Toyota Crown Universal Joint Guide (1964-1972): Driveline Health and Replacement
Keep your classic 1964-1972 Toyota Crown running smoothly by understanding, diagnosing, and replacing your universal joints.
- A clunking noise when shifting gears or a vibration at highway speeds are the most common signs of a failing U-joint on your Crown.
- Do not ignore symptoms. A complete U-joint failure can be extremely dangerous and cause extensive damage to your vehicle.
- New OEM parts are unavailable; high-quality aftermarket brands like Dana Spicer or GMB are the recommended choice for durability and value.
- For maximum reliability, choose a non-greaseable (sealed) U-joint from a reputable brand, as they are stronger and require no maintenance.
Understanding the Universal Joint in Your Classic Crown
The universal joint, or U-joint, is a small but mighty part of your 1964-1972 Toyota Crown’s driveline. It’s a cross-shaped component with a bearing cap at each of the four ends. These bearings allow the driveshaft to flex and articulate as the rear axle moves with the road's surface, ensuring power is constantly delivered to the wheels. Over many decades and miles, these joints wear out from normal use, lack of lubrication, or exposure to the elements. Since your Crown is a classic car, it's very likely the original U-joints have been replaced at least once, or are due for inspection.
Symptoms of a Failing U-Joint
A bad U-joint will almost always give you warning signs. Listening to your car is key. Here are the most common symptoms to watch for:
- "Clunk" Noise: A loud clunk or ping when you shift from Park into Drive or Reverse is a classic sign. This sound is caused by excessive play in a worn-out joint. You might also hear it when you accelerate or decelerate.
- Vibrations While Driving: A vibration that you can feel through the floor or seats, which often gets worse as you increase speed, points to a failing U-joint. This happens because the worn joint has thrown the driveshaft out of balance.
- Squeaking or Chirping: A rhythmic squeaking noise that increases with your speed is often a sign of a dry, unlubricated U-joint bearing. The needle bearings inside the cap are failing due to lack of grease.
- Visible Rust or Damage: If you look under the car, you might see rust dust around the U-joint's bearing caps. This indicates the seals have failed and moisture has gotten inside, destroying the bearings.
Critical Failure is Dangerous
If a U-joint breaks completely while driving, the driveshaft can detach from the car. This can cause it to dig into the pavement, potentially flipping the vehicle, or flail around and severely damage your transmission, exhaust, and the underside of your Crown. Do not ignore the symptoms of a bad U-joint.
Choosing the Right Aftermarket U-Joint
For a vehicle from the 1964-1972 era, finding new original equipment (OEM) parts is nearly impossible. The good news is that several aftermarket companies produce high-quality U-joints that meet or exceed original specifications. The choice often comes down to a balance of budget and desired longevity.
Brand Quality Tiers
Based on owner experiences and mechanic recommendations, aftermarket brands for your Crown can be grouped into tiers:
- Top Tier (Professional Grade): Dana Spicer is widely regarded as a top-tier brand, often used as an OEM supplier for American manufacturers and known for its strength and durability. Many consider their non-greaseable joints to be the strongest and longest-lasting option. If you want the best available part, Spicer is a solid choice.
- Quality OEM-Equivalent: GMB is a Japanese manufacturer and is considered a high-quality brand, sometimes supplying parts directly to Toyota. For a classic Toyota, GMB offers a great combination of proper fit, quality, and value. SKF is another well-respected brand known for its bearings and driveline components, offering a quality alternative.
- Standard/Economy: Moog has a mixed reputation in recent years. While once considered a top aftermarket brand, some users report a decline in quality, though others still use them without issue. They can be a suitable budget-friendly option, but may not have the longevity of the top-tier brands.
Greaseable vs. Non-Greaseable
You will see options for both greaseable (with a zerk fitting) and non-greaseable (sealed) U-joints. Non-greaseable joints are often considered stronger because the cross isn't drilled out for grease channels. They are filled with high-quality grease at the factory and sealed for life. Greaseable joints can last a very long time, but only if they are regularly maintained with the correct grease. For a classic car that may not be driven daily, a high-quality, non-greaseable joint from a brand like Spicer is often the most reliable, install-and-forget option.
Estimated Costs
| Part/Service | Estimated Cost |
|---|---|
| Aftermarket Universal Joint | $18 - $66 per joint |
| Shop Labor (per joint) | $120 - $250 |
| Total Professional Replacement (1 Joint) | $140 - $315 |
Costs are estimates and can vary based on your location, the specific part chosen, and the condition of your vehicle. It is often recommended to replace U-joints in pairs.
Frequently Asked Questions (FAQ)
Are there any recalls for 1964-1972 Crown U-joints?
No, there are no active recalls or specific Technical Service Bulletins (TSBs) from the NHTSA regarding universal joints for the 1964-1972 Toyota Crown. Any issues that arise are due to the age and wear of the components.
Can I replace a U-joint myself?
Yes, this is a DIY-feasible job for someone with moderate mechanical skill and the right tools. It involves safely lifting the vehicle, removing the driveshaft, and using a press or a combination of sockets and a hammer to remove the old joint and install the new one. However, improper installation can cause vibrations, so if you are not confident, it is best to have a professional do the work.
Should I replace both U-joints at the same time?
It is highly recommended. If one U-joint has failed due to age and mileage, the other is likely not far behind. Replacing them both at the same time saves you from having to do the job again in the near future and ensures the entire driveshaft is in good condition.
What happens if I don't replace a bad U-joint?
Ignoring a bad U-joint will lead to a complete failure. The vibrations and noise will get progressively worse until the joint breaks. When it breaks, the driveshaft will disconnect, leaving you stranded and likely causing hundreds or thousands of dollars in damage to other parts of your car.
