My left rear passenger caliper was leaking brake fluid -- so we replaced the caliper and put new pads on in the process.

A few hours before doing this, it became obvious that both front barrings were shot -- so we spent the next three weeks replacing those. Yes. It took three weeks to remove one. Broke four pullers and a 7 ton gear puller in the process. With a propane torch. And super-duper penetrating spray. And a five pound hammer. And cold chisels. Three weeks. 3-5 hours every day. The amount of rust was absurd. Ab. Surd.

When we finished the front hub we took the Blazer out for a quick test drive to make sure everything was in good shape.

In drive and reverse, there is a constant ping/clunk noise that is coming from the back tire that we put the caliper/brakes on. The noise picks up in frequency when you accelerate and sounds like the hub hitting ... something. I'm not sure what is being hit -- but part of the noise sounds like the hub. I could be way off on that; but it's a very distinct and loud thud.

The idea we have currently is:
Maybe the barrings in the back are bad, as well -- and with the previous caliper / worn brakes, there was enough room for the small amount of play to not be an issue; but with full brakes and a new caliper there is no room and it is hitting ... something. I would really like this to not be the issue -- but we're kind of at a loss for what else it could be.

If anybody has any idea on this, I'd be greatly appreciative. I've been without a car for three weeks (FT college; FT work; bumming rides from people that I'm going to owe for years to come after I'm done repaying a Life-Debt to dad for the barrings) and last night was the most excited I've been this year. If it's the back barrings, it's going to the shop Monday -- but if anyone has any suggestions for troubleshooting and locating other potential causes, that would be wonderful and I will owe you an alcoholic beverage of your choice in the event you ever enter East TN.
