The fault
How you spot it
In the smaller models, the Fiesta, the Fusion and the B-Max, the IB5 holds up well, but in the larger Focus and especially the Mondeo it does less well: there the engine torque and the weight of the car put a heavier load on the same gearbox.
The synchros and the gears can wear before 100,000 km, and around 150,000 km the differential bearings need replacing. On cars with the 1.8-litre engine the differential pinion pin often breaks when the wheels spin.

How we know
Information, not an expert opinion
We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.
- A fault on the list does not mean the car you are looking at has it.
- A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
- You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
