Chevrolet V10 Universal Joint: A Complete Replacement Guide for 1987 Models
Don't let a bad U-joint sideline your classic 1987 V10; here's how to choose the right replacement part.
- Symptoms of failure include clunking when shifting, vibrations at speed, and squeaking noises.
- Dana/Spicer is the most recommended brand for durability and strength, often considered OEM-quality.
- Non-greasable (sealed) U-joints are typically stronger than greasable versions and are preferred by many experts.
- Due to multiple configurations, always measure your old U-joints before ordering replacements to ensure correct fitment.
Is Your 1987 V10's U-Joint Failing?
U-joints are tough, but they don't last forever, especially on a hard-working truck. The needle bearings inside the caps can wear out from age, lack of lubrication, or harsh use. When they fail, they give clear warning signs. Ignoring them can lead to a disconnected driveshaft, leaving you stranded and facing a much more expensive repair.
Key Failure Symptoms
- Squeaking or Clicking: A rhythmic squeak or click that changes with speed, often most noticeable when you first start moving, is a classic sign of a dry U-joint.
- Clunking or Ringing Sound: A distinct "clunk" or "ping" when you shift from park into drive or reverse points to excessive play in a worn U-joint.
- Vibration: A vibration you can feel through the floor of the truck, especially at highway speeds, often means a U-joint is worn and causing the driveshaft to become unbalanced.
- Fluid Leaks: In advanced cases, a wobbly driveshaft from a bad U-joint can damage the output seal on your transmission or transfer case, causing a fluid leak.
Warning: Do Not Ignore a Failing U-Joint
A complete U-joint failure will cause the driveshaft to disconnect from the truck. If this happens at speed, the flailing driveshaft can cause catastrophic damage to the transmission, exhaust, fuel lines, and underbody, turning a simple repair into a major project.
Choosing the Right Aftermarket U-Joint
For a 1987 V10, you won't be finding new OEM parts on a dealership shelf. The aftermarket is your only option, but the quality varies significantly between brands. The two main types you'll encounter are greasable and non-greasable.
Greasable vs. Non-Greasable (Sealed)
- Non-Greasable (Sealed): These are designed like the original factory joints. High-quality sealed joints from brands like Dana/Spicer are often considered the strongest and most durable option because their internal cross is solid steel. They are an excellent "install-and-forget" choice for most users.
- Greasable: These joints have a zerk fitting that allows you to add fresh grease. This can extend their life, especially if your truck sees a lot of mud or water, as new grease pushes out contaminants. However, the cross is hollow to allow grease to pass through, which technically makes them weaker than a solid joint. They only provide a benefit if you are diligent about regular maintenance.
Aftermarket Brand Tiers for Your V10
Based on owner feedback and mechanic consensus, aftermarket U-joints for your truck fall into a few tiers.
- Top Tier (OEM Quality or Better): Dana Spicer Chassis is the most recommended brand for these trucks. They were an original equipment supplier to GM and are known for excellent strength and durability. Many consider their solid, non-greasable joints to be the strongest option available.
- Premium Aftermarket: Moog and SKF are also strong contenders. Moog's "Super Strength" line is popular, and some of their designs feature a grease zerk in the bearing cap, which is easier to access for maintenance. However, some users have noted a decline in Moog's quality in recent years, so check the country of origin. SKF is a well-respected bearing manufacturer with a reputation for quality parts.
- Standard/Economy: Brands like GMB and store brands (e.g., Duralast) are typically more budget-friendly. They can be a suitable choice for a daily driver under normal conditions, but may not have the ultimate strength or longevity of the premium brands, especially for a 4x4 that is used for towing or off-roading.
- GM's Brand: ACDelco is GM's official parts brand. Their professional-grade U-joints are a reliable choice, though they are often manufactured by companies like Moog/Federal-Mogul.
Pro Tip: Measure Before You Buy
Over the years, your truck may have had its driveshaft or axles swapped. The 1973-1987 GM trucks used several different U-joint sizes. The safest approach is to remove your old U-joint and measure its cap diameter and width before ordering a replacement to guarantee a perfect fit.
Estimated Costs for U-Joint Replacement
| Part Type | Estimated Part Cost |
|---|---|
| New Aftermarket (Standard) | $18 - $40 |
| New Aftermarket (Premium) | $40 - $100+ |
| Shop Labor | $150 - $400 per driveshaft |
Note: Costs are estimates. Shop labor can vary significantly by location. Replacing U-joints in the front axle shafts is a more labor-intensive job and will cost more. 🎬 Watch: How to replace U-joints on a Dana 44 front axle.
Frequently Asked Questions
How many U-joints does my 1987 V10 have?
Your 4x4 V10 has multiple U-joints. Typically, there are two on the rear driveshaft, two or three on the front driveshaft (depending on if it has a CV joint), and one in each front axle shaft near the wheel for steering. A full replacement can involve seven or more U-joints.
Should I replace all the U-joints at once?
If one U-joint has failed due to age and mileage, the others are likely near the end of their service life as well. If you are already removing a driveshaft to replace one joint, it is cost-effective and good preventative maintenance 🎬 Watch: A step-by-step guide to changing square body U-joints. to replace the other joint(s) on that same shaft.
Do I need to balance my driveshaft after replacing the U-joints?
If you carefully mark the orientation of the driveshaft to the yokes before removal and reinstall it in the exact same position, you usually do not need to re-balance it. However, if you experience a new vibration after the repair, the driveshaft may need to be professionally balanced.
What makes original U-joint removal difficult on these trucks?
Many original GM U-joints from this era were installed using an injected plastic compound to hold the caps in place instead of snap rings. To remove them, this plastic must be melted out with a torch until it liquefies and squirts out of the relief holes. Once the plastic is gone, the joint can be pressed out.

U-joint sizes vary. Common styles for this truck use outside snap rings or are the original injected-plastic style. It is critical to measure bearing cap diameter and the overall width to find the correct replacement part.
