Lubrication System
The engine lubrication system operates as follows:
•Oil is drawn into the oil pump through the oil pump strainer tube in the sump of the oil pan.
• Oil is pumped through the oil filter on the cylinder block.
• Oil enters the main oil gallery where it is distributed to the crankshaft main journals and to the cylinder head.
• From the main journals, the oil is routed through cross-drilled passages in the crankshaft to lubricate the con-
necting rod bearings. Controlled leakage through the crankshaft main bearings and connecting rod bearings is
slung radially outward to cool and lubricate the cylinder walls as well as the entire connecting rod, piston and
piston ring assembly.
• The engine lubrication system is a full-flow filtration, pressure feed type. The oil pump body is mounted to the
engine block. The pump inner rotor is driven by the crankshaft.

The strut assembly cushions the ride of the vehicle, controlling vibration, jounce and rebound of the suspension. The
coil spring controls ride quality and maintains proper ride height. The spring isolators isolate the coil spring at the top
and bottom from coming into metal-to-metal contact with the upper mounting seat and the strut. The strut dampens
jounce and rebound motions of the coil spring and suspension.
Diagnosis & Testing
Before removing the front strut, perform the following to test the front strut functionality:
•Adjust the tire pressure to all tires to proper specifications.
• Push and shake the front of the vehicle three or four times with identical force every time
• During the pushing and recoiling, the resistance and recoil times of the vehicle should be equal.
• If the strut (shock absorber) functions properly, the vehicle will recoil several times and then stop recoiling after
the pushing force is removed.
Removal & Installation
1. Raise and support the vehicle.
2. Remove the wheel mounting nuts and the wheel assembly.
(Tighten: Wheel mounting nuts to 110 N·m)
3. Disconnect the brake fluid hose clamp (1) from the brake fluid hose bracket on the front strut.
4. Remove the brake fluid hose from the bracket.
5. Remove the wheel speed sensor wire.
6. Remove the nut (1) from the front stabilizer bar link bracket on the front strut.
(Tighten: Front stabilizer bar link bracket nut to
48 ± 6 N·m)

Description
Vehicle wheel alignment is the positioning of all interrelated front and rear suspension angles. These angles affect the
handling and steering of the vehicle when it is in motion. Proper wheel alignment is essential for efficient steering,
good directional stability, and proper tire wear.
The method of checking a vehicle’s front and rear wheel alignment varies depending on the manufacturer and type
of equipment used. The manufacturer’s instructions should always be followed to ensure accuracy of the alignment.
On this vehicle, the suspension angles that can be adjusted are as follows:
Front Axle
•Camber
• Caster
• Toe-in
Rear Axle
• Camber
• Toe-in
Check the wheel alignment and make all wheel alignment adjustments with the vehicle standing at its proper curb
height specification. Curb height is the normal riding height of the vehicle. It is measured from a certain point on the
vehicle to the ground or a designated area while the vehicle is sitting on a flat, level surface.
Operation
Curb Height Measurement
The wheel alignment is to be checked and all alignment adjustments made with the vehicle at its required curb height
specification.
• Vehicle height is to be checked with the vehicle on a flat, level surface, preferably a vehicle alignment rack.
• The tires are to be inflated to the recommended pressure.
• All tires are to be the same size as standard equipment.
• Vehicle height is checked with the fuel tank full of fuel, and no passenger or luggage compartment load.
• Vehicle height is not adjustable.
• If the measurement is not within specifications, inspect the vehicle for bent or weak suspension components.
• Compare the parts tag on the suspect coil spring(s) to the parts book and the vehicle sales code, checking for
a match.
• Once removed from the vehicle, compare the coil spring height to a new or known good coil spring. The
heights should vary if the suspect spring is weak.
NOTE :
Prior to reading the curb height measurement, the front and rear of the vehicle must be jounced to settle the sus-
pension. Induce jounce by pushing down on the center of the bumper (fascia), using care not to damage the vehicle,
moving the vehicle up and down, gradually increasing the suspension travel with each stroke. Release the bumper at
the bottom of each stroke, repeating this action several times. Perform this to both front and rear suspensions an
equal number of times.
Pre-Wheel Alignment Inspection
Before any attempt is made to change or correct the wheel alignment, the following inspection and necessary cor-
rections must be made to the vehicle to ensure proper alignment. 1. Verify the fuel tank is full of fuel. If the fuel tank is not full, the reduction in weight will affect the curb height of the vehicle and the alignment specifications.
2. The passenger and luggage compartments of the vehicle should be free of any load that is not factory equip- ment.

must be the same size and in good condition with
approximately the same tread wear.
4. Check the front tire and wheel assemblies for excessive radial runout.
5. Inspect all suspension component fasteners for looseness and proper torque.
6. Inspect all ball joints and all steering linkage for looseness and any sign of wear or damage.
7. Inspect the rubber bushings on all the suspension components for signs of wear or deterioration. If any bushings show signs of wear or deterioration, they should be replaced prior to aligning the vehicle.
8. Check vehicle curb height.
Wheel Alignment Setup
1. Position the vehicle on an alignment rack.
2. Install all required alignment equipment on the vehicle, per the alignment equipment manufacturer’s instructions. On this vehicle, a four-wheel alignment is recommended.
3. Read the vehicle’s current front and rear alignment settings. Compare the vehicle’s current alignment settings to the vehicle specifications for camber, caster and toe-in.
NOTE :
Prior to reading the vehicle’s alignment readouts, the front and rear of vehicle should be jounced. Induce jounce (rear
first, then front) by grasping the center of the bumper and jouncing each end of the vehicle an equal number of
times. The bumper should always be released when vehicle is at the bottom of the jounce cycle.
