My wife's 00 XJ has developed some new noises. We had the brakes done back in February, but have been having "squealing" issues ever since. Recently, when braking, a popping noise can be heard. It is definitely coming from the rear axle, but you have to listen for it. If the radio is turned up at all, the noise isn't audible. Also, having the windows down doesn't make it any more audible. Sounds almost like something is thumping the underside of the body as you slow down. Most notible at in-town speeds (40 mph or so) as you slow to a stop. The best way I can describe it is a "popopopop.pop.pop..pop...pop...pop.....pop.......pop.........pop". Starts out fast and slows down as I slow down. Pretty much dissapears around 10 mph or so. Either that or I just can't hear it anymore. And every once in a while it just doesn't happen at all.
Thoughts? Is this a brake issue (rear drums)? Is it something else? Thanks!
