The reason I asked about struts is that years ago the Monroe replacements had the wrong springs on them that made a noise when turning. No telling how old the stock is in the Czech Republic. The only way to tell is the correct ones have 2 ## or some other marks after the part number printed on the box.

 

Oh man, this sounds crazy...
Let me recap what I have changed and by what manufacture:
- I am ordering parts directly from US (rockauto or gmparts)
- struts / shocks - GM OEM both of them (example of single one GM GENUINE506288)
- coils - wasn't replaced yet
- upper strut mounts - KYBSM5513 https://www.rockauto.com/en/moreinfo...41024&pt=10444
- both sway bar links - GM GENUINE 20784686
- tie rod end - ACDELCO45A1062
- inner tie rod ACDELCO45A2206
- control arms both (example of single one MEVOTECHCMS50174 https://www.rockauto.com/en/moreinfo...441024&pt=7512

Today's short analysis:
- when car doesn't move and turn steering wheel on both sites no sounds
- when car is moving very slowly with wheels turned on any side (or slowly turning to any side) it starts to make a noise / cracking / knocking

@donbrew do you have any firther advice/ analysis / idea?

Thank you

Sounds like CV axle , could be bearing hub.

 

Thank you Oldblue. Just thinking about it and I am sure I am missing something:
- in case of CV Axle - it will be problem directly with the CV Axle itself (both of them) or something else where CV Axle is connected to (in manual transmission in my case)
- in case of bearing - here I am convinced it is not bearing hub (I tried to handle wheel left - right / up-down => no movements)
- in case of upper strut mount - it sound very interesting to me (based on @donbrew idea) if it could be case when I have installed KYB mounts including bearings
- in case of rack & pinion => does exist any test / excercise how to check rack status?

thank you

Hello,
Update and Warning

Finally I found the source of those crazy sounds. The story in brief:
- I went to technical inspection with HHR
- the technican told me that front lower joints on both side are very worn, but I did replace whole control arm together with ball joint from Mevotech CMS50173 and CMS50174
- I decided to replace ball joints by new one from ACDelco
- yesterday I replaced both of them => no crazy noise anymore

The result is that even new control arm including ball joints from Mevotech in Supreme versio, it could be damaged somehow.

I will go only with OEM components where possible.

Glad you found the issue! Enjoy the ride!

 

This dampens my hope that the Mevotech "Supreme" line might become a go-to. Would love to inspect those ball joints to see what's wrong. Mevotech should want to, as well.

 

I had a similar experience with no-name LCAs some years ago, the same ones that had a camber problem.
I always thought Mevotech sold "collision" parts.

 

They are stepping up their game, the TTX hubs are doing well, but it’s early.
