Door Alignment After Hinge Pillar Repair - Water Leak and Wind Noise
A vehicle had its right front door replaced and the hinge pillar pulled and repaired after a collision. The door now latches, but the customer reports wind noise at highway speed and water intrusion at the top rear corner of the door. Inspection shows the door is flush at the front edge but the rear edge sits about 4 mm inboard at the top, and the upper rear corner of the glass is about 3 mm low relative to the roof drip rail. The door hinges are bolted, not welded. Weatherstrip appears intact. The shop has a frame/body dimension printout showing the hinge pillar is within 2 mm of specification.
1. What is the most likely cause of the wind noise and leak, and how would you confirm it before adjusting?

The door is not seated correctly in its opening: the rear edge is inboard at the top and the glass corner is low, which reduces weatherstrip compression at the upper rear corner and opens a gap for wind and water. Since the hinge pillar is within 2 mm of spec, the issue is likely door-to-opening fit (hinge adjustment, striker adjustment, or a slightly twisted door shell) rather than structural misalignment. Confirm by checking gap and flush across all four edges, checking weatherstrip contact with a dollar-bill or chalk test around the full perimeter, and confirming the door is not twisted by measuring diagonal dimensions or checking with the latch and striker loosened. Only after confirming the shell is sound should you adjust hinges and striker.
2. Outline the adjustment sequence to correct the fit, and explain why order matters.

Loosen the striker first if it is preloading the door, then adjust the hinges: move the door rearward/outboard at the top by shimming or shifting the upper hinge, and set fore-aft position at the lower hinge. Recheck gaps and flush at all edges, then set the striker so the door latches without lifting or dropping and the weatherstrip is evenly compressed. Order matters because striker preload can mask or create hinge misalignment; adjusting the striker last ensures the door is positioned by the hinges and only held by the striker. After adjustment, recheck glass-to-drip-rail relationship and perform a water test at the upper rear corner. If the shell itself is twisted beyond hinge adjustment, the door must be replaced or repaired, not forced.
