1958 Edsel Pacer Universal Joint Replacement and Diagnosis
Keep your classic Edsel running smoothly by learning to spot and replace a worn universal joint.
- A clunking noise when shifting or a vibration at speed are the most common signs of a failing U-joint.
- Do not drive with a bad U-joint; a complete failure can cause the driveshaft to detach, leading to a loss of control and major damage.
- For a 1958 Edsel, aftermarket brands like SKF and GMB offer quality replacements that often exceed original 1950s standards.
- Always replace both U-joints at the same time to save on future labor and ensure a balanced, vibration-free driveline.
Is Your Edsel Pacer Trying to Tell You Something?
A failing universal joint doesn't happen silently. Your classic Edsel will give you clear warning signs that it's time for a replacement. One owner of a 1958 Edsel noted that U-joint failure was a problem, possibly due to the engine's high torque. Ignoring these symptoms can lead to a catastrophic failure where the driveshaft detaches from the car, potentially digging into the pavement and causing a loss of control or severe damage to the undercarriage.
Key Failure Symptoms
- Clunking or Banging Noise: The most common sign is a distinct "clunk" when you shift from Park into Drive or Reverse. This is the sound of slack in the worn-out joint being taken up.
- Vibration at Speed: A vibration that you can feel through the floor of the car and gets worse as you accelerate. This is often mistaken for an unbalanced tire, but if a tire balance doesn't solve it, the U-joints are a primary suspect.
- Squeaking or Chirping: A rhythmic squeak that matches the speed of the wheels, most noticeable at low speeds. This usually means the needle bearings inside the U-joint have lost their grease and are failing.
- Transmission Fluid Leak: In advanced stages of failure, the excessive vibration can damage the output seal on your transmission, causing a fluid leak.
Choosing the Right Aftermarket U-Joint for Your Pacer
For a classic car like the 1958 Edsel Pacer, finding new original equipment (OEM) parts is nearly impossible. The parts available today are new aftermarket U-joints, which are often made with modern materials and to higher standards than the originals. The main choice is between brands like GMB and SKF.
Brand Quality Assessment:
- SKF: Generally considered a global leader in bearings, SKF manufactures U-joints designed to meet or exceed original specifications. They offer a wide range of applications, including for classic cars. Some users have had positive experiences, noting good build quality, while others have reported occasional issues with fitment or prefer other brands like Spicer for classic applications.
- GMB: GMB is another well-known manufacturer that produces quality U-joints, often using strong Chrome-Molybdenum steel. They are a popular choice for both DIY and professional mechanics. Forum discussions show mixed reviews over the years; some users find them to be excellent quality, while older forum posts from nearly two decades ago mention concerns about roughness in new parts.
Pro Tip: For a 1958 Edsel Pacer, both SKF and GMB are reputable choices that will likely provide reliable service. Since the Pacer shares its chassis and many drivetrain components with the 1958 Ford, parts are generally interchangeable and readily available. It is highly recommended to replace both U-joints at the same time. Since the driveshaft must be removed to replace one, replacing the second adds very little extra labor and ensures the entire assembly is fresh, preventing future vibrations or failures.

Frequently Asked Questions (FAQ)
How many U-joints does my 1958 Edsel Pacer have?
Your Pacer has a single driveshaft with two universal joints—one connecting to the transmission and one connecting to the rear axle. It is best practice to replace them as a pair.
Can I replace the U-joints myself?
Yes, this is a manageable job for a DIY mechanic with the right tools. The main challenge is removing the old U-joint from the driveshaft yoke and pressing the new one in. This typically requires a large bench vise, a hydraulic press, or the careful use of sockets and a hammer. Rust can make removal difficult.
Should I choose a greasable or non-greasable U-joint?
Greasable U-joints have a fitting that allows you to add new grease periodically, which can extend their life if maintained. Non-greasable (or sealed) joints are lubricated for life and often have better seals to keep contaminants out. For a classic car that may not be driven daily, either type is a good option, but sealed joints offer a maintenance-free experience.
Are there any recalls for the 1958 Edsel Pacer's U-joints?
No. A search of the National Highway Traffic Safety Administration (NHTSA) database shows no recalls or technical service bulletins (TSBs) for the 1958 Edsel Pacer's universal joints. The NHTSA database does not contain recall information for vehicles older than 15 years unless a manufacturer offers special coverage.
Technical Specifications
The 1958 Edsel Pacer was built on the Ford platform with a 118-inch wheelbase. It uses two universal joints on the main driveshaft. Drivetrain components are largely shared with 1958 Ford models, making parts cross-compatibility high.
