GENERAL DESCRIPTION

Inertia principal axes system is incorporated into the engine mount system.

  1. The liquid-filled mount system have been adopted for engine mounting and transaxle mounting to improve ride feeling by optimizing the insulator.
  2. Installation of roll stopper in the upper area has reduced engine rolling. Furthermore, enlargement of insulator diameter has reduced idle vibration.

REMOVAL AND INSTALLATION

CAUTION*: Indicates parts which should be initially tightened, and then fully tightened after placing the vehicle horizontally and loading the full weight of the engine on the vehicle body.

>> A << ENGINE FRONT MOUNTING CUSHION STOPPER INSTALLATION

Arrow marks on the engine front mounting cushion stopper should face the shown direction.

Note. Disregard F and R stamped as a shared part.

Scheme 1103

Scheme 1103: >> A << ENGINE FRONT MOUNTING CUSHION STOPPER INSTALLATION

INSPECTION

  1. Check the engine front mounting insulator for cracks, separation or deformation.
  2. Check the engine front mounting cushion stopper for deformation.
CAUTION*: Indicates parts which should be initially tightened, and then fully tightened after placing the vehicle horizontally and loading the full weight of the engine on the vehicle body.

>> A << TRANSAXLE MOUNTING STOPPER INSTALLATION

Install the transaxle mounting stopper so that its arrow points upward.

Scheme 1105

Scheme 1105: >> A << TRANSAXLE MOUNTING STOPPER INSTALLATION
  1. Check the transaxle mounting insulator for cracks, separation or deformation.
  2. Check the transaxle mounting stopper for deformation.
CAUTION*: Indicates parts which should be initially tightened, and then fully tightened after placing the vehicle horizontally and loading the full weight of the engine on the vehicle body.

>> A << ENGINE FRONT ROLL STOPPER BRACKET INSTALLATION

Install the front roll stopper so that its hole points towards the front side of the vehicle.

Scheme 1107

Scheme 1107: >> A << ENGINE FRONT ROLL STOPPER BRACKET INSTALLATION

Check the engine roll stopper insulators for cracks, separation or deformation.

CAUTIONBefore removing the steering wheel and air bag module assembly, always refer to DRIVER-SIDE AIR BAG MODULE & CLOCKSPRING . Also, set the front wheels so that they are facing straight forward, and remove the ignition key. If you fail to do this, the SRS clock spring will be damaged, causing the SRS air bag to be inoperative and serious injury. * 1 : Indicates parts which should be initially tightened, and then fully tightened after placing the vehicle horizontally and loading the full weight of the engine on the vehicle body. * 2 : Indicates parts which should be temporarily tightened, and then fully tightened with the vehicle on the ground in the unladen condition. If the vehicle is equipped with the Brembo™ disc brake, during maintenance, take care not to contact the parts or tools to the caliper because the paint of caliper will be scratched.

  1. Install the special tool MB991897 (Scheme 1111)
  2. Turn the bolt and knob as necessary to make the jaws of special tool MB991897 parallel, tighten the bolt by hand and confirm that the jaws are still parallel. NOTE: When adjusting the jaws in parallel, make sure the knob is in the position shown in the figure.
  3. Tighten the bolt with a wrench to disconnect the tie rod end.

<< C >> FRONT AXLE NO. 1 CROSSMEMBER ASSEMBLY REMOVAL

Retain the crossmember with a transmission jack, and then remove the crossmember mounting bolt.
