Ball Joints: How to Tell if they are bad ?
 

I'm getting some 'thunks' from my 2001 Civic EX front suspension, usually
when shifting between 1-2 and 2-3 , and also when the front tires hit an
obstacle that causes a front-to-back impact vs. and up and down. No problems
when driving daily at speed on the interstate. Struts are new Tokico blues,
as are the rear shocks.
Could it be bad ball joints ?
