So recently some funky crack pop and clang noises have been coming from the rear of my car. Replacing u-joints today I nearly positive thats the crack/pop noise. As for the clang, it seems to be coming from the rear itself. If I grab the rear tire(either one) and push/pull on it in and out i get a clanging noise. The noise sounds like its the drum or something but everything looks okay in there. The rear does have a little play from side to side but I'm told thats normal. I've had a friend look at this noise too, he thinks its nothing to worry about. So I've come here for some more advice on what you guys think it may be and if it is a problem or an annoyance?
