Volvo 780 making popping noise when we turn hard right or left

He has thought about the cab mounts. I don't know if he has checked the power steering box. I do know
he has been under the truck shaking and trying to move everything to make sure nothing is loose and fixing to break loose.

 

Truck is in shop. We took it today and told them to find out what's popping. We told them everything that we have had done on the truck and I just pray they can find what's the matter.

Truck is in shop and hopefully this will fix our popping noise.

 

Thanks for all that replied..

 

So far so good. Truck is no longer popping. They showed us the the broken crossmember on top of transmission.
It is riding much better also due to the whole spring assembly under the front end..and I checked everything was new..not just the springs. . That's me being happy and not fearing I'm not going in the ditch any minute.
