I got a set of 4 for my JKU, installed the rear two on Sunday (ran out of time and patience to complete all 4) - when I first put them in, they did the proper 'detent', but Sunday night when putting the soft top back up after a mild offroad run I noticed they were just 'resistance', not 'detent'. I emailed StarFab about it, assuming I just had the alignment wrong and wanting directions to fix - they emailed back and said the arm jumped the track and damaged the arm
The positive thing is they will send me a replacement kit and I can send the bad ones back - and they said to call and they can walk me through the alignment on the phone (that is good customer service in my mind!). The mixed bag is that this must happen often enough that they know the symptoms immediately.
I've been looking at the setup trying to figure out how to DIY an alignment jig or gauge, but it's beyond my skill.
Has anyone had problems with alignment of the Star Fab after going doors-off?
