DESCRIPTION AND OPERATION

Front Suspension

The front suspension consists of the following components:

  • Wheel bearing and wheel hubs
  • Wheel studs
  • Lower arms
  • Stabilizer bar
  • Stabilizer bar links
  • Struts
  • Springs
  • Wheel knuckles

The front suspension utilizes a MacPherson strut system.

This suspension system incorporates a strut assembly that takes the place of the upper arm and ball joint. The strut carries out the function of a shock absorber and is encompassed by a coil spring. The strut and spring assembly supports the weight of the vehicle and is also the pivot point for the steering knuckle. This system uses a lower control arm and ball joint for the lower (unloaded) pivot point of the steering knuckle.

Wheel Bearing and Wheel Hub

General Equipment

  • Front wheel hub remover

Removal

NOTICE: Suspension fasteners are critical parts because they affect performance of vital components and systems and their failure may result in major service expense. New parts must be installed with the same part numbers or equivalent part, if replacement is necessary. Do not use a replacement part of lesser quality or substitute design. Torque values must be used as specified during reassembly to make sure of correct retention of these parts.

NOTE: Removal steps in this procedure may contain installation details.

  1. Remove the wheel and tire. Refer to Section 204-04.
  2. NOTE: Apply the brake to keep the halfshaft from rotating.

    NOTE: Do not discard the wheel hub nut at this time.

  3. Remove the brake disc. Refer to Section 206-03.
  4. NOTE: Push the halfshaft into the wheel hub to gain access for the removal of the wheel bearing and wheel hub bolts.

    General equipment: Front wheel hub remover

  5. NOTICE: The wheel knuckle bore must be clean enough to allow the wheel bearing and wheel hub to seat completely by hand. Do not press or draw the wheel hub and bearing into place or damage to the bearing may occur.

    NOTICE: Make sure the wheel hub-to-wheel knuckle mating surfaces are clean and free of any adhesive. Failure to clean the adhesive from both surfaces may cause bearing damage.

Installation

  1. Finger tight at this stage.
  2. NOTE: Push the halfshaft into the wheel hub to gain access for tightening the wheel bearing and wheel hub bolts.
    • Tighten the new bolts to 133 N·m in the sequence shown.
  3. Install the brake disc. Refer to Section 206-03.
  4. NOTICE: Do not tighten the front wheel hub nut with the vehicle on the ground. The nut must be tightened to specification before the vehicle is lowered onto the wheels. Wheel bearing damage will occur if the wheel bearing is loaded with the weight of the vehicle applied.

    NOTE: Apply the brake to keep the halfshaft from rotating and use the previously removed wheel hub nut, seat the halfshaft.

    • Tighten the previously removed nut to 350 N·m
  5. NOTICE: The wheel hub nut contains a one time locking chemical that is activated by the heat created when it is tightened. Install and tighten the new wheel hub nut to specification within 5 minutes of starting it on the threads. Always install a new wheel hub nut after loosening or when not tightened within the specified time or damage to the components can occur.
    • Tighten the new nut to 350 N·m
  6. Install the wheel and tire. Refer to Section 204-04.

WARNING: Do not apply heat or flame to the shock absorber or strut tube. The shock absorber and strut tube are gas pressurized and could explode if heated. Failure to follow this instruction may result in serious personal injury.

WARNING: Keep all body parts clear of shock absorbers or strut rods. Shock absorbers or struts can extend unassisted. Failure to follow this instruction may result in serious personal injury.

NOTICE: Suspension fasteners are critical parts because they affect performance of vital components and systems and their failure may result in major service expense. New parts must be installed with the same part numbers or equivalent part, if replacement is necessary. Do not use a replacement part of lesser quality or substitute design. Torque values must be used as specified during reassembly to make sure of correct retention of these parts.

NOTICE: When installing a suitable spring compressor, use care not to damage the spring coating.

  1. Remove the strut and spring assembly. For additional information, refer to Strut and Spring Assembly in this section.
  2. WARNING: Coil springs and strut assemblies are compressed under extreme load. Always use a spring compressor for disassembly. Follow procedure instructions carefully and make sure the spring compressor has the correct spring plates or adapters. Failure to follow these instructions may result in serious personal injury.

    NOTE: Use the hex-holding feature to prevent the shock absorber rod from turning while removing or installing the strut rod nut.

    Using a suitable spring compressor, slightly compress the spring to remove initial tension. Using the hex-holding feature to hold the strut rod, loosen the strut rod nut. Continue to compress the spring until tension is relieved.
  3. Using the hex-holding feature to hold the strut rod, remove and discard the strut rod nut.
    • To install, tighten the new nut to 133 N·m.
  4. Inspect the upper strut mount and seat-bearing assembly. The spring insulator should not be cracked, torn or distorted. The strut bearing should turn freely without grinding. Install a new upper strut mount, if necessary.
  5. Decompress and remove the spring. Remove the dust boot and jounce bumper.
    • To maintain wheel camber:
      • position the notch and arrow on the upper strut mount outboard opposite the center of the mounting flanges on the strut.
    • To adjust camber +0.5 degrees:
      • position the notch and arrow on the upper strut mount inboard aligned with the center of the mounting flanges on the strut.
  6. NOTICE: Do not overtighten the strut rod nut. Damage to the nut or strut rod may occur.

    NOTE: Make sure the spring is correctly seated in both spring seats.

    NOTE: During assembly, apply the specified silicone brake grease to the strut rod and the top and sides of the outermost part of the dust boot.

    To assemble, reverse the disassembly procedure.
