Hey guys! So, you're looking to remove the front bumper from your Infiniti IG37 sedan, huh? Maybe you're planning a cool upgrade, fixing some damage, or just curious about what's involved. Whatever the reason, you've come to the right place. This guide will walk you through the process, making it as straightforward as possible. We'll cover everything from the tools you'll need to the specific steps for a successful removal. Let's get started!

Tools and Materials You'll Need

Before we dive into the nitty-gritty, let's gather your arsenal. Having the right tools on hand will make this job a whole lot easier and prevent unnecessary headaches. Here's a list of essentials:

• Socket Set: A comprehensive set is ideal, but make sure you have the common sizes like 10mm, 12mm, and 14mm. You'll need both standard and deep sockets. These sizes are typical for automotive fasteners. Having a variety ensures you're prepared for whatever you encounter.
• Ratchet and Extensions: A good quality ratchet with a few extension bars will be your best friend. Extensions are crucial for reaching those bolts tucked away in hard-to-access spots. Different lengths give you flexibility.
• Screwdrivers: Both Phillips head and flathead screwdrivers are essential. You'll likely encounter various clips and fasteners that require these. Make sure you have a few different sizes for versatility.
• Trim Removal Tools: These plastic pry tools are a must-have. They're designed to safely remove plastic trim pieces and clips without damaging them. Using screwdrivers can scratch your paint, so invest in a set of these. They're inexpensive and will save you a lot of trouble.
• Jack and Jack Stands: Safety first! You'll need to lift the front of the car to access some of the undercarriage bolts. Never work under a car supported only by a jack; always use jack stands.
• Wheel Chocks: Place these behind the rear wheels for added safety, especially if you're working on an incline.
• Gloves: Protect your hands from dirt, grime, and sharp edges. Nitrile gloves work great.
• Work Light: A good work light will illuminate those hard-to-see areas, making the job much easier.
• WD-40 or Penetrating Oil: Sometimes bolts can be stubborn. Applying some penetrating oil a few minutes before you try to remove them can make a huge difference.
• Painter's Tape: Use painter's tape to protect painted surfaces from scratches while you're working around the bumper. It’s also helpful for marking the position of parts before you remove them.
• Optional: Impact Wrench: An impact wrench can speed up the process, but it's not essential. If you have one, make sure to use it with care to avoid stripping bolts.
• A friend: It's always helpful to have an extra pair of hands, especially when it comes to maneuvering the bumper.

Before you start, make sure your car is parked on a level surface, the engine is turned off, and the parking brake is engaged. Also, disconnect the negative terminal of your car battery for added safety. Safety is very important!

Step-by-Step Removal Guide

Alright, now that you've got your tools ready, let's get down to business. Here's a detailed, step-by-step guide to removing your IG37 sedan's front bumper. We'll break it down into manageable chunks to make the process as clear as possible.

Step 1: Prepare the Vehicle

• Safety First: As mentioned before, park your car on a level surface, engage the parking brake, and disconnect the negative terminal of the car battery. This prevents any electrical mishaps while you're working. Make sure the wheels are chocked.
• Loosen Wheel Bolts: Before jacking up the car, loosen the lug nuts on both front wheels. Don't remove them completely; just break them loose. This will make it easier to remove them once the car is in the air.

Step 2: Jack Up the Car and Secure with Jack Stands

• Find the Jacking Point: Locate the designated jacking point on the front frame of your IG37. Consult your owner's manual if you're unsure. Place your jack securely under this point.
• Lift the Car: Slowly raise the front of the car until you have enough room to work underneath. Be sure to lift the car high enough so you can easily access the bolts under the bumper.
• Position Jack Stands: Place the jack stands under the appropriate jack stand points on the frame. These are typically reinforced areas designed to support the car's weight. Lower the car onto the jack stands, ensuring they are stable and secure. Double-check that the car is firmly supported before proceeding.

Step 3: Remove the Fasteners Under the Bumper

• Locate the Bolts: Crawl under the front of your car and locate the bolts that secure the bumper to the undercarriage. These are usually along the bottom edge of the bumper. There are typically multiple bolts, and they may be covered by a plastic splash shield.
• Remove the Splash Shield: If there is a splash shield, remove it. This usually involves removing several screws or plastic clips. Use your screwdriver or trim removal tools for this. Once the fasteners are removed, the shield should come off easily.
• Remove the Bolts: Using your socket wrench, remove the bolts that secure the bumper to the frame. WD-40 or penetrating oil can be helpful here if the bolts are corroded. Take your time and be careful not to strip the bolt heads. Place the bolts in a safe place so you don’t lose them.

Step 4: Remove the Fasteners Inside the Wheel Wells

• Locate the Fasteners: Inside each wheel well, you'll find fasteners that connect the bumper to the fender. These are often plastic clips or screws.
• Remove the Fasteners: Use your trim removal tools or screwdriver to carefully remove these fasteners. Be gentle to avoid breaking the clips. If they are screws, unscrew them carefully. If you encounter any stubborn clips, don't force them. Work them loose gradually.

Step 5: Remove the Fasteners on Top of the Bumper (Grille Area)

• Open the Hood: Pop the hood of your IG37 sedan and prop it open securely.
• Locate the Fasteners: You'll find fasteners along the top edge of the bumper, where it meets the hood latch area and the grille. These are usually bolts or clips.
• Remove the Fasteners: Using your socket wrench or screwdriver, carefully remove these fasteners. You might need to remove the grille first to access some of them. If the grille needs to be removed, there may be screws, clips, or a combination of both. Be careful not to damage the grille.

Step 6: Disconnect Any Wiring

• Identify Wiring: As you start to loosen the bumper, you'll likely encounter wiring for fog lights, parking sensors, or other accessories. Carefully identify all the wires connected to the bumper.
• Disconnect the Wiring: Detach these wires. Usually, they have connectors that you can simply unplug. Be gentle and take your time to avoid breaking any clips or connectors. If you're unsure about the wiring, it's a good idea to take pictures before disconnecting anything so you can refer to them during reassembly.

Step 7: Detach the Bumper

• Grab a Friend (Recommended): This step is much easier with a friend. One person can support the bumper while the other disconnects any remaining fasteners.
• Gently Pull Away: Once all fasteners and wiring are disconnected, gently pull the bumper away from the car. Start from the sides and work your way towards the center. The bumper should come off easily if all fasteners are removed. Don't force it; if it seems stuck, double-check for any missed fasteners.
• Maneuver the Bumper: Carefully maneuver the bumper away from the car. You might need to wiggle it a bit to clear any remaining clips or attachments.
• Set the Bumper Aside: Place the bumper on a soft surface, like a blanket or a piece of cardboard, to prevent scratches.

Reassembly: Putting Everything Back Together

Great job! Now that the bumper is off, reassembly is just the reverse of removal. Here's a quick rundown to guide you:

1. Prepare the Bumper: If you're installing a new bumper, transfer any components like fog lights, parking sensors, and grilles from the old bumper to the new one.
2. Position the Bumper: Carefully align the bumper with the car's front end. Have a friend help you to make sure everything lines up properly.
3. Reconnect Wiring: Plug in all the wiring connectors for fog lights, parking sensors, etc.
4. Attach the Bumper: Gently push the bumper onto the car, ensuring it aligns with the mounting points. Start by aligning the sides and then the top.
5. Install Top Fasteners: Secure the bumper by reattaching the fasteners along the top edge (hood latch area and grille). Don't tighten them completely just yet.
6. Install Wheel Well Fasteners: Reinstall the fasteners inside the wheel wells, securing the bumper to the fenders.
7. Install Under-Bumper Fasteners: Crawl under the car and reinstall the bolts that secure the bumper to the undercarriage. Tighten all fasteners securely.
8. Reinstall Splash Shield: If applicable, reattach the splash shield under the bumper.
9. Lower the Car: Carefully lower the car from the jack stands, and remove the jack.
10. Reinstall Wheels: Reinstall your front wheels and lower your car. Remember to tighten the lug nuts in a star pattern.
11. Final Checks: Double-check that all fasteners are secure, and all wiring is connected. Give the bumper a gentle tug in a few places to make sure it's firmly attached.
12. Start the Car: Start the car and test all lights and sensors to ensure they are working properly.

Troubleshooting Tips

Even with a step-by-step guide, you might run into some snags. Here are a few troubleshooting tips:

• Stubborn Bolts: If a bolt is stuck, try applying penetrating oil and letting it sit for a few minutes. If that doesn't work, try using a breaker bar or impact wrench (use with caution).
• Broken Clips: Sometimes, plastic clips break. You can find replacements at most auto parts stores.
• Mismatched Parts: If you are installing a new bumper, make sure the replacement bumper is specifically designed for your IG37 sedan model year to ensure a perfect fit.
• Alignment Issues: If the bumper doesn’t align properly, double-check that all the fasteners are in the correct positions and that no clips are broken or missing. You might need to adjust the bumper slightly to get a perfect fit.
• Wiring Problems: If your lights or sensors don't work after reassembly, double-check all wiring connections. Make sure everything is plugged in securely and that you haven’t missed any connections.
• Missing Fasteners: If you are missing fasteners, make a list of what you need.

Safety Precautions and Final Thoughts

Remember, safety always comes first. Wear safety glasses to protect your eyes from debris, and always work in a well-ventilated area. If you're not comfortable with any step, don't hesitate to seek help from a professional mechanic. It's better to be safe than sorry!

Removing and reinstalling your IG37 sedan's front bumper can seem daunting, but by following these steps carefully, you can do it yourself. Take your time, stay organized, and don't be afraid to ask for help if you need it. Good luck, and happy wrenching! Your car will look great in no time.
