Load Rear suspension noise(clunk) when going over bump even at slow speed.

What is your question?

Noise existed. Have replaced struts, and all moving joints. sway bar links not broken and feel good. After changing with new upper and lower arms and toe link had rear alighnment down. Three other technicans checked it out and can not find the noise either. Any suggestions? sway bar bushig look good. No noise on level roads. Upon quick start and then stop, noise is present on a lower lvolume level.
