1998-2002 Mazda 626 Wheel Covers: A Guide to the 14-Inch and 15-Inch Variants

Identifying Your 1998-2002 Mazda 626 Wheel Cover

The most critical step in replacing a wheel cover for a 1998-2002 Mazda 626 is identifying the correct size. These vehicles came from the factory with two different sizes of steel wheels, and the corresponding wheel covers are not interchangeable. Installing the wrong size will result in it either not fitting or falling off while driving.

14-Inch, 7-Spoke Wheel Cover

This was the more common wheel cover, typically found on models with the 2.0L 4-cylinder engine, such as the DX and LX trims. It features a simple, clean 7-spoke design.

• Size: 14 inches
• Style: 7 Spokes
• Associated Vehicles: 1998-2002 Mazda 626, primarily 2.0L models (DX, LX)
• Known OEM Part Numbers: GD7A-37-170, GD7A-37-170A

15-Inch, Multi-Spoke Wheel Cover

This wheel cover was designed for the larger steel wheels often equipped on higher trim levels, particularly those with the 2.5L V6 engine like the LX-V6 and ES models. It has a more complex, multi-spoke (often 10 or more spokes) design.

• Size: 15 inches
• Style: Multi-Spoke
• Associated Vehicles: 1998-2002 Mazda 626, primarily 2.5L V6 models (LX, ES)
• Known OEM Part Numbers: GD7E-37-170, GD7E37170

Symptoms of a Failing or Missing Wheel Cover

Failure for a wheel cover is typically straightforward and does not affect the vehicle's drivability.

• Rattling or Clicking Noises: A rattling, clicking, or creaking sound from one of the wheels, especially at low speeds, often indicates a loose wheel cover. This is usually caused by one or more broken plastic mounting clips on the back, or a bent metal retaining ring.
• Visible Damage: Cracks, deep scuffs from hitting a curb, and peeling or faded paint are common cosmetic issues. While minor scuffs are normal, significant cracks can compromise the cover's structure and lead to it breaking apart or falling off.
• Missing Wheel Cover: The most obvious symptom is the cover being gone entirely. This can happen after hitting a pothole, from fatigued mounting clips, or due to theft.

Buying a Used 1998-2002 Mazda 626 Wheel Cover

Buying a used OEM wheel cover is an excellent way to save money while getting a part that fits correctly. Here’s what to look for.

Step 1: Verify Size and Part Number

First, confirm your wheel size (14" or 15") from your tire's sidewall. If possible, match the part number stamped on the back of your old wheel cover to the used one you are considering. The 14-inch version is typically GD7A-37-170(A) and the 15-inch is GD7E-37-170.

Step 2: Inspect the Mounting System

Turn the wheel cover over and carefully inspect all the plastic clips around the perimeter. They should all be present and free of cracks. Test their flexibility gently; they should have some give but not be brittle. Also, ensure the metal retaining ring is present, properly seated in its groove, and not excessively rusted or bent. Even one broken clip can cause a rattle and will eventually lead to the cover falling off.

Step 3: Assess Cosmetic Condition

Check for physical damage. Minor curb rash (scuffs on the outer edge) is common and acceptable for a used part. However, look closely for cracks, especially those starting from the center or lug nut openings and spreading outward. A cracked cover is structurally weak. Faded paint is purely cosmetic, but deep gouges or peeling clear coat may be a concern if appearance is a high priority.

Why Used OEM is a Smart Choice

Original Equipment Manufacturer (OEM) wheel covers are made by Mazda and are designed for a perfect fit. The plastic is generally more durable and flexible than that used in cheap, new aftermarket covers. Aftermarket covers can sometimes have a slightly different color, a less secure fit leading to rattles, or paint that peels much faster than the original. A good-condition used OEM cover often provides better long-term value and fitment than a brand-new aftermarket alternative.

Installation Guide

• Difficulty: 1 out of 5 (Very Easy)
• Time: Less than 5 minutes
• Tools: None required. A rag and a rubber mallet can be helpful but are not necessary.

Procedure:

1. Align the Valve Stem: Look for an indentation or cutout on the edge of the wheel cover. This opening must be aligned with the tire's valve stem (the small nozzle used to add air).
2. Position the Cover: Place the cover over the steel wheel, ensuring it is centered.
3. Apply Even Pressure: Using the palms of your hands, give the cover a firm tap near one edge to seat a few clips. Move around the cover, applying firm, even pressure to snap the remaining clips into place. You should hear and feel them click as they secure to the wheel.
4. Final Check: Gently try to pull on the edges of the cover to ensure it is securely attached and does not wobble.

Known Issues, Recalls, and Service Bulletins

There are no official recalls or Technical Service Bulletins (TSBs) from Mazda or the NHTSA specifically for the wheel covers on the 1998-2002 Mazda 626. The most common owner-reported issue is the covers falling off, which is almost always due to age-related brittleness of the plastic mounting clips, damage from curb impacts, or improper installation.
