A guide to diagnosing and choosing the right aftermarket U-joints to fix driveline vibrations and clunks in your classic Volvo.
- Your Volvo 242 has three universal joints in its two-piece driveshaft.
- Symptoms of failure include vibrations on takeoff, clunking when shifting, and squeaking at low speeds.
- Dana Spicer and SKF are considered premium aftermarket brands, while GMB and Moog are decent value options.
- It is highly recommended to replace all three U-joints at once and have the driveshaft balanced.
Is Your Volvo 242's Driveline Making Noise?
A failing universal joint in your 1975-1984 Volvo 242 will almost always give you an audible warning. Because these cars use a two-piece driveshaft, there are typically three U-joints that can wear out. A common symptom is a vibration that starts when you accelerate from a stop and lasts until about 15-20 mph. You might also hear a squeaking noise at very low speeds (1-5 mph) or a distinct "clunk" when you shift gears. Another sign is a rattling sound when you engage the clutch after shifting. These noises are caused by excessive play in the U-joint's needle bearings or by a joint that has seized from rust and lack of grease.
Don't Ignore the Signs
🎬 Watch this guide to help identify a failing U-joint.A worn U-joint that is ignored can eventually fail completely. This can cause the driveshaft to separate from the car, leading to a loss of power and potentially causing significant damage to the underside of your vehicle. If you hear a loud click or clunk when shifting from drive to reverse, it's a strong indicator of excess slop that needs immediate attention.
Choosing the Right Aftermarket U-Joint
When it comes to replacing U-joints on a classic Volvo 242, you have several aftermarket options. Original equipment (OE) parts are likely unavailable or very expensive. Aftermarket brands offer a range of quality and price points. Most brands available today are considered to be of decent quality for a daily-driven vehicle.
Brand Quality Tiers
- Premium Brands (Dana Spicer, SKF): Dana Spicer is widely considered a top-tier brand, and many forum users believe they were the original equipment supplier for Volvo. They are known for durability and quality. SKF is another premium brand known for manufacturing high-quality bearings, though some driveshaft shops have expressed concerns about their U-joint tolerances. However, many users have installed them without issue.
- Mid-Grade/Value Brands (GMB, Moog): GMB is a Japanese manufacturer that has historically produced good quality U-joints. However, some users in recent years have noted a decline in quality, potentially due to manufacturing moving from Japan to China. Moog is a well-known aftermarket brand, but their quality can be inconsistent, with some users reporting good experiences while others call them "cheap China crap."
- Specialty/Heavy-Duty (Yukon Gear): Yukon Gear & Axle specializes in high-performance and heavy-duty drivetrain components. Their U-joints are built for superior strength and longevity, often for off-road or racing applications. For a standard Volvo 242, Yukon might be overkill, but they represent a very high-quality option.
- Economy Brands (URO Parts): URO Parts are generally considered a budget-friendly option. While they meet basic specifications and often come with a good warranty, many enthusiasts on forums advise against using them for critical components, citing lower quality control and materials.
Greasable vs. Sealed U-Joints
Many aftermarket U-joints are "greasable," meaning they have a zerk fitting that allows you to add fresh grease periodically. This can extend their life if maintained properly. Non-greasable (sealed) joints are often considered stronger because the cross is solid, and they typically have better seals from the factory. For a daily driver, either type is acceptable, but greasable joints require you to remember to service them.
Cost of Replacement
The cost to replace your Volvo 242's U-joints will depend on the parts you choose and whether you do the work yourself. The job can be done by a confident DIYer, but it requires specific tools.
| Item | Estimated Cost |
|---|---|
| New Aftermarket U-Joints (Per Joint) | $15.37 - $107.89 |
| Shop Labor (Per Joint, estimate) | $100 - $200 |
| Driveshaft Balancing (Recommended) | $50 - $100 |
Frequently Asked Questions
How many U-joints does my 1975-1984 Volvo 242 have?
Most Volvo 240-series cars have a two-piece driveshaft with three universal joints. One is located behind the transmission, one is near the center support bearing, 🎬 See how to replace the center support bearing and bushing. and the third is in front of the rear differential.
Should I replace all three U-joints at the same time?
It is highly recommended. If one joint has failed due to age and wear, the others are likely not far behind. Replacing all of them at once saves on labor costs in the long run and ensures a reliable, vibration-free driveline.
Do I need to balance the driveshaft after replacing the U-joints?
Yes, it is a good practice to have the driveshaft assembly balanced after installing new U-joints. While marking the driveshaft orientation before disassembly helps, slight variations in the new parts can introduce vibrations. A driveshaft shop can balance the assembly to ensure smooth operation at all speeds.
Can I replace a U-joint myself?
Yes, this is a DIY-feasible job if you have the right tools. You will need to remove the driveshaft from the car. Removing the old U-joints and pressing in the new ones requires a sturdy bench vise, a hammer, and a set of sockets, or a specialized U-joint press tool. It is crucial to avoid damaging the driveshaft yokes or dislodging the needle bearings 🎬 Watch this step-by-step walkthrough for replacing your Volvo 240 U-joints. inside the new U-joint caps during installation.

Technical Specifications
Volvo 240-series cars from this era used different driveshaft diameters and U-joint sizes. It is critical to measure your existing U-joints (cap diameter and overall length) before ordering replacements. Some 1982 models, for example, may have a smaller 1.75" driveshaft with smaller U-joints. Always verify fitment for your specific vehicle.
