SAFETY RECALL / HISTORICAL RECORD
Land Rover rear driveshaft coupling recall: replacement parts in older vehicles
The affected item was a service replacement part, so the campaign had to trace sales and repairs rather than rely solely on original vehicle production.
P024 / 12E010
A Land Rover US service bulletin dated 19 March 2012 announced P024, also recorded as NHTSA equipment campaign 12E010. The subject was a genuine replacement rear driveshaft coupling, part number TVF100010, manufactured from April through November 2011 outside the required engineering specification.
The bulletin identified 180 service parts shipped to the United States and federalised territories. It listed applications in 1995–1999 Discovery, 1999–2004 Discovery II and 1995 Range Rover vehicles. These were older cars that could receive the replacement component, not newly manufactured 2012 vehicles.
At a glance
- Manufacturer campaign P024; NHTSA equipment campaign 12E010.
- US notification bulletin: 19 March 2012.
- Part number TVF100010.
- Defined component production: April–November 2011.
- 180 service parts in the stated US population.
- Remedy: replacement with a coupling meeting the design specification.
How the coupling could deteriorate
The bulletin linked the concern to torque reversals occurring during ordinary driving. A non-conforming coupling could begin separating early in its service life, creating increased driveline vibration. Continued operation after that warning could result in catastrophic failure.
The stated consequences included detachment of the driveshaft while the vehicle was moving, loss of drive and loss of transmission Park functionality. This was a mechanical driveline defect; the reference to Park did not mean that a rotary selector or transmission-control software was the campaign’s root cause.
Finding a replacement part after it had been sold
A factory production list cannot fully identify the later recipients of a service component. Some couplings could be installed through workshop repair orders, while others could be sold over the counter or through wholesale channels.
A follow-up parts bulletin dated 15 May 2012 requested retailer sales records for the relevant period. It distinguished repair orders, identifiable counter or wholesale purchasers, and quantities sold where purchaser details were unavailable. The records request demonstrates the difference between a vehicle recall population and an equipment batch that may have moved through several sales paths.
Stock identification and the official remedy
The March instructions required inspection and quarantine of relevant stock, including the supplier-code check FA8FB and the component identification illustrated in the bulletin. The official comparison showed moulded markings on a conforming component and no markings on the illustrated non-conforming example.
Those were campaign-specific identification instructions, not a universal way to approve any coupling in the present aftermarket. The required vehicle correction was replacement with a component manufactured to the proper design specification, without charge to the purchasers under that campaign.
Reading the application list carefully
The March US bulletin and the May Canada/US records request did not use exactly the same Discovery model-year wording: the later request included 1994–1999 Discovery. The documents also had different market scopes. They should be retained as separate records rather than flattened into a new worldwide population.
For an individual older vehicle, replacement-part history is therefore important alongside its VIN and original specification. A matching model name does not prove that the affected batch was installed, and an apparently original build date cannot exclude a later service-part campaign.
Historical campaign information. Applicability and completion must be checked against the individual vehicle’s VIN and market records.
