A Practical Guide to Universal Joints for the 1973-1981 Buick Regal
Understand the symptoms of a failing U-joint and how to choose the best aftermarket replacement for your classic Regal.
- A clunk when shifting into gear or a vibration at speed are the most common signs of a failing U-joint.
- It is highly recommended to replace both U-joints at the same time, even if only one shows signs of failure.
- For reliability, choose premium non-greasable brands like Dana Spicer or SKF, or greasable ones like Moog if you perform regular maintenance.
- No recalls or specific TSBs were found for U-joint issues on the 1973-1981 Buick Regal.
Is Your Buick Regal's U-Joint Failing?
A worn-out universal joint will give you clear warning signs. Because this part connects the driveshaft to the rest of the car, you will usually hear or feel the symptoms from the center or rear of the vehicle. Ignoring these signs can lead to a complete failure where the driveshaft detaches, causing a loss of power and potentially severe damage to the underside of your car.
Key Symptoms of a Bad U-Joint:
- Clunking Noise: A loud "clunk" or "bang" when you shift into Drive or Reverse is a classic sign of a worn U-joint. This sound comes from excessive play in the joint.
- Vibrations: You might feel a vibration throughout the car that gets worse with speed. This happens when the worn joint throws the driveshaft out of balance.
- Squeaking or Chirping: A rhythmic squeaking sound that changes with your speed often points to a U-joint that has lost its grease and is running dry.
- Visible Signs: If you inspect the U-joints, you might see rust-colored dust around the bearing caps, which indicates the internal needle bearings are failing.
Pro Tip: Inspecting Your U-Joints
You can check for a bad U-joint yourself. With the car securely parked and the transmission in neutral (chock the wheels for safety), get underneath and try to twist the driveshaft by hand. If you feel any looseness or play in the U-joints, they are worn and need replacement.
Choosing the Right Aftermarket U-Joint
Since new OEM parts for a 1973-1981 Regal are generally not available, the aftermarket is your go-to source. The quality of aftermarket U-joints is often as good or even better than the original parts. Brands like Dana/Spicer and Moog are highly regarded in forums for classic GM cars. Aftermarket U-joints come in two main types: greasable and non-greasable (sealed).
- Greasable U-Joints: These have a zerk fitting that allows you to add fresh grease periodically. This can extend their life if you perform regular maintenance.
- Non-Greasable (Sealed) U-Joints: These are sealed from the factory and require no maintenance. Many people prefer these because they are stronger (the cross isn't drilled for a grease channel) and often last a very long time, similar to the original factory joints.
Brand Quality Tiers
Based on owner feedback and general reputation, here is a breakdown of the available brands:
- Premium Tier (High Quality & Durability): Dana Spicer Chassis and Moog are consistently recommended as top choices. Spicer was an original equipment supplier to GM, and their parts are known for durability. Moog is also a very popular and trusted brand with a strong warranty. SKF is another excellent choice, known for high-quality bearings.
- Performance Tier (Heavy Duty): Yukon Gear & Axle specializes in high-performance and heavy-duty driveline components. While potentially overkill for a standard Regal, they are an excellent, high-quality option if you have a modified engine or drive your car hard.
- Standard Tier (Good Value): GMB is generally considered a reliable budget-friendly option. While some mechanics prefer premium brands, GMB can be a good choice for a daily driver under normal conditions.
A Note on Greasable Joints
While greasable U-joints can last a long time with proper care, failing to grease them regularly will cause them to fail much faster than a sealed joint. If you don't plan on doing regular maintenance, a non-greasable joint from a premium brand like Spicer or SKF is often the more reliable choice.
Typical Replacement Costs
The cost to replace U-joints can vary depending on labor rates in your area and whether you do the work yourself.
| Item | Estimated Cost |
|---|---|
| Aftermarket U-Joint (Single) | $21 - $108 |
| Shop Labor (for two joints) | $150 - $350 |
| Total Professional Replacement | $200 - $450 |
Frequently Asked Questions
How many U-joints does my 1973-1981 Buick Regal have?
Most 1973-1981 Buick Regals have a one-piece driveshaft with two universal joints: one at the transmission end and one at the rear axle.
Should I replace both U-joints at the same time?
Yes, it is highly recommended. If one U-joint has failed due to age and mileage, the other is likely not far behind. Replacing both at the same time saves you from having to do the job twice.
Is replacing a U-joint a difficult job?
It is a moderately difficult job for a DIY mechanic. The driveshaft must be removed, and pressing the old joints out and the new ones in requires specific tools, like a bench vise with large sockets or a dedicated U-joint press. Without the right tools, it can be a frustrating job.
Are there any recalls for the U-joints on these cars?
No, searches of the National Highway Traffic Safety Administration (NHTSA) database did not find any recalls or technical service bulletins (TSBs) related to the universal joints for the 1973-1981 Buick Regal. Any recalls found for the Buick Regal are for much newer model years and unrelated systems.
Technical Specifications
Most 1973-1981 Buick Regals use two U-joints on a single driveshaft. Common styles use inside or outside lock rings (snap rings) to hold the bearing caps in place. It is crucial to confirm the correct size and lock ring style for your specific year and model before ordering.
