I have an hard noise like a METALLIC bump in the front right suspension on hard cornering too if it's compressed or fully extended.
No noise on normal cruise, too if the street is in bad condition.
I changed all sway bar bushing (powerflex) and checked for control arm plays but all is fine.
Shocks are stock, Kony yellows height adjustable (M030): what could be?

Could be your shock, mine (right front) made all kinda noises like that just before it failed completely (stock m474 koni with about 175000k miles on it. check for oil all over the outer tube and general area.Also check your ball joints , a bad shock will kill a ball joint after awhile....

The outer tube is absolutely dry and ball joint seems fine

Upper strut mounts?

joker2cv

I'm afraid that you are right! They are too expensive!!
If they must been changed i'll replace them with Camber plates much more cheap...

mj951

Agreed. When mine went I replaced them with Racers Edge camber plates...same price as stock mounts but yeah not cheap.

Today i installed two used but refurbished shoks and i can hear the same BUMP!
I checked all: sway bar, ball joints, tighten all nuts and bolts, checked wheel bearings.
Apparently all is ok, but the hard BUMP on left cornering is present again!!
What could i check?
Please HELP ME!!

Nobody?

Some common spots to check are the gap between the back of the transmission and the body of the car, the absorber bushings in the top of the front struts, the exhaust right after the down pipe where it passes the control arm pinch weld on the car especially if you have a bigger than stock exhaust, the crossover pipe in this same area if you have the 2-piece mod where the added flange is, your crossmember could be misaligned causing something else to hit the body or rails. Just some I've found over the years

Again, upper strut mounts? Have you checked your ball joints?

joker2cv

The shoks i tried are others than mine, ball joints checked 😁

So, what did you end up doing about upper strut mounts?

joker2cv

I swapped front shoks with others from a friend of mine and the BUMP is still there, so i think that the upper mounts are not the culprit.
I'm trying to find the problem...
