Yes and no. It will probably come back soon enough. You need to trouble-shoot to find out what's wrong. The sound you are hearing will probably come back if you put stress on your rear suspension components (if that's what is causing it.) You can start trying to isolate your issue by finding some sloped surface and creeping onto it and off of it with the rear end. Drive slowly to see if you can hear the pop. If you can, then get a friend out there to look underneath the vehicle while you do this... obviously, don't let your friend actually get under the vehicle to inspect unless you know exactly what you are doing. I've been under one or two vehicles inspecting to help out my friends but I really, really trust their ability to avoid running over my arse!
