  1. Raise and support the front of the vehicle on jackstands.
  2.  
  3. Remove the wheels to provide access (and light).
  4.  
  5. Disconnect the stabilizer bar link nuts, then slowly pull the bolts down, from underneath the lower control arms. As the bolts are removed, the retainers, insulators and link spacer will be freed from the bolt. BE SURE to note the locations for each of these components and keep them in order. It is probably best to install them in order over the bolt and put the nut on the end to keep any part from being lost.
  6.  
  7. Remove the stabilizer bar-to-frame clamps.
  8.  
  9. Remove the stabilizer bar from the vehicle. If necessary, remove the insulators from the shaft.
  10.  

To install:
  1. If removed, install the insulators on the shaft. The slit on the insulator should be positioned toward the front of the vehicle.
  2.  
  3. Install the stabilizer shaft and brackets to the van, making sure the shaft is mounted with the identification on the right side of the vehicle. Install the shaft offset in the downward position and make sure the insulators are positioned squarely in the clamps.
  4.  
  5. Loosely install the stabilizer bar-to-frame clamps in order to hold the bar.
  6.  
  7. Install the stabilizer links through the control arms, positioning the necessary components (insulators, washers, retainers and the link spacer) as it is inserted. Connect the links to the ends of the bar, installing the washer and nut.
  8.  
  9. Tighten the stabilizer bar link-to-lower control arm bolts to 13 ft. lbs. (18 Nm) and the stabilizer retainer-to-frame bolts to 22 ft. lbs. (29 Nm) for 1985-87 vehicles or to 27 ft. lbs. (36 Nm) for 1988-96 vehicles.
