Steering, Suspension and Front Drive Axle Boot and Seal Inspection

Inspect the front and the rear suspension and steering system for damaged, loose or missing parts, signs of wear or lack of lubrication. Inspect the power steering lines and hoses for proper hook-up, binding, leaks, cracks, etc. Clean and then inspect the drive axle boot seals for damage, tears or leakage. Service vehicle as necessary.

Exhaust System Inspection

Inspect the complete 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. Service vehicle as necessary.

Engine Cooling System Inspection

Inspect the hoses and replace them if they are cracked, swollen or deteriorated. Inspect all pipes, fittings and clamps; replace as needed. Clean the outside of the radiator and air conditioning condenser. To help ensure proper operation, a pressure test of the cooling system and pressure cap is recommended at least once a year.

Throttle System Inspection

Important: The accelerator and cruise control cables should not be lubricated under any condition. Throttle system components causing hesitation or sticking should be replaced.

Inspect the throttle system for interference or binding, and for damaged or missing parts. Replace parts as needed. Replace any components that have high effort or excessive wear. Do not lubricate accelerator or cruise control cables.

Brake System Inspection

Inspect the complete system.

Notice: A low brake fluid level can indicate worn disc brake pads which may need to be serviced. Also, if the brake system warning light stays on or comes on, something may be wrong with the brake system. If the anti-lock brake system warning light stays on or comes on, something may be wrong with the anti-lock brake system.

Inspect the brake lines and the hoses for proper hookup, binding, leaks, cracks, chafing, etc. Inspect the disc brake pads for wear and 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.
