Toyota T100 Universal Joint Replacement Guide (1993-1998)
Everything you need to know about diagnosing and replacing the U-joints on your 1993-1998 Toyota T100.
- Listen for squeaking at low speeds or clunking when shifting gears, as these are the earliest signs of U-joint failure.
- For best results, choose high-quality aftermarket brands like Spicer or GMB, which are often considered OEM-equivalent in quality.
- If your T100 has a two-piece driveshaft, inspect the center support bearing at the same time, as it can cause similar vibration symptoms.
- Mark the driveshaft's orientation before removal to ensure it is reinstalled correctly and avoid causing new vibrations.
Is Your T100's U-Joint Failing? Common Symptoms
A failing U-joint gives clear warning signs. The first thing you might notice is a rhythmic squeaking or clicking noise 🎬 Watch: How to tell if your U-joint is failing at low speeds, which often happens as the internal grease dries out. As the wear gets worse, you may hear a loud 'clunk' or 'ping' when you shift into Drive or Reverse. This sound is caused by excessive play in the joint. A more serious symptom is a vibration that you can feel through the floor of the truck, especially at highway speeds. Ignoring these signs can lead to complete failure, where the driveshaft can detach from the truck, causing a loss of control and significant damage.
Known Issues, Recalls, and Service Bulletins
Searches of the National Highway Traffic Safety Administration (NHTSA) database show no specific recalls or technical service bulletins (TSBs) for universal joints on the 1993-1998 Toyota T100. While other Toyota trucks have had customer support programs for similar issues, the T100 is not officially covered. Most U-joint failures on this truck are due to age and normal wear. However, owners report that vibrations can also be caused by a worn-out center support bearing 🎬 See how to install a new driveshaft carrier bearing on models with a two-piece driveshaft or by installing the driveshaft backward after service.
Choosing the Right Aftermarket U-Joint for Your T100
When replacing your U-joints, you have a choice between OEM from the dealer and several aftermarket brands. For a truck of this age, a high-quality aftermarket part can offer the best balance of price and performance.
Aftermarket Brand Quality Tiers
| Tier | Brands | Notes |
|---|---|---|
| Premium / OEM-Equivalent | Dana/Spicer, GMB | Spicer is highly recommended in owner forums and is a known OEM supplier for many truck manufacturers. Their non-greasable joints are considered stronger, while greasable ones allow for maintenance. GMB is a respected Japanese manufacturer, also believed to be an OEM supplier for Toyota, offering excellent quality. |
| Mid-Grade / Reputable Aftermarket | Moog, SKF | Moog is a popular brand, and their 'Super Strength' line is a decent choice. However, some users have reported inconsistent quality in recent years. SKF is another established bearing manufacturer, though there is less specific feedback from T100 owners. Both brands typically offer greasable joints. |
| Economy | Yukon Gear, Store Brands | These are the most affordable options. While functional, forums contain numerous accounts of cheaper, unbranded U-joints failing prematurely. They may be suitable for a temporary fix but are not recommended for long-term reliability. |
Pro Tip: Greasable vs. Non-Greasable. Non-greasable (sealed) U-joints are generally stronger because the cross isn't drilled for a grease fitting. However, greasable joints allow you to flush out water and dirt, which can extend their life, especially if you use your T100 off-road. If you choose greasable joints, be sure to grease them at every oil change.
Replacement Cost
The cost to replace your T100's U-joints depends on the parts you choose and whether you do the work yourself.

Frequently Asked Questions (FAQ)
How many U-joints does my Toyota T100 have?
It depends on your truck's configuration. A standard 2WD model with a one-piece driveshaft has two U-joints. 4WD models add a front driveshaft, which typically has two more joints. Some extended cab models use a two-piece rear driveshaft with a center support bearing, which will have three U-joints in the rear shaft, sometimes including a double-cardan joint near the center bearing that contains two U-joints close together.
Can I replace a U-joint myself?
Yes, this is a DIY-feasible job for someone with mechanical experience. You will need a good set of tools, including a socket set, snap ring pliers, and either a bench vise with large sockets or a dedicated U-joint press tool. 🎬 Watch: How to replace a U-joint without a hydraulic press The most difficult part is pressing the old joint out and the new one in without damaging the yokes on the driveshaft.
Do I need to get my driveshaft balanced after replacing the U-joints?
If you carefully mark the driveshaft's orientation to the axle and transmission yokes before removal and reinstall it in the same position, balancing is usually not necessary. However, if you experience a new vibration after the replacement, the driveshaft may be out of balance and should be taken to a specialty driveline shop.
What is a double-cardan joint?
Some T100s, particularly 4x4 models, have a double-cardan (or DC) joint in the driveshaft. It looks like two U-joints connected by a small centering yoke. This setup allows the driveshaft to operate at a steeper angle without vibrating. Rebuilding a DC joint is more complex than replacing a single U-joint and can be difficult.
