1985 TOYOTA PICKUP

Typical onset: 150,000-250,000 mi

Symptoms: Rattling noise on cold start that quiets after warm-up, Metallic slapping from front of engine under acceleration, Check engine light (22RE) with timing-related codes, Loss of power, rough idle as wear progresses

Fix: Replace timing chain, guides, tensioner, and rails as a complete kit. Requires front cover removal, oil pan drop recommended for debris cleanup. 6-8 labor hours for experienced tech, 10+ for DIY first-timer. Critical: do NOT ignore the rattle—jumped timing destroys valves.

Estimated cost: $800-1,400

Typical onset: 200,000+ mi

Symptoms: White smoke from exhaust on startup, Coolant loss with no visible leaks, Overheating under load, Milky oil on dipstick or oil cap, External coolant seepage at head/block junction

Fix: Common failure between cylinders 2-3 or externally. Head removal, resurface (usually warped .003-.008"), new gasket set, timing components while apart. 12-16 hours labor. Many shops recommend valve job and seals at this mileage. Head can crack if severely overheated.

Estimated cost: $1,800-2,800

Typical onset: 100,000-180,000 mi

Symptoms: Clicking or popping when turning, especially under throttle, Vibration during acceleration in 4WD, Grease splattered inside wheel well, Clunking from front axle

Fix: The inner birfield (CV joint) on the front axles wears out, especially right side. Rebuild kits available but most techs replace the entire axle assembly. 2-3 hours per side. OEM quality crucial—cheap aftermarket fails fast.

Estimated cost: $400-700 per side

Symptoms: Hard starting when cold, requires pumping throttle, Rough idle, intermittent stalling, Hesitation on acceleration, Black smoke, poor fuel economy, High idle that won't come down

Fix: The Aisan carb needs periodic rebuild or replacement. Choke mechanism, accelerator pump, and vacuum passages clog. Rebuild kits $40-80, takes 3-4 hours if you know carbs. Most owners convert to Weber 32/36 or 38/38 ($350-450) for 2-3 hours labor—fixes it permanently.

Estimated cost: $300-600

Symptoms: Visible surface rust progressing to scale and holes, Rust-through behind cab corners, above rear axle, Structural weakness at leaf spring mounts, crossmembers, Fuel tank strap area rust-through

Fix: Regional problem—severe in salt states, minimal in Southwest. Inspect before purchase: if rear crossmember or spring hangers are compromised, repair involves cutting and plating. 8-20+ hours depending on extent. Some frames are too far gone to save economically.

Estimated cost: $1,500-5,000+

Typical onset: 120,000-200,000 mi

Symptoms: Grinding or humming from front wheels that changes with speed, Wheel wobble, looseness when jacked up, ABS-like pulsing through steering (though no ABS on '85), Uneven tire wear on inner or outer edge

Fix: The manual-locking hub design requires hub disassembly to service bearings. Clean, repack, or replace bearings and races. 2-3 hours per side. Must be torqued and adjusted correctly or bearing life is cut in half. Aftermarket hubs are hit-or-miss.

Estimated cost: $350-600 per side

Typical onset: 100,000-180,000 mi

Symptoms: Clutch pedal sinks to floor and stays there, Soft, spongy pedal feel, Difficulty shifting, especially into first or reverse, Fluid leak visible at firewall or bellhousing, Gradually increasing clutch engagement point

Fix: Both cylinders fail from age and corrosion. Replace both at once—if one fails, the other is close behind. Bleeding can be tricky. 2-3 hours total. If doing slave, inspect clutch fork and throwout bearing while accessible.

Estimated cost: $250-450
