Replace or repair the door check/stop mechanism that controls door opening resistance and holds the door in open positions on a 2008 Dodge Viper.

Warnings

Tools required

Parts

• Door check/stop assembly × 1 — Mopar 55077372AA or equivalent

Preparation

1. Open the driver or passenger door fully and position a padded jack stand or assistant to support the door weight
2. Inspect the hinge area between the door and B-pillar to identify the check/stop mechanism location

Procedure

1. 1

   Access the door check/stop mounting area
   Open the door to approximately 45 degrees. The door check/stop is visible at the forward lower hinge area where the door meets the body. On the Viper, verify the door check location and whether interior door trim panel removal is required to access the door-side fastener before proceeding.
2. 2

   Remove door check/stop fasteners
   Using the correct Torx or hex bit (size unverified for this vehicle - confirm before starting), remove the fasteners securing the check/stop arm to the door or body side of the hinge (fastener count unverified - inspect to confirm). The exact mounting configuration may be to the door inner structure or the B-pillar reinforcement.
   ⚠As you remove the final fastener, be prepared for the door to swing more freely - ensure your support is secure
3. 3

   Extract the check/stop assembly
   Withdraw the check/stop arm from its mounting position. Note the orientation of any washers, bushings, or spacers for reinstallation. The roller or detent mechanism should come away with the arm.
4. 4

   Inspect mounting points and hinge
   Examine the mounting holes in both the door and body for elongation, cracks, or thread damage. Check the hinge pin area for wear or looseness. If replacement is due to door sagging, inspect the entire hinge assembly for play or damage.
5. 5

   Prepare new or serviced check/stop
   If installing a new check/stop, compare it to the removed unit to confirm correct application. Apply a small amount of lithium grease to the roller or detent contact points. Ensure any bushings or washers are properly positioned on the new assembly.
6. 6

   Install check/stop assembly
   Position the check/stop arm into its mounting location, aligning the fastener holes with the door or body structure. Insert all fasteners finger-tight to ensure proper alignment before final tightening.
7. 7

   Torque fasteners
   Tighten the check/stop mounting fasteners in a cross pattern if multiple fasteners are used. Without manufacturer torque specifications available, tighten securely without overtightening; consult the factory service manual for the correct torque spec (small M6-M8 fasteners of this type are commonly in the 7-17 ft-lbs range) and use judgment based on thread engagement and component construction.

Reassembly

1. No additional reassembly required - the door check/stop is the only component removed

Verification

• Slowly open the door through its full range of motion - you should feel distinct detent positions where the door holds itself open
• Verify the door stops at the same positions as the opposite door (if applicable)
• Check that the door does not swing freely or require excessive force to open
• Confirm no rattling or clicking noises from the hinge area during opening and closing
• Inspect for proper door alignment - if the check/stop was replaced due to sagging, the door should now align correctly with the body
