Knocking and chaffing sounds from suspension

nothing seems to be wrong but yet going over minor bumps and ridges in the road i often get a lot of knocking, chaffing and less often but sometime a heavy stressful squeek

if i go over smooth bumps it rides fine even if it is a heavy dip

wtf...

been like this ever since i put my susp on. Been on for probably 5 months now

this is probably a time consuming process to find out and i have none of that. Also would be pointless and wasteful to go to a shop i feel... I drive 30-60 miles a day on average and i've had enough of all this crummy sound >=( breaking my sanity.

I have been getting clunking noises also. I would check your end links first. I changed all of mine and found that one of them was shot to hell. It reduced the noise somewhat. If the noise persists, check your front sway bar bushings next. I am in the process of getting new ones also. If your car is low, it causes a lot of stress on these bushings. In short, diagnosing these things is a pita. Its a process of elimination. Hope this helps.

End links are a good place to start and the bolts need to be tight. You probably can't duplicate the sound by bouncing the car, but if the bolts are not tight and/or the bushings/joints are worn there will be the sound when encountering a sharp bump.

I'll keep in mind
- endlink bushings/tightening it
- swaybar bushings

But on another note would raising the car a bit help too, it seems my front susp could be really compressed too or is it fine to leave it as is? My front koni are on lowest perch while the GC coil sleeve itself is lifted up halfway on the sleeve. Although these might be better to judge with visuals, will be busy for a while before posting pics towards the night or later.

Side note: my don't think my car is too low in general and I have it set at what I see as proper height given my Commute routes. Just half a finger front and rear is about 3/4 finger. When fingering the well from a 45 degree angle

Tighten up the top hat nuts. I got alot of clunking from my Megans when I first installed them because the top nuts werent tightened down too well out of the box. Just take a half inch impact gun and zap em.
