How to remove old Defender door hinges

Key Takeaways

• Remove check straps before attempting to detach doors to prevent unnecessary strain

• Using a grinder near bolt heads creates better access for stubborn fasteners

• Working systematically through each door helps maintain control during the removal process

Overview of Hinge Removal Process

When removing door hinges from an older vehicle, you may encounter seized or spinning bolts that resist traditional removal methods. Focus your efforts on removing the hinges from the A and B pillars rather than the doors themselves.

Start by attempting to remove any accessible bolts with standard tools. If you encounter worn bolt heads that spin freely, a grinder becomes necessary.

Important Safety Tip: Before grinding, ensure the doors remain engaged to prevent unexpected movement during the removal process.

For stubborn bolts:

• Cut as close to the bolt head as possible with the grinder

• Keep the door supported whilst working

• Remove the check strap before final door removal

• Watch for captive plates behind the hinges

Time-Saving Technique: Remove the check strap first to prevent damaging components when lifting the door away from the body. This step proves particularly valuable with worn or seized bolts.

The removal sequence:

1. Remove accessible bolts with standard tools

2. Grind stubborn bolt heads

3. Detach check strap

4. Lift door clear of hinge points

Preparation for Hinge Removal

Identifying Removal Points on A and B Pillars

The hinge bolts connecting to the A and B pillars require careful assessment before removal. You'll need to locate the mounting points where the hinges attach to both pillars. Some bolts might turn but spin in place, making traditional removal methods ineffective.

A grinder offers the best solution for severely worn bolt heads. Position the grinder as close to the bolt head as possible for precise cutting. The doors' weight will keep them stable during this process, preventing unexpected movement.

Decision to Keep Hinges on Doors

The hinges remain attached to the doors to maintain their complete assembly state. This choice eliminates the need to remove door cards and interior components.

Before lifting the doors away, you must:

• Remove any accessible bolts with standard tools

• Detach the check straps

• Cut remaining seized bolts if necessary

• Ensure proper support when lifting doors clear

Important Safety Note: Always remove the check strap before attempting final door removal to prevent damage to both the strap and door components.

Dealing with Worn Bolt Heads

Assessment of Bolt Conditions

Worn bolt heads on door hinges present a unique challenge during removal. When standard tools fail to grip the bolt heads properly, you'll notice them spinning without loosening. This often occurs with older vehicles where corrosion and wear have damaged the bolt heads beyond normal use.

Using the Grinder for Bolt Removal

A grinder serves as an effective solution when traditional tools prove ineffective. Position the grinder as close to the bolt head as possible for precise cutting. The doors' weight and positioning help maintain stability during the grinding process.

Important Safety Points:

• Ensure doors are properly supported

• Wear appropriate protective equipment

• Maintain steady control of the grinder

Practical Tips for Grinding Near Bolt Heads

Remove the check straps before attempting bolt removal. This prevents unnecessary strain on the components during the process. Keep your cuts close to the bolt heads to maintain enough material for gripping if needed.

Best Practices:

• Remove accessible bolts with standard tools first

• Work systematically from top to bottom

• Watch for captive plates behind the hinges

• Cut gradually to maintain control

Removing the Doors

Procedure for Detaching the First Door

You'll need to remove the hinges from the A-pillar whilst leaving them attached to the door itself. This preserves the door's completeness for resale without requiring removal of door cards.

The worn bolt heads may resist traditional tools. In such cases, utilise an angle grinder to cut as close to the bolt heads as possible. The doors should remain stable during this process due to their engaged position.

Important Tips:

• Remove accessible bolts first with standard tools

• Watch for spinning bolts that refuse to extract

• Locate and remove captive plates

Sequential Removal of Remaining Doors

Remove the check straps before lifting each subsequent door. This prevents any unnecessary yanking or damage during removal.

Door Removal Steps:

1. Detach check strap

2. Support door weight

3. Lift door clear of hinges

If stubborn bolts persist, cut them closer to access the rear sections. Each door should lift away cleanly once all fixing points are freed.

Special Considerations

Handling Captive Plates and Spinning Bolts

When removing door hinges, you'll encounter captive plates behind the bolts. These plates shouldn't fall away whilst the door remains engaged. If you find the bolt heads are too worn to remove with standard tools, use a grinder to cut as close to the head as possible. This technique proves invaluable for older vehicles where bolt removal becomes challenging.

Some bolts might turn without loosening - a situation where they simply spin in place. When this occurs, careful grinding becomes your most effective solution. After creating the initial cut, you can often access the remaining bolt portion from behind.

Importance of Check Strap Removal

Always remove the check strap before attempting to lift off the door. Failing to do so risks damage to both the door and the vehicle frame. The check strap serves as a crucial safety mechanism, and yanking the door off whilst it remains attached can cause unnecessary strain.

The removal process becomes significantly smoother when you:

• Locate the check strap connection points

• Remove all securing bolts

• Detach the strap completely before door removal

• Lift the door clear of its mounting points

Finalising the Removal

Ensuring Complete Detachment

Remove the hinges from the A-pillar and B-pillar whilst leaving them attached to the doors. The doors will be sold as complete units, which eliminates the need to remove door cards. When faced with worn bolt heads, standard tools might not suffice. A grinder becomes essential for tackling these stubborn fixings.

Cut as close to the bolt heads as possible whilst the doors remain engaged. This technique prevents the doors from falling unexpectedly. Some bolts may spin without loosening—a rare but challenging situation.

Achieving Clearance for Hard-to-Access Areas

The check straps must be disconnected before lifting each door away. Remove accessible bolts first, then progress to those requiring the grinder. For bolts with captive plates, ensure proper support during removal.

Key steps for door removal:

• Remove check straps before final door separation

• Support the door weight during bolt removal

• Cut close to bolt heads when using the grinder

• Clear access to rear bolt areas for better grip

Pro tip: Always remove the check strap first to prevent door damage during the final stages of removal.
