2009 Land Rover Defender Problems: 4 Known Issues

On the 2007-2016 Land Rover Defender, the Ford-sourced MT82 6-speed (fitted to every Puma) has a notorious dry spline where the rear output shaft mates into the LT230 transfer box. Because that spline runs effectively unlubricated, it 'frets' and wears away exactly like the earlier LT77/R380 mainshaft splines, eventually rounding off and giving a complete loss of drive even though the engine and gearbox sound fine. It is widely believed a batch of Pumas also left the factory under-filled with gearbox oil, accelerating the wear. Restorers consider this, alongside the oil pump, the defining mechanical weak point of the era.

On the 2007-2016 Land Rover Defender, the Puma's MT82 uses a concentric slave cylinder (CSC) — the hydraulic release bearing lives inside the bellhousing around the gearbox input shaft. Its internal seal fails progressively, leaking clutch fluid internally with no external puddle, so the biting point drops toward the floor, the pedal goes spongy and eventually the clutch won't disengage and gears can't be selected with the engine running. Because the CSC is buried, replacing it means pulling the gearbox — exactly the job a restorer wants to do once, not twice.

On the 2007-2016 Land Rover Defender, the Puma kept a painted (not galvanised) steel ladder chassis, and the rear crossmember is the first thing to rot — it boxes water and mud around the towing/rear-body mounts and rusts from the inside out, often hidden under undseal. The chassis outriggers, rear inner wings and fuel-tank crossmember area go the same way on salted UK/EU trucks. Even relatively young Pumas need crossmember attention, and a previously-bodged crossmember repair is a common nasty surprise on a purchase inspection.

On the 2007-2016 Land Rover Defender, the belt-driven brake vacuum pump that supplies the brake servo has a front oil seal that hardens and leaks. Dirt ingress past the pump pulley seal damages the lip, and engine oil then weeps out — owners chase a mystery oil leak/oil consumption down the left side of the engine that isn't the sump or rocker cover. In the worst case air ingress reduces servo assistance, so it is a brake-relevant fault as well as an oil leak, and on a restoration it is an easy win to seal up while the engine is accessible.
