If it is just the bushing that normally wears, has anyone replace it with a poly bushing?

Clunking sound is only heard over uneven surfaces not under braking.

Is there a way to test the bushing such as placing a pry bar somewhere and note any movement?

Edit:

Anyone use this kit to repair a compression rod instead of buying a new rod?

Poly bushings can also be used, actually just replaced all the rear suspension, subframe and differentail bushings getting ready to install poly bushings on front suspension and steering rack.

Part below is what you will need
