So I just replaced my front wheel bearings (which needed replacing badly) and new pads/rotors/drum pads, while searching for an elusive squeal. Definitely drivetrain as I can coast in neutral downhill with the engine off and hear the squeal. Not pads as I can apply brakes and the squeal is still pronounced (either by brake pedal or using parking brake to slow). I noticed the front wheels are MUCH tighter now with no vertical play. Checking the rear wheels I have a fair amount of vertical play and no horizontal play so am I correct in thinking this is my next task? Other than the front axle bearings (CV?) I'm out of ideas.

Squeal starts when I reach about 15mph. I can get it to stop briefly on a tight turn to the left for some odd reason.

211K+ miles, I'm in for the long haul with this rig (wife says she'll bury me in it!) Thanks in advance-
