On a drive home from work I started to get a growl, then a squeak, and then a clunk! It took an entire weekend on jackstands, but it was really a lot of things in one. One of the spindle retaining bolts had managed to strip and back out, the wheel bearings (new) needed to be tightened (which is normal), and the caliper sliders needed more grease and an adjustment (they are really not a very good design). I replaced the bolt and re-torqued everything, then did all of the adjustments. I also messed with the adjustable master cylinder rod to adjust the brake pressure and bled the thing again.
