Narrative:
While jacking aircraft X to complete tasks [a] and [B] during visit; noted that the nlg (nose landing gear) did not go to the centered position. I was able to move the nlg tires from right of center to left of center and back; but it had a lot of resistance to do it. It would not 'lock' to the centered position while fully extended on jacks.jacked a/C to complete another task and noted that the nlg did not center with the a/C on jacks.we removed the sliding member from the nlg and found that the fluid was clear and fresh. While removing the sliding unit it was noted that the 2 pins ([maintenance manual 32-20-04; fig 5; item 95; pn MS51838-107) were not installed. Disassembled lower sliding unit and found the 2 lock pins not installed. Did some research and found the nlg strut was repacked on [day X]. The a/C came into ZZZ on [day X+16] as a ron (remain overnight). We installed the pins and reinstalled the sliding member; serviced and ops check of the centering was good.the repack job cards step address installing these pins. Appears to be a failure to follow procedures.
