[goralpm]

Hi
After replacing the broken coil spring i (left front), a strange sound appeared.
Knocks are not always heard.
Any idea?

First thing to check is the upper connection on the anti roll bar link for looseness. The nut can become loose, joint can wear but it sounds more free then joint noise. Can be checked with road wheel still on the car turn fully inwards/outwards turn car off remove key, then grab a hold of the link and see if it has free play.

Hi, Thanks for reply.
I check Anti roll bar and is solid.

But, I check everything for any loose and I find something,
When I get coil spring and try squeeze I hear exactly this noise. And fill like spring is moving, but in very barely palpable but palpable.
And after one squeeze is no noise or movement, but when I jerked is back to position when I could squeeze and hear noise.
Is feel like top mount of spring is not proper connected or putted and is some loose.
I marked where I squeeze with one hand.

The strut top nut can work loose..but that will result in a squeek/judder/skipping motion whilst turning the steering wheel.
Its possible the three bolts holding the strut bearing are loose.
Both these items can be viewed under the black plastic trim

Hi
Sorry for delete, but I was very byssy.
Ok.
I check every connection. All bolts and nuts are nice and tidy.
Other mechanic suggest it could be wrong coil spring.
Still looking for some solution's.

What spring did you use, from where? Did you do the heavy duty "upgrade" in the end after your queries last year?

I also had the suspicion it was an incorrect coil spring.

The best solution is get this booked into your local garage and get it fixed. You'll have your car back maybe within a few hours and be safe.

OK, one more update.
I was today in garage (same), after 8h garage change Shock Absorber and charge me another £140...
the mechanic said he should replace same time as coil spring, but... they just charge me another £47 for labour.
What is strange, when he change coli spring he charge me 1,5h but now 1h... Anyway.

So in couple of weeks I will be testing if everything is OK
