1999-2000 Nissan Frontier Tail Finish Panel: A Guide to Finishes and Trim Levels
This guide helps you choose the correct used OEM tail finish panel by explaining the critical differences between XE, SE, and Desert Runner trims.
- Compatibility is critical: You must match the part number to your Frontier's trim (XE, SE, Desert Runner) and bed configuration.
- Inspect used parts for broken mounting tabs; this is the most common reason for a poor fit and rattling.
- Most new OEM panels are discontinued, making used OEM parts the primary and often best-fitting option.
- Installation is a simple DIY task requiring basic hand tools and takes less than an hour.
Variant Differences: Getting the Right Panel for Your Frontier
For the 1999-2000 Nissan Frontier, the tail finish panel is not a one-size-fits-all part. Ordering the wrong one is a common mistake. Compatibility depends entirely on your truck's trim package (XE, SE, or Desert Runner) and configuration. Using the wrong panel can result in a poor fit or a mismatched appearance. Always verify your truck's details before purchasing.
Warning: Several of these original OEM part numbers have been discontinued by Nissan, making the used OEM market the primary source for these panels. Double-check part numbers and photos to ensure a match.
| Part Number | Trim Level & Configuration | Known Details |
|---|---|---|
| 90810-7B400 | XE | Fits XE models, including those with a short bed or crew cab with a short bed. This is one of the more common base model panels. |
| 90810-7B405 | SE | Specifically for the higher-trim SE models, often on the crew cab with a short bed. This part is confirmed to be different from the XE version and is now discontinued. |
| 90810-9Z300 / 90810-9Z310 | Desert Runner / XE | Fits King Cab models and Crew Cabs with a long bed. It is specifically associated with the Desert Runner trim package. The Desert Runner was a unique 2WD model that used the taller 4WD chassis and suspension. This part is also listed as discontinued. |
| 90810-7BA0C | Varies | This part number also exists but has less specific application data available in public catalogs. It's crucial to verify its fitment against a vehicle's VIN. |
Symptoms of a Failing Tail Finish Panel
Failure of this part is purely cosmetic or physical. It will not trigger any warning lights or affect the truck's drivability.
- Cracked or Chipped Plastic: Impacts from loading cargo or minor rear-end bumps can easily crack the aged plastic.
- Faded or Peeling Finish: After decades of sun exposure, the original finish—whether solid black or the silver/gray gradient—can fade, peel, or become chalky.
- Loose Fit or Rattling: The panel is held on by plastic clips and screws. Over time, these clips can become brittle and break, causing the panel to feel loose, vibrate, or rattle when driving or closing the tailgate.
- Missing Decals: Some owners report that the large 'Nissan Frontier' decal applied to the panel can peel off over time due to adhesive failure.
Buying a Used 1999-2000 Frontier Tail Finish Panel
Since most new OEM panels are discontinued, buying a quality used part is the best option. Here’s what to look for:
- Verify the Part Number: This is the most critical step. Match the part number from your original panel or confirm the correct number for your truck's VIN with a dealership. The differences between XE, SE, and Desert Runner panels are significant.
- Inspect All Mounting Tabs: Carefully flip the panel over and inspect every mounting tab and clip location. These are the most common failure points. Even one or two broken tabs can cause a poor fit and lead to rattling. Ensure none are cracked or missing.
- Check for Cracks: Examine the entire surface, especially around the handle opening and corners, for hairline cracks. A small crack can grow quickly, especially in cold weather.
- Assess the Finish: Look at photos taken in good light. Is the finish faded, scratched, or peeling? While a used part won't be perfect, you want one that is in good cosmetic condition to avoid the cost of refinishing it.
- Why Used OEM is Better: For a cosmetic part like this, OEM (Original Equipment Manufacturer) is almost always superior to aftermarket. A used OEM panel is guaranteed to fit correctly, use the original factory-grade plastic, and match the original color and texture, which aftermarket parts often fail to replicate perfectly.
Installation Guide
Replacing the tail finish panel is a straightforward DIY job. The process involves removing the tailgate handle bezel to access the mounting hardware.
- Difficulty: 2 out of 5
- Time: 30-45 minutes
- Tools Needed: Phillips screwdriver, flathead screwdriver, 10mm socket with extension and ratchet.
Step-by-Step Process:
- Open the tailgate. Remove the screws holding the inner access panel on the top edge of the tailgate.
- Pry the access panel off to reveal the inside of the tailgate and the back of the handle mechanism.
- Using a 10mm socket, locate and remove the two nuts that hold the tailgate handle and finish panel assembly to the tailgate.
- With the nuts removed, the handle and finish panel can be carefully pried away from the outside of the tailgate. It is held in by several plastic clips, so work your way around the perimeter with a trim tool or a screwdriver wrapped in tape to avoid scratching the paint.
- Once the old panel is off, clean the area on the tailgate.
- Position the new panel, align the clips with their holes, and press it firmly into place until the clips snap in.
- Reinstall the 10mm nuts from inside the tailgate, being careful not to overtighten and crack the plastic.
- Replace the inner access panel and its screws.
Pro Tip: Before installing the replacement panel, it's a good idea to inspect and lubricate the tailgate latch mechanism and rods while you have easy access to them.

| Shop Labor | $50 - $100 | Most auto body or repair shops can perform the replacement in under an hour. |
Known Issues, Recalls, and Service Bulletins

Frequently Asked Questions (FAQ)
Will a tail finish panel from a Desert Runner fit on my XE model?
Not perfectly. The part numbers are different, indicating variations in fitment based on cab and bed configuration. While it might be physically possible to mount it, the alignment with the tailgate's body lines may be incorrect. It is always best to match the part number to your truck's specific trim and build.
How can I fix a rattling tailgate panel?
A rattling noise is almost always caused by broken or loose plastic mounting clips. The best solution is to remove the panel following the installation guide above and replace any broken clips. If the mounting points on the panel itself are broken, you may need to replace the entire panel.
Can I just paint my faded tail finish panel?
Yes. A faded or scratched panel can be refinished. For best results, the panel should be removed from the truck, thoroughly cleaned, and sanded. Use a plastic adhesion promoter before applying automotive trim paint to ensure the new finish lasts.
What holds the tail finish panel onto the truck?
The panel is secured by a combination of plastic clips around its perimeter and two 10mm nuts that are part of the tailgate handle assembly, which are accessed from inside the tailgate.
