Chrysler Cordoba Universal Joint Guide: 1975-1983
Eliminate driveline clunks and vibrations by choosing the correct replacement U-joint for your Cordoba.
- You must measure your existing U-joints before ordering; your Cordoba could have the 'small' 7260 or 'large' 7290 series.
- Always replace both U-joints on the driveshaft at the same time to save on future labor.
- Dana Spicer is the most recommended brand for durability and OEM-level quality.
- A loud clunk when shifting into gear and vibrations at speed are the most common signs of a bad U-joint.
Symptoms of a Failing Universal Joint
When a U-joint in your Cordoba starts to fail, it will give you clear warning signs. The bearings inside the U-joint caps wear out, often from a lack of lubrication, creating excessive play in the driveline. Ignoring these symptoms can be dangerous, as a complete failure can cause the driveshaft to disconnect from the vehicle.
- Clunking Noise: The most common symptom is a loud 'clunk' or 'bang' when you shift into Drive or Reverse. You might also hear this noise when you accelerate or decelerate quickly. This is caused by the extra slack in the worn-out joint.
- Vibration: A vibration that you can feel through the floor of the car, especially at highway speeds, is another key sign. This vibration happens because the worn U-joint throws the driveshaft out of balance. It may be confused with an unbalanced tire, but a U-joint vibration is felt more in the center of the car.
- Squeaking or Chirping: A rhythmic squeaking noise that increases with your speed often points to a U-joint that has lost its grease and is running dry. The sound comes from metal-on-metal contact inside the joint's bearing caps.
Known Issues for This Vehicle
No recalls or Technical Service Bulletins (TSBs) related to universal joints are on file with the NHTSA for the 1975-1983 Chrysler Cordoba. Any failures are typically due to normal wear and tear over the vehicle's long life. The most significant issue for owners is ensuring the correct size is purchased, as Chrysler used two different U-joint sizes during this period.
Choosing the Right Aftermarket U-Joint
For a classic vehicle like the Cordoba, aftermarket parts are the primary option. Original OEM parts from Mopar are likely discontinued. The quality of aftermarket U-joints varies, but several reputable brands are available.
Greasable vs. Non-Greasable Joints
You will see options for both greasable and non-greasable (sealed) U-joints. Non-greasable joints are what most cars came with from the factory. They are considered stronger because the internal cross is solid steel. Greasable joints have a fitting (zerk) that allows you to add fresh grease, which can extend their life if done regularly. However, the channel for the grease makes the cross technically weaker, though this is not a concern for a stock Cordoba. For a daily driver, a quality non-greasable joint is often preferred for its strength and maintenance-free design.
Brand Quality Tiers
- Premium (OEM Quality): Dana Spicer is widely considered the gold standard and was an original equipment manufacturer for many brands, including Chrysler. If you want the best fit and longest life, Spicer is the top choice.
- Quality Aftermarket: Moog and SKF are well-respected aftermarket brands that offer high-quality replacement parts. Moog is known for its premium problem-solver parts, though some forum users have noted inconsistent quality in recent years. SKF is a reliable alternative.
- Standard Replacement: GMB is a common brand that offers a reliable, budget-friendly option for a standard replacement.
Critical: Check Your Cordoba's U-Joint Size!
Chrysler used two main U-joint sizes in this era: the 7260 series (small) and the 7290 series (large). The 7260 was typically used on cars with the A-904 transmission, common with the 318 and 360 V8 engines. The heavy-duty 7290 was often paired with the A-727 transmission. It is essential to measure your existing U-joint or yoke before ordering. The 7260 fits a yoke with an inside span of 2.125 inches, while the 7290 fits a yoke with an inside span of 2.625 inches. Some cars may even have a combination of sizes.
Estimated Cost of Replacement
Replacing U-joints is a relatively affordable repair, especially if you can do the labor yourself. The parts themselves are not expensive.
| Item | Estimated Cost |
|---|---|
| New Aftermarket U-Joint (per piece) | $17 - $57 |
| Shop Labor | $150 - $300 |

Frequently Asked Questions (FAQ)
How many U-joints does my Cordoba have?
Your Chrysler Cordoba has two universal joints on the rear driveshaft. One is located at the transmission end (front) and the other is at the rear differential end (rear).
Should I replace both U-joints at the same time?
Yes. It is highly recommended to replace both U-joints at the same time. The driveshaft must be removed to replace either one, so you save on future labor. If one has failed due to age and mileage, the other is likely not far behind.
What is the difference between a 7260 and 7290 U-joint?
These are Chrysler-specific size references. The 7260 is the 'small' joint and fits a yoke with an inner width of 2.125 inches. The 7290 is the 'large' joint and fits a yoke with an inner width of 2.625 inches. You must verify which size your car has before buying parts, as it can vary based on the original engine and transmission combination.
Can I replace a U-joint myself?
This is a feasible DIY job for someone with mechanical experience, but it requires specific tools. After removing the driveshaft, you need a heavy-duty bench vise and large sockets or a hydraulic press to push the old joints out and press the new ones in. If the bearing caps are not pressed in perfectly straight, the needle bearings can be damaged.
Technical Specifications
Common sizes are the Chrysler 7260 series (2.125" inside yoke span) and 7290 series (2.625" inside yoke span). Both use internal clips to retain the bearing caps.
