1984-1986 Toyota 4Runner Side Mirror: Finding the Right Chrome or Black Mirror
This guide covers common issues, part number differences, and how to find a compatible used mirror for your first-generation Toyota 4Runner.
- The most important compatibility factors are the finish (chrome vs. black) and ensuring you get a manual-adjust mirror, as power mirrors are extremely rare.
- Mirrors from 1984-1988 Toyota Pickups are a common and direct-fit alternative, which greatly expands your options for finding a good used part.
- The most frequent failure is the pivot becoming loose, causing the mirror to be 'floppy' and not hold its position while driving.
- Replacement is a very easy DIY job, requiring only basic hand tools and about 30 minutes.
Key Variants: Chrome vs. Black and Manual vs. Power
When replacing a side mirror on a first-generation 4Runner, the most important things to verify are the finish and adjustment type. These trucks came with a few different options from the factory.
- Black vs. Chrome Finish: The most common distinction is between a textured black plastic housing and a full chrome housing. The finish is purely cosmetic and often tied to the vehicle's trim level, with chrome mirrors typically found on higher-end SR5 models. When buying a replacement, it's important to choose the finish that matches your remaining mirror or your truck's original style.
- Manual vs. Power Adjustment: The vast majority of 1984-1986 4Runners were equipped with fully manual mirrors. However, some high-trim SR5 models came with very rare power-adjustable mirrors. Finding used OEM power mirrors is extremely difficult, and new replacements are unavailable. This guide focuses on the much more common manual mirrors.
Pro Tip: Mirrors from 1984-1988 Toyota Pickups often have the same mounting base and are a direct fit for the 4Runner. This significantly expands the available pool of used parts.
Symptoms of Failure
Because these mirrors are mechanical, failure symptoms are always related to physical wear or damage. Here’s what to look for:
- Loose or "Floppy" Mirror: This is the most common complaint. The pivot joint that holds the mirror head wears out over time, causing the mirror to vibrate or move out of position while driving, especially at highway speeds. Owners frequently complain that even a strong wind can knock them out of alignment.
- Cracked or Broken Glass: Impact from road debris, parking lot bumps, or trail obstacles can easily crack or shatter the mirror glass, which severely distorts the view and creates a safety hazard.
- Loose Mirror Assembly: The entire mirror housing may feel loose and shake while driving. This is usually caused by the three mounting bolts inside the door becoming loose over time due to vibration.
- Damaged Housing: The plastic or chrome housing can become cracked or broken from an impact, exposing internal components and compromising the mirror's stability.
Buying a Used 1984-1986 4Runner Side Mirror
A used OEM mirror is often a better choice than a cheap aftermarket alternative, as the original Toyota parts tend to have better quality glass and more durable housings that resist vibration. Here’s what to inspect before buying:
- Check the Finish: Decide if you need black or chrome and inspect the part for major cosmetic flaws. Look for deep scratches, cracks in the plastic, or significant pitting and rust on chrome models.
- Test the Pivot Joint: Hold the mounting base firmly and try to move the mirror head. It should move with smooth, firm resistance. If it's extremely stiff or, more likely, very loose and floppy, it will not hold its position when you drive.
- Inspect the Glass: Look for any cracks, chips, or dark "desilvering" spots, which indicate the reflective coating is failing.
- Verify the Mounting Base: The most critical step is to ensure the mounting base and bolt pattern match your vehicle. Compare it directly to your old mirror if possible. Remember that mirrors from a 1984-1988 Toyota Pickup are often identical.
Known Issues, TSBs, and Recalls
There are no official recalls or Technical Service Bulletins (TSBs) from Toyota or the NHTSA related to the side view mirrors on 1984-1986 4Runners. The primary known issue, widely reported by owners in forums, is the tendency for the mirror head's pivot to become loose over time, requiring frequent readjustment. Some owners attempt to fix this by disassembling the mirror and tightening the internal tension springs, but most find that replacement is the only permanent solution.
Replacement Guide & Difficulty
Replacing the side mirror on a first-generation 4Runner is a very simple job suitable for any DIYer.
- Difficulty: 1 out of 5
- Estimated Time: 15-30 minutes
- Tools Needed: Phillips head screwdriver or a small socket set, plastic trim removal tool (a flathead screwdriver wrapped in tape also works).
Step-by-Step Replacement
- Open the door and locate the small, triangular plastic trim piece on the inside of the door, directly opposite the mirror.
- Carefully pry this trim piece off. It is held in by clips.
- With the trim removed, you will see three screws or nuts holding the mirror assembly to the door.
- While supporting the mirror from the outside to prevent it from falling, remove the three fasteners.
- Pull the old mirror away from the door.
- Position the new mirror and hand-tighten the three fasteners.
- Once the mirror is secure, fully tighten the fasteners. Do not overtighten, as you could crack the plastic housing.
- Snap the interior trim piece back into place.

Frequently Asked Questions (FAQ)
Will a side mirror from a Toyota Pickup fit my 4Runner?
Yes, in most cases. Side mirrors from 1984 through 1988 Toyota Pickups are known to be a direct swap for the 1984-1986 4Runner. This is a great way to find a good quality used replacement. However, always visually compare the mounting base of the donor mirror to your original before purchasing.
How can I fix a floppy mirror that won't stay in place?
For a mirror assembly that is loose at the door, you can simply remove the interior trim panel and tighten the three mounting bolts. If the mirror glass itself is floppy at the pivot point, the internal tension mechanism is worn out. While some have attempted to disassemble and repair it, the most effective and lasting solution is to replace the entire mirror assembly.
Is it illegal to drive with a broken or missing side mirror?
In most states, you are legally required to have a functioning driver-side exterior mirror. A missing or broken passenger-side mirror may also result in a citation, depending on local laws. It is always a safety risk to drive with a compromised view, so replacement is highly recommended.
Can I just replace the mirror glass instead of the whole assembly?
Yes, if only the glass is cracked but the housing and pivot are in good condition, you can often buy just the replacement mirror glass. These are typically adhesive-backed and stick on over the old, broken glass. This is a cost-effective repair if the rest of the mirror is still functional.
