REMOVAL & INSTALLATION



2wd Vehicles

See Figures 1 and 2

  1. Raise and support the front of the vehicle safely using jackstands.
  2.  
  3. If necessary, remove the front wheels for additional access.
  4.  
  5. Loosen the nut from the top of one of the link bolts, then remove the retainer and grommet so the stabilizer may be separated from the link bolt. If necessary, remove the link bolt, washers and grommets, but make sure all components remain in order on the link bolt once it is removed. This should be done in order to ease installation.

  1. Loosen the nut from the top of the other link bolt and separate it from the stabilizer in the same fashion. If the link bolt and components are completely removed, be sure to tag or arrange everything to assure installation on the same side.
  2.  
  3. Loosen and remove the bolts retaining the stabilizer brackets to the frame, then remove the stabilizer bar from the vehicle.
  4.  
  5. If necessary, remove the rubber bushings (insulators).
  6.  

To install:
  1. If removed, install the rubber bushings to the stabilizer bar, making sure they are positioned with the slits facing toward the front of the vehicle.
  2.  
  3. Position the stabilizer shaft, then install the brackets over the bushings to retain the shaft. Tighten the bracket bolts to 24 ft. lbs. (4 Nm).
  4.  
  5. Install the link bolts making sure the positioning of the grommets, retainers and washers is correct. If necessary, refer to the illustration for classification. But keep in mind the grommets are normally surrounded by washers/retainers or components (control arm or stabilizer).
  6.  
  7. Install the upper grommet, retainer and nut to the top of each link bolt, then tighten to 13 ft. lbs. (17 Nm).
  8.  
  9. If removed, install the front wheels.
  10.  
  11. Remove the jackstands and carefully lower the truck.

Installation of the stabilizer bar requires that the torsion bar be unloaded using a special unloader tool that is also used during tension bar removal. Do not attempt this procedure without the unloader. For details on the unloader and its use, please refer to the tension bar procedure found earlier in this section.
