Below is a focused, step‑by‑step turbocharger repair procedure for Ford Trader T3000/T3500/T4000 trucks (diesel). Follow the factory service manual for exact torque values, bolt patterns, and turbo model numbers. Observe all safety precautions.

Tools & equipment
- PPE: gloves, safety glasses, hearing protection, respirator when cleaning carbon.
- Hand tools: metric socket set (deep + shallow), ratchet, breaker bar, combination wrenches, Allen keys, screwdriver set, pliers.
- Torque wrench (0–200 Nm range).
- Penetrating oil (e.g., PB Blaster), anti‑seize (use only where specified).
- Snap‑ring pliers, pick set, gasket scraper.
- Bench vise with soft jaws or dedicated turbo workbench fixture.
- Dial indicator (0.01 mm resolution) and magnetic base for axial/radial play checks.
- Micrometer or calipers for measuring wheel damage.
- Compressed air, lint‑free rags, solvent (decarboniser).
- Clean oil supply (fresh engine oil), oil priming syringe or small pump.
- Vacuum/boost pump to test turbo actuator.
- Replacement parts: turbo gasket set, new oil feed and return lines (and crush washers), new CHRA (recommended) or full turbo assembly, V‑band clamps or studs/nuts if corroded, actuator or linkage if faulty.
- Optional/specialty: turbo balancing machine (shop service), dedicated compressor/turbine wheel puller, stud extractor.

Safety & prep
- Work on a cool engine. Hot exhaust/turbo can cause severe burns.
- Disconnect battery negative terminal.
- Drain oil if required and contain/collect used oil and coolant properly.
- Support truck safely: park on level, chock wheels, use jack stands if lifting.
- Keep open flames and sparks away (oil/fuel vapors).
- Label hoses, lines, vacuum pipes, and electrical connectors for reassembly.

Step‑by‑step repair

1) Diagnose and confirm turbo fault
- Symptoms: heavy smoke, loss of boost, loud shaft noise, oil consumption, turbo whistle/scrape.
- Quick checks: inspect compressor intake for shaft play (axial >0.2–0.5 mm or radial >0.1–0.2 mm is bad), oil in intercooler/pipes, exhaust leaks at manifold/turbo flange, actuator operation with vacuum pump.
- If compressor/turbine blades are chipped, missing, or shaft contact evident → rebuild/replace.

2) Remove intake and exhaust connections
- Remove air intake hose, inlet pipe, and intercooler connections. Use screwdrivers/ratchet.
- Remove downpipe/exhaust connection at turbo (V‑band or flange). Apply penetrating oil; use breaker bar for seized nuts.
- Label and remove any EGT or temp sensors carefully.

3) Remove oil and coolant lines
- Cap or plug oil feed and return ports immediately to prevent contamination.
- Remove feed and return lines. Use a line wrench to avoid rounding banjo bolts. Expect carbon/oil sludge in return line—inspect/replace.
- Replace crush washers/banjo gaskets as required.

4) Remove turbo from manifold
- Remove actuator linkage or vacuum hose (note orientation).
- Unbolt turbo mounting nuts/studs and remove turbo assembly. Use penetrating oil and heat (if allowed) for seized studs. If studs break, extract or replace stud—do NOT reuse broken hardware.
- Keep bolts/nuts organized.

5) Disassemble turbo (if rebuilding)
- Mount turbo center housing (CHRA) in soft‑jaw bench vise.
- Remove compressor housing bolts or V‑band clamp.
- Remove compressor wheel retaining nut (note direction). Use a compressor wheel holder or strap wrench; keep wheel nut orientation/threads in mind.
- Remove snap ring(s) and slide off compressor wheel, bearing housing, and turbine wheel.
- Use proper pullers if tight.

Tool usage notes:
- Snap‑ring pliers remove circlip retaining bearing assembly.
- Compressor wheel holder prevents wheel rotation while undoing nut.
- Bench vise with soft jaws holds housing without damaging.

6) Inspect components
- Check shaft for straightness and scoring.
- Measure radial and axial play with dial indicator. Compare to spec; excessive play indicates worn bearings/seals → replace CHRA.
- Inspect compressor and turbine wheels for nicks, cracks, erosion. Small nicks may be unacceptable—balance will be compromised.
- Inspect housings for cracks (esp. turbine housing) and warping.
- Inspect actuator diaphragm and linkage; test opening/closing with vacuum pump.

7) Repair or replace parts
- Recommendation: replace CHRA or install a complete replacement turbo assembly unless you have access to professional balancing equipment and replacement wheels. Replacing bearings/seals in the field without balancing risks premature failure.
- Replace: gaskets, seals, oil feed/return lines, crush washers, V‑band clamps, studs/nuts if corroded, actuator if faulty.
- If compressor or turbine wheels are replaced individually, send to a turbo shop for dynamic balancing.

8) Clean and prepare mating surfaces
- Clean carbon from exhaust manifold mating surface and turbo flanges. Use scraper and solvent; avoid debris entering oil passages.
- Blow out oil feed/return ports with compressed air until clean. Ensure no debris left in lines.

9) Reassemble turbo (or fit new unit)
- If fitting rebuilt CHRA/full turbo: install new gaskets and use new crush washers on oil feed/banjo bolts.
- Torque all bolts to factory specs. Use torque wrench; do not overtighten studs/nuts.
- If reassembling internals yourself: install new bearings/seals, replace snap rings, reinstall compressor wheel and torque retaining nut to spec; check axial/radial play, then balance (shop).

Tool usage notes:
- Torque wrench: apply correct torque in sequence; torque to spec—refer to manual.
- Anti‑seize: only where specified (some studs require dry threads).
- Vacuum pump: test actuator response and measure opening point.

10) Reinstall turbo on engine
- Fit turbo to manifold, tighten nuts/studs to spec.
- Reconnect oil feed line (ensure clean oil feed); reinstall return line (gravity/drain route intact).
- Reconnect coolant lines if applicable; bleed cooling system per procedure.
- Reattach intake/intercooler pipes and exhaust downpipe; replace exhaust gaskets.
- Reconnect sensors and vacuum hoses.

11) Prime turbo oil supply
- Fill engine to correct oil level.
- Prime turbo by cranking engine without starting to build oil pressure (disable fuel supply or ignition by removing fuel pump relay/fuse or disconnecting injector pump wiring—follow safe shop procedure). Crank for ~10–15 s, then wait 30 s, repeat 2–3 times. This allows oil to reach bearings before first start.
- Alternatively, use an oil priming syringe/pump into the oil feed port to force oil into CHRA.

Safety note: follow workshop procedure for disabling engine start; ensure neutral gear and parking brake, wheels chocked.

12) Start‑up and checks
- Start engine and idle. Observe oil pressure, listen for abnormal noises (rattles/scrapes). Check for oil leaks at feed/return and seals, exhaust leaks, boost leaks, and coolant leaks.
- Allow warm up and rev gently; do not full‑throttle for first 10–20 minutes.
- Recheck torque on accessible turbo studs after initial heat cycle (if manual recommends).
- Road test, monitor boost and engine performance. Check for excessive smoke or oil consumption.

Common pitfalls & how to avoid them
- Not replacing oil feed/return lines and crush washers: causes leaks and starvation—replace both.
- Not cleaning oil passages: sludge will clog feed and ruin new turbo—flush and blow out.
- Reusing damaged studs, gaskets, clamps: leads to leaks and failures—always replace corroded hardware.
- Reusing a worn CHRA or unbalanced wheels: causes immediate vibration and failure—use new CHRA or have parts balanced professionally.
- Improper torque or anti‑seize misuse: can cause studs to stretch or seize. Always use torque wrench and follow spec for anti‑seize.
- Not priming oil: dry start kills bearings. Always prime before first run.
- Ignoring actuator calibration: incorrect wastegate/actuator setup causes over/under boost—test and set per spec.
- Contamination during rebuild: keep work area clean; cap open ports immediately.

When to replace vs rebuild
- Replace entire turbo or swap in a reman turbo/CHRA if shaft play present, major blade damage, cracked housings, or no in‑shop balancing capability.
- Rebuild only if you have clean parts, new seals/bearings, and access to professional balancing.

Time estimate
- Remove/replace a turbo: 2–6 hours depending on seized fasteners and access.
- Full teardown, rebuild and balancing: send to turbo shop — allow 1–3 days.

Final notes
- Always use OEM or reputable aftermarket replacement parts sized to the turbo model stamped on the unit.
- Keep the service manual for torque specs and sequence.
- If you lack a turbo balancing machine or advanced press/puller tools, use a complete reman turbo or professional rebuilder.

End.
