Hi vanib,WD40 is not the best for lubrication.
If you suspect rust, spray some PB Blaster.
For actual lubrication, I usually use silicone grease or Sylglide brake grease but that might not make it to the right places in such a tight spot.
Which dry lube did you use?
Also wondering about this. My 2015 Limited makes a squeak and stops going up/down in the middle of operation about 90% of the time. I'm gonna try lubricating the struts and hopefully that'll do the trick.As anyone managed to fix the sticking strut and anti trap that stops it from going up?
When it sticks it takes several attempts to get the boot to open.
Also is it possible to change it to a ordinary gas strut ,I would like to know if anyone as tried .
