i have a 1998 daewoo gc25 s-3 , when i bought it it had power steering , but seemed like it had air in the system because it would steer , pretty good then , steering got harder to turn , i noticed the hydraulic tank on side of truck the tank was 190 degrees , so i opened the hydraulic tank and the filters seemed clean , someone told me there must be a blockage somewhere, so i took to forklift to repair shop they put in a new orbital , still no steering , so they rebuilt the hydraulic master cylinder , still no steering , then they put new hydaulic pump on the truck , still no steering , they checked pressure at the orbital but only went up to about 5 psi , then they took the gauge off and started it fluid shot out , but no pressure , anyone else ever have this problem on this model daewoo , we dont know what else to try to fix the steering on this unit , if you lift the back of the forklift up the steering can be turned side to side , by moving the wheels back and forth by hand, any help would be greatly appreciated thank you , serial numbe is 95-00658
