My window cracks

A few weeks ago i posted up this thread and got great help off all the guys

now that i have fixed the problem by having my windscreen resealed it makes a cracking sound as i go over bumps in the roads, being lowered on 17's with low profiles that is a lot, but it does it even more when the heater is on...
i dont want to call the company and ask them if its normal coz they will just tell me yes so they dont have to come out (warranty on workmanship)...
to me it sounds like expansion cracks, i thought it might just be the windscreen setling in or something...does anyone know and can shed some light on the matter it would be good to hear and get some help

There may be movement in the glass and its moving around?


I would drive back to them and ask them to come for a drive around the block.
Then see what they have to say about it.

does anyone else know what it could be...has anyone had this happen to them before, or does anyone fit windscreens and could give me a profesional opinion
