Hi all,again, took the wife shopping yesterday and heard the usual slight scrape of the underside of the front bumper on the high kerb.(parking head on to the kerb). Thought nothing of it and just reversed a few inches and sat on the phone talking to a mate. Bloke taps on the window and tells me my bumper is on the floor and after a quick look he's right. I pushed it back on but it doesn't seem to "click" into place. How is it secured and how do I put it back on properly. Any help appreciated as always????
