rattling/knocking sound coming out fr front left wheel

hi everyone, need some suggestion/help here

sorry for the long title, it is a little hard for me to give a title to this problem.

here's the problem, there's rattling/knocking noise coming out from the front left wheel or chassis, not sure which one. what i meant is, whenever i make a right turn, doesn't matter if it is a hard right or just a normal right turn (speeding or not speeding) and when there's a load or weight onto the front left, there will be some rattling or knocking sound.

when i am traveling on straight road, even thou it is bumpy or uneven, there isn't any noise at all, only when i make a right turn.

sorry of it is confusing, this is the best i can explain for now. i'll think up something better to improve.

have been having this problem for more than a month now. so this is what i have done so far.

1. Initially thought it was my suspension, so i decided to change to an aftermarket ones (wanted to change sometime ago anyway), but doesn't solve the problem.

2. remove anti-roll bar, and re-install again. and changed the i-link, doesn't solve.

3. changed the wheel bearing.

4. changed drive shaft.

5. since i am running on 18", check if there's scrub, no scrub, no sign of scrub on the tires or the inside arch.

6. tighten and double checked if there's any loose bolts/screws/nuts.

All above has been done but doesn't solve it. The only thing i am yet to do is change all the bushes and check the tie-rod. Reason i have yet to touch these 2 parts is because if there's problem on these 2, there will noise coming out, doesn't matter there's load on the front left or not or doesn't matter if i make a right turn or not. (correct me if i am wrong)

Anyone has experience this problem before?

oh almost miss this out, this problem does affect handling. it makes the front left unstable and the rattling/knocking noise will go louder if there's more load onto it.

Sounds alot like it could be a bent wheel. Not bad enough to notice when going straight. You might try putting the spare on in it's place and see if the problem is still there. Or you can rotate the wheels and see if the vibrations and noise move with the tire.

Check out my wheels today, alignment check throughly, camber check as well, wheel balanced and swap front wheel to back. Still same, doesn't solve it.

Did you inspect the tie-rod and bushings as in your first post?

it happens to me once that my right hand side front wheel gives some odd vibration during turning.cant feel it on the steering wheel as well.not long after it started to give some weird sound as well when turning . have it checked out its my power steering pump leaking.have it sorted out and no more vibration and sound.
no harm checking it out.

not sure if ## problem has been solved yet but i used to have this problem in my car. Do you have a strut tower bar? if so check to make sure it is tight cause mine was coming losse witch caused the vibration. and if you dont check yous struts to be sure they are tight anyway.
