I'm thinkin' it's a bad wheel bearing, but lets see what the general opinion is. Just finished installing my D44 into my s10 blazer. I took it for a test drive around the block and after a few hundred yards it starts making a "popping" noise from the wheel. I can kinda feel it in the steering wheel (I have a rathar loose steering setup) and feel it in the floorboards decently. On the way back home it slowly gets worse and starts squeeling a bit. Also it is worse when braking or turning. There ya go. I need new wheel bearings or what?
