Had a new refurbished axle from IM axles put on over a month ago now, it was pre lowered 40mm by them. Day I got it done it sat perfect, just how I wanted it to sit:

However over the past few weeks the rear has developed a arch gap for some reason, it definitely isn't down 40mm anymore. Picture from tonight:

Any ideas why?
