1985-1990 Astro & Safari Wheel Covers: Finding Your Style and Preventing Fly-Offs
Your definitive guide to identifying, inspecting, and securely installing the correct factory wheel covers for your first-generation Chevrolet Astro or GMC Safari.
- The most common failure is the cover falling off due to old, brittle retaining clips on the back.
- When buying a used cover, inspecting the back for intact clips is more important than the cosmetic condition of the front.
- Wheel covers from the 1985-1990 GMC Safari and Chevy Astro are interchangeable; only the center logo differs.
- Installation is a simple, tool-free, snap-on process. Always align the cover's notch with the tire's valve stem.
Symptoms of a Failing or Missing Wheel Cover
Because a wheel cover is not a mechanical part, its failure symptoms are straightforward and usually obvious. The most common issues are cosmetic or audible.
- Rattling or Clicking Noises: A rattling, clicking, or scraping sound from the wheel area while driving often indicates a loose wheel cover. This is typically caused by broken or weakened retaining clips on the back of the cover, allowing it to vibrate against the steel wheel.
- Visible Damage: Cracks, deep scratches (curb rash), and discoloration are common signs of an aging or damaged wheel cover. While this is purely cosmetic, significant cracks can weaken the cover's structure, making it more likely to fall off.
- Missing Cover: The most definitive symptom is the wheel cover being gone entirely. This exposes the plain, often rusty, steel wheel underneath and leaves the lug nuts and hub exposed to the elements.
Pro Tip: If you hear a rattling noise, pull over and check your wheel covers immediately. Securing a loose cover with zip ties through the slots can be a good temporary fix to prevent it from flying off and becoming a road hazard until you can replace it.
Identifying Your 1985-1990 Wheel Cover Style
Chevrolet and GMC offered a few different wheel options for the first-generation Astro and Safari, so it's important to identify which cover you need. The most reliable way is to find the part number stamped on the back of one of your existing covers.
| Part Number | Vehicle | Description | Notes |
|---|---|---|---|
| 14074879 | Chevrolet Astro | 15-inch full-face "Deluxe" wheel cover. | This was a common cover on mid-level trims. It features a separate, smaller center cap with the Chevrolet bowtie logo. |
| 15521914 | GMC Safari | 15-inch full-face wheel cover. | This is the GMC equivalent of the 14074879 cover and is interchangeable with it, aside from the logo. |
| 14074883 | Chevrolet Astro | Center cap insert ONLY. | This is not the full wheel cover. It is the small, removable center cap for the 14074879 cover. If just your logo cap is missing, this is the part you need. |
| N/A | Astro / Safari | "Dog Dish" or Rally Caps | Base models and some S10 trucks of the era used smaller hubcaps that only covered the center of the wheel, leaving the lug nuts and outer steel rim exposed. |
Buying a Used 1985-1990 Astro/Safari Wheel Cover
Given the age of these vans, a used OEM wheel cover is often the best and most affordable option. New old stock (NOS) parts are rare and expensive, while modern aftermarket replacements may not match the original look or quality. Here’s what to inspect before buying a used cover.
The Ultimate Inspection Checklist:
- Flip It Over: The back of the cover is more important than the front. Look for the metal retention ring that runs along the circumference. Ensure it is not excessively rusted or broken.
- Check Every Clip: This is the most critical step. These wheel covers are held on by a series of metal or plastic clips that the retention ring puts pressure on. Carefully inspect every single clip. If even one or two are cracked or missing, the cover will not hold securely and is likely to fall off. Do not buy a cover with broken clips.
- Look for Hairline Cracks: Examine the front and back surfaces closely, especially around the outer edge and the center. Small, hairline cracks can grow over time from vibration and temperature changes, eventually leading to a piece breaking off or total failure.
- Verify the Part Number: If possible, match the part number on the back of the used cover to your existing one to guarantee a perfect match in style and fit.
- Assess Cosmetic Condition: Scuffs and minor scratches are normal for a used part. Decide what level of cosmetic wear you are comfortable with. Deep curb rash or heavy fading may be difficult to repair.
Installation Guide (Snap-On Style)
Installing these wheel covers is a simple task that requires no special tools.
- Difficulty: 1 out of 5
- Estimated Time: 2 minutes per wheel
- Tools Needed: Rubber mallet (optional), clean cloth
Step-by-Step Instructions:
- Clean the Wheel: Wipe down the steel wheel to remove any built-up brake dust or grime. This ensures the cover sits flush.
- Align the Valve Stem: Find the small cutout or indentation on the edge of the wheel cover. Align this opening with the tire's air valve stem on the wheel. This is essential for checking your tire pressure later.
- Secure the Cover: Starting at the top, press the cover onto the wheel. Give it a firm tap with the heel of your hand. Work your way around the cover, tapping it into place until you hear and feel it snap securely onto the wheel rim. A rubber mallet can be used for gentle, even taps.
- Check for Security: Once installed, grab the edges of the wheel cover and try to wiggle it. It should feel tight and secure with no rattling or movement.
Warning: Never use a metal hammer to install a wheel cover, as it will easily crack or shatter the plastic.

Known Issues, Recalls, and Service Bulletins
There are no recalls or Technical Service Bulletins (TSBs) issued by the NHTSA or General Motors specifically related to the wheel covers on the 1985-1990 Chevrolet Astro or GMC Safari. While other recalls exist for this vehicle generation concerning items like seat belts and lighting, the wheel covers were never subject to a safety campaign. The primary known issue is the tendency for the plastic retaining clips to become brittle with age, leading to the cover falling off.
Frequently Asked Questions (FAQ)
Will a wheel cover from a GMC Safari fit my Chevrolet Astro?
Yes, the wheel covers for the 1985-1990 GMC Safari (Part No. 15521914) and Chevrolet Astro (Part No. 14074879) are physically identical and interchangeable. The only difference is the logo on the center cap.
How can I prevent my wheel cover from falling off?
The best prevention is ensuring all retaining clips are intact upon installation. For extra security, some owners place a few black zip ties through the slots in the wheel cover and around a spoke of the steel wheel behind it. This is a cheap and effective way to keep the cover attached even if the clips fail.
Are cheap aftermarket wheel covers a good idea?
Aftermarket covers can be a budget-friendly solution, especially if you need a full set. However, they are often made from thinner, more brittle plastic than OEM parts and may not have as secure a fit. For a single replacement, a used OEM cover is often a better value and guarantees a perfect match to the remaining originals.
What's the difference between a hubcap and a wheel cover?
Though the terms are often used interchangeably, a 'hubcap' technically only covers the central hub of the wheel (like a 'dog dish' cap). A 'wheel cover' is typically larger and covers the entire face of the wheel. The main factory option for the 1985-1990 Astro was a full wheel cover.
