  2.

  1. Remove the outer tie rod end, jam nut, boot seal and clamps.
  2.  
  3. Use a wrench on the rack when either the left or right-hand tie rods are removed.
  4.  

Use a wrench on the rack teeth to avoid internal gear damage, as shown in the illustration in this section.

To install:

  1. Screw the tie rod end onto the steering rack and torque to 70 ft. lbs. (95 Nm).
  2.  
  3. Using a drift, stake the housing to the adapter flats on both sides.
  4.  
  5. Install the boot, clamps, jam nut and outer tie rod ends.
  6.  

Further overhaul of the rack and pinion assembly is not economical or practical because a complete remanufactured unit can be purchased at your local parts distributor for a fraction of the price of new.
