Is This For My Vehicle?
This guide applies only to All-Wheel Drive (AWD) models of the 1992-1995 Eagle Summit. These U-joints are located on the rear driveshaft, which sends power to the rear wheels. If you have a Front-Wheel Drive (FWD) model, you do not have these components.
Symptoms of a Failing Universal Joint
A worn U-joint will give you several warning signs. The most common is a loud "clunk" or "ping" sound when you shift into Drive or Reverse. You may also hear a cyclical squeaking or chirping noise that gets faster as you accelerate. Another major symptom is a vibration felt throughout the vehicle, which becomes more noticeable at highway speeds. This vibration is often confused with an unbalanced tire, but it's caused by the failing U-joint allowing the driveshaft to wobble. You might also see rust-colored dust around the U-joint, which is a sign the internal needle bearings are failing.
Do Not Ignore a Failing U-Joint
A U-joint that fails completely can cause the driveshaft to detach from the vehicle. This can cause a loss of control, significant damage to the undercarriage, and is a serious safety hazard. If you suspect your U-joint is bad, it should be inspected and replaced immediately.
Choosing the Right Aftermarket U-Joint
For a vehicle like the 1992-1995 Eagle Summit, original equipment (OEM) parts are generally no longer available. The aftermarket offers several quality options that meet or exceed the original specifications. Your choice depends on your budget and performance expectations.
Brand Quality Tiers
- Best (Premium Replacement): Brands like Dana Spicer are widely considered the highest quality in the industry. They are often the original supplier for many vehicle manufacturers and are known for exceptional durability and performance, making them a top choice for a long-lasting repair.
- Good (Standard Replacement): Brands like GMB are well-regarded aftermarket manufacturers that produce reliable, standard-replacement parts. These offer a good balance of quality and affordability for a daily driver.
Greasable vs. Sealed U-Joints
Some aftermarket U-joints come with a zerk fitting that allows you to add grease periodically, which can extend their life. Others are sealed and require no maintenance, just like the original part. If you choose a greasable joint, remember to lubricate it according to the manufacturer's instructions, typically during oil changes.
Estimated Replacement Costs
The cost to replace a U-joint can vary based on your location and the shop's labor rate. While the part itself is inexpensive, the labor can be significant.
| Part/Service | Estimated Cost |
|---|---|
| Aftermarket Universal Joint | $16 - $59 |
| Shop Labor | $180 - $400 |
| Total Estimated Cost | $196 - $459 |

Frequently Asked Questions (FAQ)
Can I replace a U-joint myself?
This is a difficult job for a beginner. It requires removing the driveshaft and using a hydraulic press or a large bench vise with specific sockets to press the old joint out and the new one in without damaging the driveshaft yoke. Many experienced DIY mechanics will remove the driveshaft themselves and take it to a machine shop to have the U-joint pressed in professionally.
How many U-joints does my AWD Eagle Summit have?
A typical rear driveshaft has two universal joints: one at the transmission/transfer case end and one at the rear differential end. It is recommended to inspect both and replace them in pairs if they are the same age.
Will a bad U-joint cause a Check Engine Light?
No, a failing universal joint is a mechanical issue and will not trigger a Check Engine Light or any diagnostic trouble codes.
Are there any recalls for the Eagle Summit universal joint?
No, there are no recalls or Technical Service Bulletins (TSBs) on record with the NHTSA for universal joint issues on the 1992-1995 Eagle Summit.
