REMOVAL & INSTALLATION



1990-94 Vehicles

See Figures 1 and 2

  1. Disconnect the negative battery cable.
  2.  
  3. Raise and safely support vehicle.
  4.  
  5. Remove the wheel and tire assembly.
  6.  
  7. Remove the brake hose and tube bracket retainer bolt and bracket from the front strut. Do not pry the brake hose and tube clamp away when removing.
  8.  
  9. If equipped with ABS, disconnect the front speed sensor mounting clamp from the strut.
  10.  
  11. Support the lower arm using floor jack or equivalent. Remove the lower strut to knuckle bolts. Once the mounting bolts have been removed, jack up the lower arm. Use a piece of wire to attach the brake hose, tube and driveshaft to the knuckle and to help keep the weight off. These components are not to be pulled.
  12.  
  13. Before removing the top bolts, make matchmarks on the body and the strut insulator for proper reassembly. If this plate is installed improperly, the wheel alignment will be wrong. Remove the strut upper mounting bolts. Remove the strut assembly from the vehicle.

To install:
  1. Install the strut to the vehicle and install the top mounting bolts. Make sure the insulator is installed so the matchmarks made during disassembly are in alignment. Tighten the mounting bolts to 36 ft. lbs. (50 Nm).
  2.  
  3. Position the strut on the knuckle and install the mounting bolts. While holding the head of the lower mounting bolt, tighten the nuts to 80-101 ft. lbs. (110-140 Nm).
  4.  

Install the brake hose bracket and the ABS clamp.

  1. Install the wheel and tire assembly.
  2.  
  3. Carefully lower the vehicle.
  4.  
  5. Take the vehicle to a reputable repair shop to have the alignment checked and adjusted, if necessary.

  1. Once the spring is compressed, remove the locknut.
  2.  
  3. Remove the strut insulator, spring seat spring pad, bumper rubber and dust cover. Remove the coil spring.
  4.  
  5. Inspect all parts for rust, damage or corrosion and replace as required.
  6.  

To assemble:
  1. Install the spring onto the strut assembly.
  2.  
  3. Join the dust cover and the bump rubber and install onto the strut.
  4.  
  5. Assembly the spring upper seat tot he piston rod, fitting the notch in the rod to the shaped hole in the spring seat. Line up the holes in the strut assembly spring lower seat with the hole in the spring upper seat. This is made easier using a long piece of stock to act as a guide.
