give my two cents on the topic if you get some video of the noise happening/describe where its coming from. A good way to know if it is the steering rack is whether or not you feel any looseness in the steering, any shakiness in the steering wheel (Not shaking from the car or engine), or that the car feels unstable at higher speeds

Yes, clunking is a side effect of a steering rack that's going/on its way out, but it can also be other issues that aren't 100 percent steering rack, did the noise come centrally from the car or did it come from a specific side?

nope not at all when i push it hard just a little to have some little fun until i fix the noise its fine no shaking on the steering but again when going to small or tiny bumpy roads i can hear the "clunk!" noise feeling it on my bottom left foot where the clutch pedal is because the car is a 6 speed manual

Hmm I would say inspect the other components down there like all of the bushings, suspension stuff, see if anything seems off. Does the noise at all sound like a clicking noise?

And if you aren't in a place plagued by lots of snow and rain (rain is alright) I would recommend a hybrid racing cold air intake and hondata/tune

On a repair, always start with the cheaper options, it could be the rack and pinion, but it also could be a worn cv axle/joint
