Universal Joint Guide for 1979-1986 Toyota Pickup
Everything you need to know before replacing the U-joints on your classic Toyota Pickup.
- Symptoms like clunking, vibrations, and squeaking are clear signs that your U-joints need inspection.
- For off-road use, a greasable U-joint is beneficial; for street driving, a stronger, maintenance-free sealed joint is often preferred.
- Spicer is a top-tier brand for strength, while Moog and SKF offer reliable OE-quality replacements.
- Replacing all U-joints on a driveshaft at the same time is recommended since they wear at a similar rate.
Is Your Toyota Pickup's U-Joint Failing?
A failing U-joint is a common issue on any truck, and these classic Toyota Pickups are no exception. Because they are a wear item, they will eventually need replacement. Ignoring the signs can lead to more than just an annoying noise; a complete failure can cause the driveshaft to disconnect, leaving you stranded and potentially causing significant damage to other parts of your truck. Listen and feel for these common symptoms:
🎬 Watch: How to tell if your U-joint is failing- Clunking Noise: A distinct “clunk” or ringing sound when you shift between drive and reverse is a classic sign of a worn U-joint with excessive play.
- Vibrations: A vibration that you can feel through the floor or seats, especially at highway speeds, often points to a failing U-joint. As the joint wears, it becomes unbalanced, causing the driveshaft to vibrate as it spins.
- Squeaking or Chirping: A rhythmic squeak that changes with your speed, often heard when first starting to move, usually means the U-joint has lost its grease and the internal needle bearings are running dry.
Choosing the Right Aftermarket U-Joint
Since these trucks are decades old, finding original Toyota (OEM) U-joints can be difficult and expensive. The good news is that the aftermarket offers a wide range of quality replacements. The main choice you'll face is between greasable and non-greasable (sealed) joints.
Greasable vs. Non-Greasable U-Joints
Greasable U-joints have a zerk fitting that allows you to pump fresh grease in, flushing out old grease, dirt, and water. 🎬 See how to grease your U-joints to stop clunks This is a major advantage if you frequently drive in mud, water, or dusty conditions. However, they require regular maintenance, and the grease channel can slightly weaken the joint's cross.
Non-greasable (sealed) U-joints are pre-filled with high-quality grease and sealed for life. They are generally considered stronger than greasable versions because the cross is solid metal. For a daily driver or a truck that sees mostly pavement, a sealed joint offers a maintenance-free, install-and-forget-it solution.
Aftermarket Brand Tiers
Not all aftermarket brands are created equal. Based on owner feedback and industry reputation, here’s how the available brands generally stack up for your Toyota Pickup:
- Premium (Heavy-Duty/Performance): Brands like Dana Spicer and Yukon Gear are highly regarded. Spicer is a well-known OEM supplier for many domestic trucks and has a reputation for durability. Their non-greasable joints are often recommended for their strength. Yukon Gear is known for high-performance drivetrain components.
- OE-Quality (Standard Replacement): Moog and SKF are solid, reliable choices for a daily-driven truck. They provide a good balance of quality and cost, often meeting or exceeding original factory specifications. Some users note that Moog's quality can be inconsistent depending on the specific part, but they are generally considered a safe bet.
- Economy (Budget-Friendly): GMB is often considered a budget-friendly option. Some forum users note that GMB is an OEM supplier for some Toyota models, making it a potentially good value.
A Note on "OEM" Parts
Some forum discussions suggest that the brand Matsuba is the original equipment manufacturer for Toyota U-joints of this era. If you can find Matsuba joints, they are considered an excellent, high-quality option, often at a lower price than dealer parts.
How Much Does a U-Joint Replacement Cost?

Frequently Asked Questions
How many U-joints does my 1979-1986 Toyota Pickup have?
A 2WD model typically has two U-joints on the rear driveshaft. A 4WD model has those two, plus additional joints on the front driveshaft (often three, including a double-cardan joint at the transfer case) and one on each front axle shaft. It's best to inspect your specific truck to confirm the configuration.
Can I replace a U-joint myself?
Yes, this is a common DIY job for truck owners with moderate mechanical skill. It requires basic hand tools to remove the driveshaft, plus a sturdy vise and a large socket or a U-joint press to remove the old joint and install the new one. Be careful not to damage the driveshaft yokes during the process.
🎬 Watch this step-by-step U-joint replacement walkthrough for classic ToyotasShould I replace all the U-joints at once?
If one U-joint has failed due to age and mileage, the others are likely not far behind. Since you will already have the driveshaft removed, it is good practice and cost-effective to replace all the U-joints on that shaft at the same time.
Do I need to get my driveshaft balanced after replacing the U-joints?
If the job is done correctly, balancing is not usually necessary. However, if you experience a new vibration after the replacement, the driveshaft may need to be professionally balanced. Always make match marks on the driveshaft and yokes before disassembly to ensure everything is reinstalled in its original orientation.
