Service of the coil spring requires the use of a coil spring compressor tool. It is required that 5 coils be captured within the jaws of the compressor tool.

  1. Disconnect the negative battery cable.
  2.  
  3. Raise and safely support vehicle. Do not support vehicle by placing supports under the suspension arms. The suspension arms must hang freely.
  4.  
  5. Remove the front wheel(s).
  6.  
  7. Remove the stabilizer bar attaching link at the strut assembly.
  8.  
  9. Loosen but do not remove the outer tie rod end to strut assembly steering arm attaching nut. Then remove the outer tie rod end from the steering arm using puller MB-990635 or equivalent.
  10.  
  11. If equipped with ABS, remove the speed sensor wire harness mounting bracket from the strut.
  12.  
  13. Remove the brake caliper assembly. Support the caliper assembly from the vehicle frame with a strong piece of wire. Do not allow the assembly to hang by the brake hose. Remove the front brake rotor disc.
  14.  

The strut assembly to steering knuckle bolts are serrated where they go through the strut and steering knuckle. Do not turn the bolts during removal. If bolts are turned, damage to the steering knuckle will result.

  1. The strut assembly to steering knuckle bolts must not be turned during strut removal. Hold the bolt head with a wrench and turn the nuts off the bolts.
  2.  
  3. Remove the three strut assembly upper mount to shock tower mounting nuts and washers. Remove the strut from the vehicle.
  4.  
  5. Securely mount the strut assembly into a vise or use the aide of a helper to hold the unit. Using paint, mark the strut unit, lower spring isolator, spring and upper strut mount for indexing of the parts at assembly.
  6.  
  7. Position the spring compressor tool onto the strut. Compress the coil spring until all load is off the upper strut mount assembly.
  8.  
  9. Install strut rod socket tool L-4558A on the strut shaft nut and a 10 mm socket on the end of the strut shaft to prevent it from turning. Remove the strut shaft nut.
  10.  
  11. Remove the upper mount assembly, jounce bumper and seat bearing and dust shield as an assembly.
  12.  
  13. Remove the coil spring and compressor as an assembly from the strut. Remove the lower spring isolator from the strut assembly lower spring seat.
  14.  
  15. Inspect all components for abnormal wear, oil leakage or failure. Replace parts as required.
  16.  

To install:
  1. Inspect the strut assembly for signs of leakage. Actual leakage will be a stream of fluid running down the side and dripping off the lower end of the strut. A slight amount of seepage between the strut rod and strut shaft seal is not unusual and does not affect performance of the strut assembly.
  2.  
  3. Install the lower spring isolator on the strut unit. Install the compressed coil spring onto the strut assembly aligning the paint marks made during removal.
  4.  
  5. Install the strut bearing into the bearing seat. Bearing must be installed into the seat with notches on the bearings facing down.
  6.  
  7. Lower the seat bearing and dust shield onto the strut and spring assembly. Align the paint marks made during removal.
  8.  
  9. Install jounce bumper and upper mount on the strut shaft aligning the paint marks.
  10.  
  11. Install the strut mount-to-shaft retainer nut. Inspect all alignment marks made during removal and align as required. While holding the strut shaft from turning with a 10 mm socket, tighten the strut shaft nut to 70 ft. lbs. (94 Nm).
  12.  
  13. Equally loosen the spring compressor tool until all tension is released. Remove the spring compressor tool.
  14.  
  15. Install the front strut into the shock tower and install the three upper mount nuts and washers. Tighten mounting nuts to 25 ft. lbs. (33 Nm).
  16.  
  17. Position the steering knuckle neck into the strut assembly. Install the strut assembly to steering knuckle bolts. Install the nuts onto the attaching bolts and tighten to 125 ft. lbs. (169 Nm). Do not turn the serrated bolt heads during installation. Turn only the nuts.
  18.  

The strut assembly to steering knuckle bolts are serrated (toothed) where they go through the strut and steering knuckle. Do not turn the bolts during removal. If bolts are turned, damage to the steering knuckle will result

  1. Install the brake rotor and the caliper assembly to the adapter. Tighten the caliper mounting bolts 14 ft. lbs. (19 Nm).
  2.  
  3. Install the front speed sensor cable routing bracket onto the front strut, if equipped.
  4.  
  5. Install the outer tie rod on steering arm and tighten attaching nut to 27 ft. lbs. (37 Nm).
  6.  
  7. Install the stabilizer link assembly onto the strut assembly and tighten the attaching nut to 70 ft. lbs. (95 Nm).
  8.  
  9. Install the front wheel and lug nuts. Tighten the lug nuts, in sequence, to 95-100 ft. lbs. (129-135 Nm).
  10.  
  11. Lower the vehicle to the ground. Connect the negative battery cable.
  12.
