COMPATIBILITY

Land Rover Discovery 4 – L319

Verified Land Rover parts-catalogue fitment:

• Discovery 4 L319 – 2010-2016

• From VIN AA000001

• Split upper/lower tailgate models

• Right-hand lower tailgate position

• UK RHD and LHD vehicles – component position remains RH

for the Discovery 4 luggage-compartment door assembly.

Therefore, your 2010 Discovery 4 L319 is a directly supported application.

ADDITIONAL COMPATIBILITY

Land Rover Discovery 3 / LR3 – L319

BHF780040 is also fitted to later Discovery 3 vehicles.

Verified fitment includes:

• Discovery 3 / LR3

• From VIN 7A439052

• Right-hand lower tailgate

• Split-tailgate vehicles

Therefore, this part is not exclusive to the Discovery 4 and can also be useful to buyers searching for a late Discovery 3 replacement.

TAILGATE POSITION INFORMATION

This part fits the:

Rear

Lower Tailgate

Right-Hand Side

On a UK vehicle:

RH = Right Hand

O/S = Offside

Driver Side

The corresponding opposite-side component is:

BHF780050 – Left-Hand Lower Tailgate Stay

Therefore:

BHF780040 = RH / O/S

BHF780050 = LH / N/S

These should not be confused when ordering.

TECHNICAL INFORMATION

The Discovery 4 uses a distinctive split rear tailgate, consisting of an upper opening section and a lower fold-down tailgate.

The BHF780040 stay assembly forms part of the lower-tailgate support system.

Its functions include:

• Supporting the lower tailgate when open

• Controlling downward tailgate movement

• Limiting lower-tailgate travel

• Maintaining the correct opening position

• Supporting the weight/load acting through the lower tailgate

• Helping maintain correct tailgate alignment

• Reducing excessive load on associated hinges and mounting points

• Allowing controlled opening and closing of the lower section

The internal cable/reel arrangement allows the stay to operate compactly while providing the required support when the tailgate is lowered.

LOWER TAILGATE SYSTEM INFORMATION

The Discovery 4 lower tailgate system incorporates several separate components, including:

• RH Lower Tailgate Stay – BHF780040

• LH Lower Tailgate Stay – BHF780050

• Lower tailgate hinges

• Tailgate pivots

• Stay mounting plates

• Lower tailgate latch/locking system

• Release mechanism

• Wiring where applicable

• Lower tailgate structure

• Upper tailgate assembly

Land Rover’s parts catalogue lists BHF780040 and BHF780050 together within the Luggage Compartment Door / Door and Fixings assembly, confirming their respective RH and LH positions.

COMMON SYMPTOMS / REASONS FOR REPLACEMENT

Replacement may be required due to:

• Broken tailgate support cable

• Frayed cable

• Cable pulling out of the reel

• Damaged reel mechanism

• Lower tailgate dropping too far

• Tailgate not being supported correctly

• Uneven lower-tailgate support

• Excessive movement when opened

• Bent or damaged stay assembly

• Seized mechanism

• Corrosion

• Damaged mounting points

• Accident or impact damage

• Damage caused by excessive load on the open tailgate

If one side has failed, the opposite-side stay should also be inspected for wear.

IMPORTANT DIAGNOSTIC INFORMATION

Before replacing the stay assembly, inspect:

• RH BHF780040 stay/cable

• LH BHF780050 stay/cable

• Cable condition

• Reel operation

• Lower tailgate hinges

• Stay mounting points

• Tailgate alignment

• Tailgate latch operation

• Lower-tailgate structure

• Associated mounting hardware

If the lower tailgate sits unevenly when open, inspect both RH and LH stays rather than assuming only one component is responsible.

MODEL / ENGINE INFORMATION

This component is a body/tailgate part and is not engine-specific.

It can therefore be fitted to compatible Discovery 4 vehicles regardless of engine where the corresponding split-tailgate system is installed.

This includes selected:

• 2.7 TDV6

• 3.0 TDV6

• 3.0 SDV6

• Petrol applications depending on market

INSTALLATION

Installation should be carried out according to the appropriate Land Rover workshop procedure.

During replacement:

• Support the lower tailgate securely before removing the stay

• Do not rely on the remaining cable to support the tailgate

• Compare the replacement with the original

• Confirm RH orientation

• Inspect mounting points

• Inspect the opposite LH stay

• Check the lower-tailgate hinges

• Install the stay securely

• Use the correct mounting hardware

• Tighten fasteners to Land Rover specifications

• Carefully test the opening movement

• Confirm the tailgate stops at the correct position

• Check that both sides support the tailgate evenly

The lower tailgate should be physically supported during removal and installation because removing a stay changes how the tailgate’s weight is supported.
