Junk Removal Truck Maintenance Schedule

Engine oil and filter change — $80–$150 for diesel (15W-40 or manufacturer spec), $50–$80 for gas. Use OEM-spec filters, never economy brands on a work truck.

Tire pressure check on all six tires plus the spare — set to door-jamb PSI cold, not warm. One PSI low across six tires wastes $200/year in fuel.

Brake visual inspection: measure pad thickness with a gauge, check rotors for scoring, inspect lines for chafing. Junk trucks eat front pads 30% faster than highway vehicles.

All fluid levels topped: coolant (check concentration with a refractometer), brake fluid, power steering, transmission dipstick, and windshield washer. Low coolant in summer kills head gaskets.

Full lighting check: headlights high and low, brake lights, turn signals, hazards, reverse lights, and DOT-required marker lights. A burned-out marker light is a $150 roadside citation.

Lug nut torque check on all wheels — re-torque to spec after any tire service. A loose wheel at highway speed is a catastrophic event that ends careers.

Inspect hydraulic dump or lift-gate cylinders for weeping seals. A slow leak becomes a failed lift mid-job within 60 days if ignored.

Tire rotation in an X-pattern for dual-rear-wheel trucks. Extends tire life by 25–40%, saving $400–$800 per set over the tire's lifetime. Mark tires with chalk to verify rotation was actually done.

Engine air filter replacement — $20–$50. A clogged air filter reduces fuel economy by 6–10% on diesel engines, costing $40–$60/month in wasted fuel at current diesel prices.

Cabin air filter replacement — $15–$30. Your crew breathes dust from demo debris and dump facilities all day. A clean cabin filter is a health and retention issue, not just comfort.

Battery load test and terminal cleaning with a wire brush and dielectric grease. A weak battery that cranks slowly in October will leave your crew stranded in December. Replace proactively at 3 years.

Full suspension inspection: shocks, struts, leaf springs, U-bolts, bushings, and sway bar links. Junk trucks running 8,000–14,000 lb loads on rough dump roads wear suspension components at 2× the normal rate.

Lift gate or ramp mechanical inspection: lubricate hinges, check cable tension, inspect rollers and latches. A stuck lift gate at a customer's house costs you the job and the review.

Exhaust system inspection for leaks — especially at manifold gaskets and flex pipes. Carbon monoxide intrusion into the cab is a silent killer. Check for soot stains at every joint.

U-joint and driveshaft inspection — feel for play by hand. A failed U-joint at speed drops the driveshaft onto pavement, vaults the truck, and totals the vehicle. $40 part, $50,000 consequence.

Brake pad replacement when worn to 3mm or less. Budget $400–$900 per axle including pads and labor. Junk trucks average pad replacement every 25,000–35,000 miles — much shorter than the 50,000 miles your shop might quote for a normal truck.

Transmission fluid and filter change — $200–$400. Critical for longevity of the Allison or Ford TorqShift. A transmission replacement runs $4,000–$8,000 installed; this service is cheap insurance against that bill.

Coolant flush and replacement with OEM-spec coolant — $120–$200. Old coolant loses its corrosion inhibitors and starts eating your water pump, radiator, and heater core from inside. Never mix coolant types.

Fuel filter replacement — $30–$80 for the part, critical on diesel engines. A clogged fuel filter starves the injectors, causes rough idle, and can damage the high-pressure fuel pump ($1,800–$3,200 replacement).

Drive belt inspection and replacement if cracked, glazed, or stretched. A snapped serpentine belt kills your power steering, alternator, and AC simultaneously, stranding the truck mid-route. $25 belt, $500 tow.

DOT annual inspection — legally required for vehicles over 10,001 lbs GVWR. Budget $50–$150 at a certified inspection station. Schedule 30 days before expiration so you have time to fix any failed items.

Wheel bearing repack or inspection — especially on trailers if you run one. A seized wheel bearing at highway speed can cause a wheel-off event. Listen for humming or grinding on test drives after service.

Fuel system cleaning and injector service on diesel engines — $150–$250. Removes carbon deposits that reduce fuel economy and power output. Especially important if you run ULSD fuel in older engines.

Full tire replacement — budget $800–$2,000 for a set of six commercial tires (LT or medium-duty). Don't mix tire brands or tread depths on the same axle. Run the same tire across all six positions for even wear.

Brake rotor replacement if thickness is below manufacturer minimum spec or if rotors are scored or heat-cracked. Budget $150–$300 per rotor installed, $600–$1,200 for a full set of four.

Spark plug replacement on gas engines — $150–$250 for parts and labor on a V8. Misfires from worn plugs waste fuel, foul catalytic converters ($800–$1,500 replacement), and cause failed emissions inspections.

Full electrical system diagnostic with a scan tool — check for stored codes, parasitic draws, alternator output under load, and wiring harness integrity. Intermittent electrical issues cause 20% of all unplanned downtime.

Box body inspection: probe the floor for rust-through with an awl, check wall panel rivets, test door mechanisms, inspect the roof for leaks. A rusted floor failure with a loaded truck is a safety catastrophe and a DOT violation.

Power steering system flush and inspection — $100–$150. Old fluid breaks down and damages the pump and rack. A power steering failure in a 14,000 lb loaded truck is a dangerous driving emergency.

Differential fluid change — front and rear — $80–$120 per axle. Neglected differential fluid causes bearing wear and gear whine. A differential rebuild runs $1,500–$3,000.

Complete frame inspection for cracks, rust, and weld integrity. Have a shop put the truck on a lift and visually inspect every frame rail, crossmember, and body mount. Frame damage is often a terminal diagnosis.
