Suspension noise under hadr accelleration/braking - Pls help

Hi there all.

My car is making a loud "cluck" noise when I accellerate hard and then the same noise if I brake hard??? I have replaced the control arms, the schocks and the car has a slightly dropped front suspension with firmer springs. If I accellerate normally all is fine....it`s just when I hammer the car. I have been under the car and i have tightened EVERY suspension bolt I could see, including the ones that hold the subframe to the body itself - still the same "clack" noise???

Any ideas on this anyone???

is it not your drive shaft what makes the noise?

Or maybe your diff..

If it was making the noise under accelleration only I would think it could be, but it does the noise thing when I also just brake hard - therefore I tend to think more suspension???

control arm bushings are probably busted... common problem with nubiras down here

Wishbone bushes or loose wishbone back bolt. That, or the ball joint in the wish bones fooked. Could also be the strut top too thinking about it.

I have replaced the complete control arms about 10 000KM`s ago. Granted these are not designed for 264KW/477NM on the front wheels

The car has done 330 000KM, and I have never changed the "top shock" mountings....maybe I should look at this????

Yeah, check to see if the 2 strut top bolts are tight. I've heard them knock under braking and accel. But really, check your control arms, or wishbones, whatever you like calling them. I'm still leaning towards that.

Thanks Pir0 - the top bolts on the shock mountings are tight - checked them. Will check out the control arms and bushes - hopefully nothing can "fall off the car" whilst running my 1/4 mile @ 180KM/H
