I've been experiencing a high pitched metalic sounding, rythemic squeak, sort of cricket like if you will, for about a year now. The noise has been very difficult to track down as I can only hear it when driving along parked cars or a wall. My kids can hear it much better than me for some reason! It seems to make little difference turning one way or the other. It does seem to get briefly louder when driving through a small dip in the road. The brakes looked fine, and I cleaned and lubed the guide pins. The noise remained so I suspected it was early stages of wheel bearing failure and it would become more obvious with a little more time. In nearly a years time it has maybe gotten slightly louder if any at all. Took it to the dealer and they didn't find anything, couldn't hear the noise. Recently I drove the van slowly and had someone walk along side listening. They were convinced the sound was not coming from a wheel but was more towards the center of the front end. They could hear it pretty equally from each side. What I am wonder is do inner or outer CV joints ever squeek when going bad? I get no other vibrations or knocking sensations on bumps or turns. Would a bad bearing on a drive shaft output squeak like that but not leak any fluid? Should I just roll up the windows and not worry about it until something gets more obvious, hopefully not on our summer vacation in a couple of weeks? Ron
