  Q: How Should Door Hinges Be Serviced and Installed to Minimize Realignment on Buick Terraza?

  A:

  Door realignment stays minimal when servicing door hinges as single units because body and door sides operate as a pair and repair each hinge individually before changing any malfunctions. The body-side door hinge contains three bolts where two measure 13 mm while the remaining one measures 10 mm. Never detach these bolts since the cone accessory attached to the hinge's back will drop to the A-Pillar base unless needed for construction. It starts by placing masking tape across three areas specifically between door and rear door and door and rocker panel. Cut the tape at the hole section with a utility knife or alternative tool after which the hinge attachment regions should get cleaned fully using a rag while marking the corresponding body attachment areas using a grease pencil or suitable marker for reference. The door support process requires you to start by taking off the body side hinge bolts from the hinge before moving to door side hinge bolts from the door and finally removing the entire assembly alongside the cone adjuster bolt installed on the hinge. The first step for installation requires attachment of the cone adjuster bolt to the hinge before tightening it to 10 Nm (89 lb in). Place the new hinge into the markings before securing the specified door side hinge bolts to the door through points 1 to 2 or points 3 to 4 and tightening them to 33 Nm (24 lb ft) according to installation procedure. Fasten the upper/lower body side hinge bolts onto the hinge before tightening them to 33 Nm (24 lb ft). The worker needs to remove both the door supports along with reference tape from the door and the rocker and quarter panel area. The front door needs a final inspection regarding its up and down movement and in and out movement as well as its fore and aft position with corrective actions if needed.

  Q: How to replace the front side door hinge on Buick Terraza?

  A:

  Replacing the front side door hinge requires attention to repaired hinges as assemblies and pairs and prohibites the simultaneous removal of both door hinges because it causes door alignment issues. This procedure needs to repair one hinge at a time and replace any damaged hinges before proceeding. The 10mm and two 13mm attaching bolts on the body side door hinge need to stay in place because removing them allows the cone on the back hinge to enter the A-Pillar areas. Masking tape should be applied to door gap areas with utility knife cut lines that overlap between each door and the rocker panel and the rear door or quarter panel. Use a rag to clean all hinge mounting surfaces on the door and body and use a grease pencil to indicate the hinge positions on body surfaces. First secure the door before taking out the upper or lower body side hinge bolts and door side hinge bolts as well as the entire hinge assembly. Install the cone adjuster bolt to the hinge after which tighten it to 10 N.m (89 lb in). Insert the new hinge in the marked body locations and bolt each door side hinge to its respective slot before tightening them to 33 N.m (24 lb ft) according to the lettered sequence. Secure the upper or lower body side hinge bolts to the hinge after tightening them to 33 N.m (24 lb ft). Remove the door supports together with the reference tape from the door and both the rocker and quarter panel. The final inspection checks the front door for movements along all directions before any required adjustments are done.
