Hey guys!

My car has some suspension knocking noise which I've already spent countless night to figure it out and still didn't have any luck. Hope you guys can give me some advice.

And yes, I've used the search buttons thousands of times and I've check every related threads and done almost every advice people suggested before ...

Whenever I go over some bumpy or imperfect road, the knocking noise will starting to act up. The noise are mostly up front, a little bit noise from rear too (but not unbearable).

The car has a set of JRZ RS coilover with tender springs (150/500f and 150/700r) with mode inc camber plates, oem swaybars with TRG drop links. (These are all the aftermarket suspension parts I have)

The car started with some knocking noise from the suspension when I first pick the car up (few months ago). Owner said it could be the camber plates or drop-links.

So I picked up a set of front and rear mode inc. camber plates brand new, installed them, and the noise are still there.

We check ever bolts on the front frames and suspension area, they are all tighten down properly.

We disconnect the drop-links (front and rear). Drive the car around.
The knocking noise are still there and didn't change a bit.

I've change the spring rates, lube the swaybar bushing, and put some clothes between the springs and springs couplers to see if it changes anything. Still no luck.

So I beg you guys give me some advice on what to do and where to check next?

Thank you very much!

 

not sure what you mean when you said "disconnected" the drop links? did you replace them?? replacing mine cured the knocking noises i had.

 

I disconnected the lower bolt that connected to the swaybar and use clothes and zip tie to secured it so it wouldn't make any noise.
So since the drop-links doesn't have any force or movement on them after I disconnected them, they should quiet down if the noise are really from the drop links.
But no luck at all

 

i don't know enough about it, but i wouldn't use clothes and zip ties in an effort to cure my porsche turbo of knocking noises emanating from suspension components.. good luck man, i'm out of "help"!

but i would still REPLACE the drop links. ymmv.
