Brake judder from wheel nuts over-tightened or tightened unevenly (Toyota tech tip)Brakes
- Engine / equipment
- Any Toyota: it depends on how the wheels are tightened
- Period mentioned
- 2016 tech tip for all its models
- Symptoms
- Vibration in the steering wheel and the pedal when braking, even gently and at any speed, often shortly after wheels, pads or discs were changed.
- Possible cause described
- Toyota points out in a tech tip that if the wheel nuts are over-tightened or tightened unevenly (a single one is enough), the brake disc is left with runout and brake judder appears. It happens above all when they are run fully home with an impact gun instead of a torque wrench in a star pattern.
- Check for the garage
- Ask the garage to loosen and re-tighten the nuts with a torque wrench, to the manual's torque and in a star pattern, and to measure whether the discs have been left warped; if so, they will need skimming or replacing.

Crankshaft sensor, EGR, wiring and front suspension on the Ducato (from 2006)Known weak points
- Engine / equipment
- Fiat Ducato 2.2 and 2.3 Multijet (also Peugeot Boxer and Citroën Relay/Jumper)
- Period mentioned
- 2006 onwards
- Symptoms
- The engine cuts out when warm and will not restart until it cools (P0335); hesitation and rough idle from the EGR; code P0482 from corroded wiring; increasingly heavy steering, squeaking strut mounts; brake or reversing lights that fail; a new clutch that slips.
- Possible cause described
- According to the UK trade magazine CAT: the crankshaft sensor fails at around 80,000 km; the EGR is better replaced than cleaned; the wiring loom corrodes (2.3); windscreen water gets into the gearbox through a badly routed drain pipe; gearbox oil leaks make the clutch slip; the top strut mounts and steering rack suffer from heavy use.
- Check for the garage
- Read codes (P0335, P0482); check the windscreen drains and gearbox oil; fix leaks before replacing the clutch; check strut mounts and light wiring.
