Front suspension question

GM all, I'm looking for guidance with a front suspension question for my 2017 Sport 2x4.

For months, I've been trying to track down and eliminate a metal-on-metal noise in my left front suspension components. Heard only when driving over speed humps and bumps and when the suspension is fully activated. I now believe that the OEM springs are the source of the noise. I've replaced the OEM struts with Bilsteins 5100's, however, I reused the OEM springs and after a few months, the noise returned.

I recently picked up a set of low mileage used compressed OEM off road struts and coil springs (yellow and blue Bilsteins). While looking closer at the OEM off road springs, I noticed the a total of 9 coils, while the OEM springs on my Sport have only 8 coils.

If I'm correct and the OEM off road components eliminate the metal-on-metal noise, will I need to realign the front end do to the extra spring coil?

Thanks for your input, hopefully this will eliminate the noise.

yes, you will need the alignment after replacement.

 

Ok, will do. Thank you.

 

How much play in your drivers CV I to the diff? I'm suspecting this as a noise source right now. Do you hear it with the windows down only, I can not hear mine in the cab windows up
