Pulled everything back apart yesterday. Looked the suspension over thoroughly, all looks normal. Wheel bearings had the slightest amount of vertical play, so I pulled the axle shafts and the bearings. They looked quite good, actually - I bet someone did these in the last 20,000 miles (I've put about 12,000 miles on the truck over the last decade). But I figured, why not replace them since I had it apart anyway. While ordering bearings and seals I went ahead and ordered new drums as well. Not that expensive, the old ones are getting thin, and I'm ready to stop taking things apart repeatedly

Guess we'll see what the results are once it's all back together next weekend. Thanks to everyone who's tried to help.
