If your trailing or suspension arms are worn, you will not be able to detect the wear unless you remove the arms - even then its not too obvious. My fronts were knocking badly but pulling / pushing / twisting did not show up the wear - only replacing them fixed the problem.....
Check by driving over a rough surface (I'm sure you have some in TX) with the engine turned off if possible. Be aware you won't have boosted brakes with the engine switched off, so pick a desertd road to try this - you don't have to drive fast to see if the suspension is the problem..
