Chevrolet Silverado (1995-1999) Universal Joint Replacement Guide
Don't let a clunking or vibrating driveshaft leave your Silverado stranded; here's what you need to know about replacing your U-joints.
- Symptoms include clunking when shifting, squeaking at low speeds, and vibrations that get worse as you drive faster.
- Complete failure is dangerous; address symptoms immediately to avoid the driveshaft detaching from the truck.
- Dana Spicer is the top-tier brand for durability; GMB is a solid, affordable alternative.
- You MUST measure your old U-joint's bearing cap diameter before ordering, as multiple sizes were used on these trucks.
Is Your Silverado Clunking, Squeaking, or Vibrating?
A failing universal joint is a common issue on hardworking GMT400-platform trucks like the '95-'99 Silverado. These parts are under constant stress, and when they wear out, they give clear warning signs. Ignoring them can lead to the driveshaft separating from the truck, which can cause a loss of control and expensive damage to your transmission, exhaust, and other underbody components. It is a repair that should not be put off.
Symptoms of a Bad U-Joint
🎬 Watch: 7 common signs of a failing universal joint- Clunking or Ringing Noise: A distinct "clunk" when you shift from drive to reverse is a classic sign of a worn U-joint with too much play.
- Squeaking or Chirping: A rhythmic squeak, like a bird chirping, that matches your wheel speed and is most noticeable at low speeds (5-10 mph) is a tell-tale sign. This often means the internal needle bearings have lost their grease.
- Vibration: A vibration that you can feel through the floor or seats that gets worse as you accelerate is a common symptom. This is often mistaken for a tire balance issue, but if it changes with speed, a U-joint is a likely culprit.
- Transmission Fluid Leak: In severe cases, the vibration from a completely failed U-joint can damage the rear seal on the transmission or transfer case, causing a fluid leak.
Warning: Driveshaft Separation
If a U-joint fails completely, the driveshaft can detach from the vehicle. This will result in an immediate loss of power and can cause the driveshaft to dig into the pavement, potentially causing you to lose control of the truck or causing significant secondary damage. If you experience severe clunking or vibration, stop driving the vehicle.
Choosing the Right Aftermarket U-Joint
For the 1995-1999 Silverado, several aftermarket options are available that meet or exceed original factory quality. The main choice comes down to brand reputation and whether you prefer a greasable or non-greasable design.
Pro Tip: Measure Before You Buy!
The single most common ordering mistake for this generation of Silverado is getting the wrong size U-joint. Chevrolet used several different sizes during these years, with common bearing cap diameters of 1 1/8" and 1 3/16". It is essential to remove and measure your old U-joint's bearing cap diameter before ordering a replacement to guarantee a correct fit.
Brand Tiers
- Tier 1 (OEM Quality): Dana Spicer
Dana/Spicer is widely considered the premier choice for U-joints and was an original equipment supplier for many trucks. Forum users and mechanics consistently recommend their products for durability and quality. Their non-greasable "Spicer Life Series" joints are sealed from the factory and are a fit-and-forget solution, much like the original parts. For a truck that works hard, tows, or goes off-road, Spicer is the recommended brand. - Tier 2 (Quality Aftermarket): GMB
GMB is a well-known aftermarket manufacturer that produces quality parts built to OE specifications. They offer a reliable replacement part for a daily driven or standard-use truck. While they may not have the same heavy-duty reputation as Dana Spicer, GMB U-joints are a dependable and cost-effective option.
Greasable vs. Non-Greasable U-Joints
You will find both greasable (with a zerk fitting) and non-greasable (sealed) U-joints. Original factory joints were non-greasable. Non-greasable joints, like the Spicer Life series, are generally considered stronger because the cross is solid, not drilled out for a grease channel. They are also maintenance-free. Greasable joints can have a long life if, and only if, they are greased at every oil change. For most owners, a high-quality non-greasable joint is the more durable and reliable option.

Frequently Asked Questions (FAQ)
How many U-joints does my 1995-1999 Silverado have?
It depends on your configuration. A 2WD regular cab truck typically has two U-joints on the rear driveshaft. A 4WD truck will have at least four: two on the rear shaft and two on the front shaft. Some extended cab or long bed models may have a two-piece rear driveshaft with a third U-joint and a center support bearing, bringing the total to five.
🎬 See a full DIY driveshaft and center bearing rebuildIs replacing a U-joint a DIY job?
It can be, but it is considered a moderately difficult job. You will need to safely remove the driveshaft. The hardest part is pressing the old joint out and the new one in, which typically requires a bench vise, a ball joint press, or a hammer and sockets. Crucially, many original factory joints were held in with injected plastic that must be melted out with a torch before the joint can be removed. If you are not comfortable with this, professional installation is recommended.
🎬 Watch this step-by-step guide to removing GMT400 U-jointsWere there any recalls for the Silverado U-joint?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database show no safety recalls or Technical Service Bulletins (TSBs) specifically for universal joints on the 1995-1999 Chevrolet Silverado.
I replaced my U-joints but still hear a clunk. What's wrong?
If you've installed new, quality U-joints and still have a clunking noise when shifting into gear, the problem may be excessive play in the slip yoke. The slip yoke is the internal-splined part of the driveshaft that slides into the transmission or transfer case. Wear in these splines is a known issue on this generation of truck and can cause a similar clunking sound.
