Buy GMC Acadia Hood Hinges

Snapshot

GMC Acadia hood hinges - sometimes called hood brackets, bonnet hinges, or front-lid pivots - let the SUV's hood open and close smoothly while holding it steady against wind lift and vibration.

Part Role

The hinge mounts between the hood sheet-metal and the cowl, acting as a pivot so you can raise the hood for service or emergencies (GMC).
GM engineers tune the hinge to crush in a controlled way during a frontal impact and to deflect slightly in a pedestrian strike to soften head contact .

Fit Ranges

• First generation (2007-2016) - Larger Lambda-platform Acadia uses a heavier stamped-steel hinge set.
• Second generation (2017-2023) - Smaller, lighter body needed a revised hinge with different bolt spacing .
• Third generation (2024-present) - Redesigned and upsized again; the new body has even wider mounting ears, unique to 2024-25 builds .

Always match the hinge to the exact model year and side (left / right) to avoid alignment issues (Acadia Forum).

Failure Signs

• Hood sits high or low at rear corners
• Metallic pop or creak when opening (YouTube)
• Paint flaking off the hinge arm
• Visible bend, crack, or loosened spot-weld
• Hood shudder at highway speed

Diagnosis

Open the hood halfway and gently lift the sheet-metal up-and-down. Any extra play points to bushing or rivet wear. Compare the gap between hood and fender on both sides; if one gap closes, its hinge is likely tweaked (Acadia Forum).

Replacement Steps

1. Support hood with prop rod or helper.
2. Mark hinge outline on hood with masking tape for easy realignment.
3. Remove two cowl-side bolts, then two hood-side bolts.
4. Swap hinge, start bolts finger-tight.
5. Close hood slowly, nudge fore-aft to center gaps, then torque bolts per the service manual (usually 18-25 ft-lb; verify for your year) (Dealer eProcess).
6. Re-check gaps, road-test.

Materials & Design

Acadia hinges are high-strength stamped steel with a corrosion-resistant e-coat. The pivot pin uses a steel-on-steel sleeve so it can accept white-lithium grease or light engine oil .

Safety Notes

A seized hinge can stop the secondary safety catch from engaging, risking hood fly-up at speed. GM's performance testing calls for the primary latch plus hinge strength to withstand wind loads above 90 mph .

Care Tips

• Lube the pivot twice a year with spray lithium grease; wipe excess to prevent dust build-up .
• After any front-end hit, inspect hinge arms for subtle twist.
• Keep the drain trough below the hinge clear so water can't pool and rust it.

Related Parts

While servicing the hinge, also look at:

• Hood latch and secondary catch (same area, same lubrication needs) (GMC)
• Rubber bump stops that control closed height
• Gas struts (if equipped on AT4 or Denali trims)

Buying Tips

• Use VIN-matched part numbers-2007-2012 hinges differ from 2013-2016 even though both are first gen.
• Choose coated steel over bare steel if you live in a rust-belt climate.
• Some aftermarket versions add an extra gusset for off-road trims; check weight if every ounce matters.

Environmental Angle

Steel hinges are 100 % recyclable; most metal scrap yards accept them. Applying biodegradable grease cuts petroleum runoff during washes .

Frequently Asked Questions

Q: What does a hood hinge do?
A: It acts like a small door hinge, letting the GMC Acadia's hood (bonnet) swing open and shut while holding alignment with the fenders .

Q: How long should a hinge last?
A: Under normal use and yearly lubrication, 10-15 years is common before noticeable play develops .

Q: Can I adjust the hood height with the hinge?
A: Minor fore-aft and up-down tweaks are possible by loosening the bolts and shifting the hinge; height is mainly set by the rubber bump stops (YouTube).

Q: What noise points to a failing hinge?
A: A sharp creak or snap when you begin lifting-the sound of a dry or cracked pivot pin (YouTube).

Q: Is left the same as right?
A: No. The driver-side (LH) and passenger-side (RH) hinges mirror each other and are not interchangeable (Acadia Forum).

Q: Do later-model hinges fit early Acadias?
A: Second-generation (2017-23) and third-generation (2024-25) hinges use different bolt spacing, so they do not swap onto 2007-16 bodies .

Q: What lubricant is best?
A: GM recommends light engine oil; hobbyists often use spray white-lithium because it clings longer .

Q: Can I drive if one hinge is bent?
A: It's risky; the single good hinge now carries all wind load. Replace the damaged hinge before highway travel .

Q: Are hinges painted?
A: Yes. They come pre-primed black; you can top-coat to match the engine bay.

Q: Do hinges affect crash ratings?
A: Indirectly. Their controlled-crush design is part of GM's pedestrian-protection strategy .

Q: What tools do I need for DIY swap?
A: 10 mm or 13 mm socket (varies by year), torque wrench, masking tape, and grease gun for afterward.

Q: How can I recycle the old hinge?
A: Drop it at any metal-scrap center; most pay by weight and accept automotive steel .

Q: Will a new hinge fix a fluttering hood?
A: If flutter comes from worn hinge play, yes. If the latch or bump stops are loose, address those too (GMC).

Q: Do I need to remove the fender?
A: No. The hinge bolts are accessible with the hood up; only the under-hood sound pad may need moving.
