  Q: How to Service and Repair a Power Steering Gear Seal on Jeep Grand Cherokee?

  A:

  You should start servicing and repairing the steering by cleaning the pitman shaft and housing at the front with a wire brush. Use a wrench to rotate the stub shaft all the way from one stop to the other, counting the turns, then move it back again to the stop halfway, so the pitman shaft does not contact the housing. First, remove the bolts that hold on the pitman shaft cover, then remove the shaft assembly and finally the pitman shaft cover. Slide the serrated tip of the Puller 7794-A inside the housing and, using the Slide Hammer C-637, remove the pitman shaft dust seal, then ease out the oil seal retaining ring using snap ring pliers. Take the metal and plastic back up washers out of the housing before removing the oil seal with Puller 7794-A and Slide Hammer C-637. Pass Drop Driver 8277 up through the top bearing, line it up with the bottom one and mount Handle C-4171 to remove the lower bearing. Lift the gear to remove the upper bearing by using Driver 8277 and Handle C-4171. To mount the upper pitman shaft bearing, first insert the Driver 8294 into the housing and put the Handle C-4171 on top, driving the bearing until the bottom of the driver hits the flange upside down. Screw the lower pitman shaft bearing onto Driver 8294 and Handle C-4171, pushing it into the housing until its shoulder gets seated. First, put a layer of the special grease on the oil seal and the back up washers. Then, fit the oil seal into position with Driver 8294 and Handle C-4171, add the plastic washer so it rests down on the lip of the oil seal and finally add the metal back up washer. Attachment with snap ring pliers, brandish the dry seal with special grease and connect the seal with Driver 8294 and Handle C-4171. First, fit the new pitman shaft O-ring carefully into place, then push the shaft assembly into the housing, bolt the cover in place, tighten to 62 Nm (46 ft. lbs.) and do the over-center rotation torque adjustment.

  Q: How to Service and Repair a Power Steering Gear Seal on Jeep Wrangler?

  A:

  Before you do anything else, brush the pitman shaft and housing gently with a wire brush. Unscrew the preload adjuster nut and using a 12 point socket, turn the stub shaft from stop to stop and tally how many times you need to turn it. To center the stub shaft, rotate it from the stop portion of the total turns. Unscrew the side cover bolts and set them and the cover, gasket and pitman shaft aside as a group, making sure the shaft is correctly centered through the housing. Take off the pitman shaft from the side cover and use a seal pick to pull out the dust seal from the housing carefully so as not to harm the shaft bore. Pull out the snap ring pliers to remove the retaining ring, then use a seal pick to remove the washer and the oil seal. Remove the pitman shaft bearing from the housing by slipping a handle onto a bearing driver and driving it out. First, secure the pitman shaft bearing in the housing using a bearing driver and handle and afterward, cover both the oil seal and the washer with the new seal's grease, before installing the oil seal using driver and handle. After that, fit the back up washer and retainer ring with snap ring pliers, spread the special grease on the dust seal and set it in place using a driver and handle. Screw the pitman shaft into its place on the side cover as far as it will go. After that, place the preload adjuster nut, but do not tighten it until you have made an adjustment in Over-Center Torque. Set the gasket on the side cover, bend the tabs around and install the pitman shaft assembly and side cover into the housing. After that, install the side cover bolts, tighten them to 60 Nm (44 ft. lbs.) and perform the over-center rotation torque adjustment.
