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.

Common Symptoms

  • Sudden total loss of drive with engine still running
  • Graunching/grating felt through the floor under load
  • Metallic debris on transfer box drain magnet
  • Clutch fine but no power to wheels
  • Noise that varies with road speed not engine speed

How to Fix

Proven bulletproofing: (1) Pull the transfer box and inspect/measure the output-shaft spline as a matter of course during a build — re-spline or replace the output shaft before it strips rather than after. (2) On reassembly, smear the spline with a high-quality moly/anti-fret grease (the 'dry spline' fix) so it is never run dry again. (3) Verify and correct the MT82 oil level/fill (MTF94 or GL-4 75W-90) — under-fill is a known contributor — and adopt a ~80k service interval. (4) Fit the LTB00585 selector-bush update and an uprated selector detent kit while the box is out to cure the related clunky/notchy change.

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.

Common Symptoms

  • Clutch biting point dropping toward the floor
  • Spongy/inconsistent clutch pedal
  • Clutch fluid reservoir dropping with no visible leak
  • Crunching into gear / can't select gears with engine running
  • Clutch fails to fully disengage

How to Fix

Bulletproofing: (1) Never replace a CSC on its own — when the box is out for any reason, fit a full clutch kit AND an uprated CSC together so the whole clutch system is fresh for the rebuild. (2) Use a quality/OE-spec or heavy-duty CSC rather than the cheapest pattern part, which is the part most likely to fail again early. (3) Bleed the system properly (the CSC is awkward to bleed) and replace the clutch hydraulic line/master if tired. (4) Combine the job with the MT82 spline/selector and gearbox-oil work above so one gearbox-out covers every known transmission weak point.

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.

Common Symptoms

  • Flaking/scaling rust on rear crossmember
  • Crunchy or holed metal around tow hitch and rear body mounts
  • Previous welded patch repairs found on inspection
  • Rotten outriggers / fuel-tank crossmember
  • MOT advisory or fail for chassis corrosion

How to Fix

The restoration-grade fix: (1) Fit a hot-dip galvanised replacement rear crossmember (Heritage HA0103G / DDS LR613-type), galvanised inside and out, rather than a painted mild-steel patch — then it never comes back. (2) On heavily-rotted trucks the bulletproof answer restorers choose is a full galvanised replacement chassis (Richards/Shielder/TerrainTech), which resets the whole vehicle. (3) After welding any crossmember, flood the internal cavity with Waxoyl/Dinitrol and re-treat the outriggers and tank crossmember. (4) Keep the chassis breathing/draining and re-wax the underside every couple of winters.

On the 2007-2016 Land Rover Defender, the camshaft-driven tandem vacuum/fuel 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.

Common Symptoms

  • Oil staining/weep down the left side of the engine bay
  • Gradual oil consumption with no sump or rocker leak
  • Reduced brake servo assistance / harder pedal
  • Oil around the vacuum pump / pulley area

How to Fix

Bulletproofing: (1) Replace the vacuum-pump front oil seal with the correct seal kit rather than ignoring the weep — and keep the pulley/seal area clean so grit doesn't re-chew the new lip. (2) If the pump body or internal vanes are worn, fit a complete uprated pump assembly rather than reseal a tired unit. (3) Confirm full servo vacuum after the repair (and check the non-return valve and servo hose) so braking assistance is restored. (4) Degrease and inspect afterwards so any future leak is obvious against clean metal.
