Perform the following inspections and services at least twice a year-for instance, each spring and fall. Ensure any necessary repairs are completed immediately.
Steering, Suspension and Front Drive Axle Boot Seal Inspection
Inspect the front and the rear suspension for the following:
| • | Signs of wear or lack of lubrication |
Inspect the power steering lines and the hoses for the following:
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the body near the exhaust system. Look for broken, damaged, missing or out-of-position parts as well as open seams, holes, loose connections, or other conditions which could cause a heat build-up in the floor pan or could let exhaust fumes into the vehicle.
Fuel System Inspection
Inspect the complete fuel system for damage or leaks.
Engine Cooling System Inspection
Inspect the hoses and replace if they are cracked, swollen or deteriorated.
Inspect all pipes, fittings and clamps; replace as needed.
Important: The radiator and A/C condenser should be kept clean for proper system performance. Cleaning is recommended at least once a year.
Inspect the front surface of the radiator and A/C condenser. Insects, leaves, debris, etc. can affect the performance of the radiator and A/C condenser.
If the front surface of either or both of these components is found to be in need of cleaning, the unwanted material can be removed by performing the following:
| • | Ensure that the engine is off and cool. |
| • | Blow compressed air through the radiator from the rear surface of the radiator toward the front of the vehicle. |
| • | If compressed air is not available, use a water hose to force water through the radiator from the rear surface of the radiator toward the front of the vehicle. |
To help ensure proper cooling system pressure performance, a pressure test of the cooling system and pressure cap is recommended at least once a year.
Throttle System Inspection
Notice: Do NOT lubricate accelerator or cruise control cables. Lubrication
will destroy the protective coating on these cables.
Inspect for the following and replace as needed:
| • | Missing parts such as retainers or clips. |
| • | Interference of linkage or cable conduit to critical components such as fuel lines, brake pipes or harness leads. |
| • | Proximity of cable to exhaust system and other heat sources (check for melting and/or discoloration). |
| • | Cable kinking, avoid sharp bends of the cables. |
| • | Clearance of throttle system moving parts throughout their travel from other stationary components. |
| • | Damage of components due to cable kinking, severe abrasion or misalignment. |
All-Wheel Drive Inspection
Inspect the transfer case-power transfer unit and carrier assembly-differentials, rear drive module every 12 months or at engine oil change intervals. Check front axle and transfer case and add lubricant when necessary. A fluid loss could indicate a problem. Check and have it repaired, if needed. Check vent hose at transfer case for kinks and proper installation.
Brake System Inspection
Inspect the complete system.
Inspect the brake lines and the hoses for the following:
Inspect the disc brake pads for wear. Inspect the rotors for surface condition. Inspect other brake parts, including the calipers, the parking brake, etc.
The brakes may need to be inspected more often if driving habits or conditions result in frequent braking.
