Chevrolet Suburban X (2007–2014) How to Remove the Bumpers

Production Years and Platform

The 2007–2014 Chevrolet Suburban belongs to the tenth generation of the model, which was based on the GMT900 platform (General Motors Truck 900). This was an updated architecture also used for the Tahoe, Yukon, and Silverado/Sierra pickups. The platform featured a reinforced frame, independent front suspension, and improved noise insulation.

Production of this generation began in 2006 (for the 2007 model year), and in 2013, the Suburban underwent a facelift with a revised grille, headlights, and interior. However, technically, it remained the same platform, and production continued until 2014, after which the model transitioned to the new GMT K2 platform.

Description and Model Code

The Suburban of this generation was offered in two wheelbase variants:

• Short wheelbase (Chevrolet Tahoe, model code GMT921);
• Long wheelbase (Suburban, model code GMT922).

The Suburban was traditionally positioned as a full-size SUV with seating for up to 9 passengers (depending on the interior configuration). The model's dimensions were:

• Length: 5.7 m;
• Wheelbase: 3.3 m;
• Ground clearance: approx. 25 cm.

Engines and Transmission

Throughout this generation, the Suburban was equipped with several powertrains:

• 5.3L V8 (LMF/LMG) – Base engine with Active Fuel Management (cylinder deactivation for fuel efficiency). Power: 320–326 hp, torque: 454–460 Nm.
• 6.0L V8 (LY6) – More powerful option (366 hp, 523 Nm), available in the 2500 version (with reinforced suspension and frame).
• 6.2L V8 (L92/L9H) – Top-tier engine (403 hp, 565 Nm), offered in limited trims.

All engines were paired with a 4- or 6-speed automatic transmission (4L60, 6L80). Drivetrain options included rear-wheel drive (RWD) or four-wheel drive (4WD) with the AutoTrac system.

How to Remove the Front Bumper

1. Lift the hood.
2. Under the hood, unscrew the six bolts securing the top side of the front bumper and the grille.
3. For convenience, turn the wheels to the side.
4. In the wheel arches, remove two clips each and unscrew two bolts on each side to free the fender liners.
5. Lie under the vehicle and unscrew two bolts (installed from the engine compartment side) securing the brackets to the metal reinforcement.
6. Release the clips in the fenders (grab the corner with your hands and pull sharply toward yourself).
7. With an assistant, remove the bumper forward (ensure electrical wires are not torn).
8. Disconnect the fog light connectors (if equipped) and other electronic components (if present).

How to Remove the Rear Bumper

1. Open the trunk lid.
2. In the trunk opening, unscrew six screws (of varying sizes) securing the top side of the rear bumper.
3. From the underside, unscrew four screws (installed from bottom to top).
4. In the wheel arches (on both sides), unscrew two screws and remove four clips.
5. Release the clips in the fenders (grab the corner with your hands and pull sharply toward yourself).

Interesting Facts

• The 2007–2014 Suburban was used by U.S. government agencies, including the FBI and Secret Service.
• In 2013, an LPG version with a 6.0L V8 engine was introduced.
• Despite its body-on-frame construction, the Suburban received 5 stars in NHTSA crash tests (2007).
• In 2009, the model was updated with Bluetooth and a USB port, which was rare for large SUVs at the time.

Advantages

• Spaciousness – One of the roomiest SUVs on the market, with a huge cargo area (up to 3420 liters with seats folded).
• Off-road capability – Thanks to all-wheel drive and high ground clearance, the Suburban handled light off-roading well.
• Reliability – GM’s V8 engines, especially the 5.3L and 6.0L, are known for their durability.
• Towing capacity – Up to 3900 kg (4500 kg for the 2500 version).

Disadvantages

• Fuel consumption – In city driving, the 5.3L V8 consumed 15–18 L/100 km, while the 6.2L could reach up to 22 L.
• Dimensions – Parking in the city could be challenging due to its nearly 6-meter length.
• Interior material quality – The plastic and trim were inferior to competitors (e.g., Ford Expedition).
• AFM issues – The cylinder deactivation system sometimes caused accelerated oil consumption.

Conclusion

The 2007–2014 Chevrolet Suburban is a classic example of an American full-size SUV: big, powerful, but not fuel-efficient. It’s an excellent choice for large families, outdoor trips, and towing, but it can be inconvenient in urban environments. Despite its age, many examples remain on the road thanks to their robust construction and straightforward maintenance.
