Chevrolet V20 Universal Joint: A Guide for the 1987 Model Year
If your 1987 V20 is making clunking or vibrating noises, your U-joints might be the culprit.
- Listen for clunking when shifting gears or vibrations at highway speeds, as these are the most common symptoms of a bad U-joint.
- For a heavy-duty 4x4 truck like the V20, premium greasable U-joints from brands like Dana/Spicer or SKF are highly recommended by other owners.
- Your 1987 V20 has multiple U-joints of potentially different sizes; always measure your old parts before ordering replacements to ensure you get the correct fit.
- Replacing a failing U-joint promptly is a critical safety repair that prevents the driveshaft from detaching and causing catastrophic damage.
Is Your V20 Making Strange Noises? It Could Be the U-Joints
Universal joints are common wear items on classic trucks like the 1987 Chevrolet V20, especially if the truck is used for hauling, towing, or off-roading. When they start to fail, they give several distinct warning signs. 🎬 Watch this video to identify common signs of U-joint failure. Ignoring these symptoms can lead to a complete failure where the driveshaft can detach from the vehicle, causing a loss of power and potentially severe damage to other components.
Choosing the Right Aftermarket U-Joint
When replacing U-joints on your V20, you have a choice between original equipment (OEM) quality parts and various aftermarket brands. For a vehicle of this vintage, aftermarket support is strong and many options are considered equal to or better than the original parts. The main decision often comes down to choosing between a greasable or a non-greasable (sealed) joint.
Greasable U-joints have zerk fittings that allow you to add fresh grease periodically. This maintenance can extend the life of the joint, especially for trucks that see heavy use. Many experienced owners and shops prefer them for their longevity if properly maintained. Non-greasable (sealed) U-joints are maintenance-free, just like the original factory parts. They are strong and reliable for tens of thousands of miles but must be replaced when they wear out. For a workhorse like the V20, greasable joints from a quality brand are often the recommended choice.
Aftermarket Brand Tiers for Your V20
Not all aftermarket brands are created equal. Based on owner feedback in truck forums, brands can be grouped into tiers.
- Premium/Heavy-Duty (Recommended): Brands like Dana/Spicer and SKF are consistently recommended by truck owners for their durability and quality. Spicer is a well-known original equipment supplier for many driveline components, and their parts are trusted for heavy use.
- Quality Mid-Range: Moog is another popular brand, often praised for its "problem-solver" designs, though some users have noted a decline in quality in recent years compared to older products. ACDelco, GM's official parts brand, offers a reliable, OEM-equivalent option.
- Standard/Economy: Brands like GMB offer a good balance of affordability and quality for standard use. While generally reliable, they may not have the same long-term durability under heavy loads as premium brands.

Frequently Asked Questions (FAQ)
How many U-joints does a 1987 Chevy V20 have?
A 4x4 truck like the V20 typically has multiple U-joints. There are usually two on the rear driveshaft and two or three on the front driveshaft (if it has a Cardan joint). Additionally, there are U-joints in the front axle shafts that allow the front wheels to steer while receiving power. It's a good idea to inspect all of them if you suspect one is failing.
Can I replace just one bad U-joint?
Yes, you can replace only the failing U-joint. However, if one has failed due to age or mileage, the others are likely near the end of their service life as well. It is often recommended to replace all the U-joints on a driveshaft at the same time for peace of mind and to avoid doing the same job again soon.
Is replacing a U-joint a difficult job for a DIYer?
Replacing a U-joint is a moderately difficult job that requires specific tools, such as a large vise, a ball joint press, or a dedicated U-joint press tool. While it can be done with hammers, there is a high risk of damaging the driveshaft yoke or the new U-joint bearings. If you don't have the right press tools, it may be best to take the driveshaft to a shop for the U-joint installation.
Are there any recalls for the 1987 Chevrolet V20 U-joints?
No, there are no specific recalls or technical service bulletins (TSBs) from Chevrolet or the NHTSA related to universal joint failure on the 1987 V20. U-joint failure is typically considered normal wear and tear for a vehicle of this age.
