[TR] Knock in rear brakes?

[Dave1massey at cs.com]

I had what a noise that I was convinced was a rear wheel bearing.  When I 
crawled under the car to pull the hub off I found it was the U-joint on the 
half shaft.  What luck.  

U-joint problems can be obvious but sometimes they can be misleading.
