Universal Joint Guide for the 1990-1995 Toyota 4Runner
Understand the symptoms of a bad U-joint and how to choose the right replacement for your 2nd Gen 4Runner.
- A clunking noise when shifting or a vibration at speed are the most common signs of a failing U-joint.
- Do not ignore symptoms; a complete failure can cause the driveshaft to fall, leading to a loss of control and expensive damage.
- For aftermarket parts, Dana Spicer is a top-tier brand, while SKF and Moog offer reliable, OEM-quality performance.
- Replacing U-joints is a manageable DIY project, but it can be difficult without a press or a large vise.
Is Your 4Runner's U-Joint Failing?
A failing universal joint is a common issue on older trucks like the 1990-1995 Toyota 4Runner. Because they are constantly moving and under a lot of stress, they wear out over time. Ignoring the signs can lead to a complete failure where the driveshaft can separate from the vehicle, causing major damage and a dangerous loss of control. It's a repair you shouldn't put off.
Symptoms of a Bad U-Joint
Listen and feel for these common signs of a worn-out U-joint:
- Clunking Noise: A distinct "clunk" or "ping" when you shift from park into drive or reverse is a classic symptom. This happens because the worn joint has extra space, and the driveshaft slaps into place when power is applied.
- Vibration: You may feel a vibration throughout the vehicle, especially at highway speeds. This is because the worn U-joint is causing the driveshaft to spin out of balance. It's a different feeling than a tire imbalance and often gets worse during acceleration.
- Squeaking or Chirping: A steady, rotational squeak that changes with your speed points to a U-joint that has lost its grease and is drying out. This is often the first sign of a problem. 🎬 Watch: Hear and see these common U-joint failure symptoms
Choosing the Right Aftermarket U-Joint
For the 2nd Generation 4Runner, you have several good aftermarket options. The original factory U-joints were high quality, but modern aftermarket parts from reputable brands offer excellent performance, often at a better price. The main choice you'll make is between a greasable and a non-greasable (sealed) joint.
Pro Tip: Greasable U-joints have a small fitting (a zerk) that allows you to add fresh grease periodically. This can extend their life significantly if you perform regular maintenance. Sealed joints are maintenance-free but must be replaced when they wear out. For most owners, a quality sealed joint is a great "fit and forget" option. Off-roaders or those who prefer hands-on maintenance may prefer greasable joints.
Aftermarket Brand Tiers
Based on owner feedback and mechanic consensus, here’s how the available brands generally stack up for your 4Runner:
- Top Tier (Heavy-Duty & Off-Road): Dana Spicer is widely regarded as a top-tier choice, known for strength and durability. Many consider them the gold standard, even for Toyota applications. They are an excellent choice if you use your 4Runner for off-roading or towing.
- OEM Quality (Reliable Replacements): SKF and Moog are strong, reliable brands that are considered OEM-quality or better. They are a solid choice for a daily driver and will restore original performance. While Moog has a strong historical reputation, some users note that quality can be inconsistent depending on the specific part, but they remain a popular choice.
- Standard/Budget (Good Value): GMB is often a budget-friendly option that provides good value for the price. It's a suitable replacement for a daily-driven 4Runner under normal conditions.
- Specialty: Yukon Gear & Axle is well-known in the differential and axle world and offers quality driveline components, often geared toward performance and off-road use.
| Part Type | Estimated Cost (Per Joint) |
|---|---|
| New Aftermarket | $21.13 - $65.69 |
| New OEM | $60 - $80 |
| Shop Labor | $150 - $300 |
Note: Your 4Runner has multiple U-joints. A 4WD model has U-joints on both the front and rear driveshafts. It is common practice to replace all U-joints on a single driveshaft at the same time.
Frequently Asked Questions
How many U-joints does my 1990-1995 4Runner have?
A 2WD model has two U-joints on the rear driveshaft. A 4WD model typically has two on the rear driveshaft and two on the front driveshaft. Some shafts may also have a double-cardan joint near the transfer case, which contains two U-joints in close proximity.
🎬 Watch this detailed walkthrough for replacing Toyota-specific driveshaft jointsCan I replace the U-joints myself?
Yes, this is a DIY-feasible job for someone with moderate mechanical experience. It requires removing the driveshaft (be sure to mark its orientation first), and then using a large vise, a ball joint press, or a hammer and sockets to press the old joints out and the new ones in. It can be a tough job if the old joints are rusted in place.
🎬 See how to replace a U-joint using simple hand toolsShould I choose greasable or sealed U-joints?
If you are diligent about maintenance and want the longest possible lifespan, greasable joints are a great option. You'll need to grease them with an NLGI No. 2 grease every 5,000 to 15,000 miles. If you prefer a maintenance-free solution, high-quality sealed U-joints from a brand like Spicer or SKF are an excellent and reliable choice.
Were there any recalls for the U-joints on this 4Runner?
No, searches of the NHTSA database did not find any recalls specifically for universal joints on the 1990-1995 Toyota 4Runner. A Customer Support Program was issued for later model years for drivetrain vibration, but it does not apply to this generation.
