Lower ball joints. Just before they fail they cause binding in the steering system which is why your pump is working so hard. On these trucks, LBJ failure is typically catastrophic. by design, the ball is being pulled out of the socket. Newer runners have the fail safe version. Aftermarket parts typically fail within a year so go with oem.

 

Thank you i'll try it
