TOE THE LINES

dirty fluid and en­sure the new lines and pump would only cy­cle fresh fluid. While re­plac­ing the lines them­selves is pretty straight­for­ward, chang­ing out the pump makes it a lit­tle tougher job. The pump will re­quire the en­gine fan to be re­moved and the belt-driven pul­ley to be re­moved with a spe­cial­ized puller that not ev­ery shade-tree me­chanic might have. Most au­to­mo­tive parts stores would have the puller and en­gine fan re­moval tool avail­able for rent if you think you’re skilled enough to do this job at home. Once the new power steer­ing pump was mounted in place and the pul­ley and en­gine ac­ces­sories were re­in­stalled, get­ting the new Driven Diesel lines in was a breeze. The multi-piece hose as­sem­blies make it easy to route ev­ery­thing where it needs to go, and the Cnc-bent tub­ing pieces al­lowed ev­ery­thing to fit per­fectly with no rub­bing or tight spots any­where around the frame and other steer­ing parts. New fluid was added to the sys­tem and the lines needed to be bled of any air be­fore get­ting the truck back out on the

 Af­ter re­mov­ing your power steer­ing cap to re­lieve any pres­sure you can re­move the re­turn hose from the hy­dro­boost and re­veal this large nip­ple that will be used to flush old fluid from the sys­tem. A 6-foot length of spare 5/16” fuel line hose can be...

  Once the flush was com­plete we could start re­mov­ing the fac­tory lines and the power steer­ing pump. The line threaded into the up­per pas­sen­ger side of the hy­dro­boost is first to be dis­con­nected with the other soon to fol­low. Be pre­pared with some...

With the en­gine run­ning and trans­mis­sion in Park you can slowly de­press the brake pedal un­til it feels firm, then hold. Turn the steer­ing wheel from 12 to 3 o’clock and hold again. Then re­lease the pedal slowly and bring the wheel back to 12 o’clock....

 While the truck didn’t show real symp­toms of a bad power steer­ing pump, the leak­ing lines were the main rea­son for the re­pair. At 168,000 miles with a larger-than-stock wheel/tire pack­age the pump couldn’t have much left in it, so a brand-new AC...

 To go along with the new pump and lines the com­plete power steer­ing and hy­dro­boost sys­tem will be flushed of old fluid and re-filled with new. The process is sim­ple by just re­mov­ing the rub­ber low­pres­sure re­turn hose shown here and pump­ing the fluid...
