A Practical Guide to Universal Joints for the 1967 Triumph 2000
Address driveshaft vibrations and clunking noises by choosing the right replacement U-joint for your classic Triumph.
- Vibrations and clunking noises, especially when coasting, are the primary signs of a failing U-joint.
- Choose high-quality, greasable aftermarket U-joints from a brand like Dana Spicer for the best results.
- Due to the need for a press and the risk of improper installation, professional replacement is recommended if you are not an experienced mechanic.
- A failing U-joint is a safety issue that should be addressed immediately to prevent the driveshaft from detaching.
Signs of a Failing Universal Joint
Universal joints are wear items, especially on a classic car. Lack of regular greasing is a primary cause of failure. When a U-joint starts to fail, it gives clear warning signs. Ignoring them can lead to more significant damage or a dangerous breakdown if the joint breaks and the driveshaft detaches.
The most common symptom is a rhythmic ticking or a 'clunk' noise that changes with your speed. This sound is often more noticeable when you take your foot off the gas and let the car coast. You may also feel a vibration that starts at lower speeds and gets worse as you accelerate. If the noise is loudest when you are turning, it can help pinpoint a failing U-joint in one of the rear half-shafts. For example, a ticking noise on a right-hand turn often points to a bad U-joint on the right side.
Choosing the Right Aftermarket U-Joint
Original equipment (OEM) U-joints for a 1967 vehicle are no longer available. You will be choosing from aftermarket brands. For a classic like the Triumph 2000, selecting a quality, greasable U-joint is highly recommended for longevity. Non-greasable, or sealed, joints are available but take away your ability to perform essential maintenance.
| Brand Tier | Brands | General Assessment |
|---|---|---|
| Premium Quality | Dana Spicer Chassis | Widely considered the gold standard by mechanics and enthusiasts. Spicer is known for making durable, high-quality parts that often meet or exceed original specifications. They are a top recommendation in many forums. |
| Standard Quality | Moog | A well-known brand that has historically been a go-to for suspension and driveline parts. However, some users report mixed experiences in recent years, with concerns about inconsistent quality. One Triumph owner noted issues with aftermarket circlips from a Moog kit being too thick, causing the joint to be too stiff. |
| Economy | GMB | GMB is generally known as a budget-friendly option. While they can be a cost-effective choice, they are not typically placed in the same high-quality category as Dana Spicer by enthusiasts. |
A Note on Installation
Replacing U-joints requires pressing the old ones out and the new ones in. This is often done with a large bench vise or a hydraulic press. It is critical that the new joint moves freely in all directions after installation. If it feels stiff, the bearing caps may have been pressed in too far, or the retaining circlips may be the wrong thickness, causing the joint to bind. If you lack the tools or experience, this job is best left to a professional mechanic familiar with classic cars.
Frequently Asked Questions (FAQ)
How many U-joints does my 1967 Triumph 2000 have?
Your Triumph 2000 has four main U-joints in the driveline: two on the central propshaft and one on each of the two rear half-shafts, for a total of four.
Should I buy greasable or sealed U-joints?
For a classic car, greasable U-joints are highly recommended. They allow you to flush out old, contaminated grease and add new grease as part of your regular maintenance schedule. This can significantly extend the life of the part.
What happens if I don't replace a bad U-joint?
A worn U-joint will get progressively worse, causing more noise and vibration. Eventually, it can fail completely. If this happens while driving, the driveshaft can detach from the car, causing a loss of power and potentially severe damage to the underside of your vehicle. It is a serious safety risk.
Can I replace just one U-joint?
Yes, you can replace only the failing joint. However, if one has failed due to age and mileage, the others are likely not far behind. It is common practice to replace them in pairs (e.g., both on the propshaft, or both on a single half-shaft) or all at once for peace of mind.
