Dodge Mini Ram AWD Universal Joint Replacement Guide (1987-1988)
If you own an All-Wheel Drive Mini Ram, worn universal joints on your rear driveshaft are a common problem you'll likely face.
- Confirm your van is a 1987-1988 AWD model; these U-joints do not fit FWD versions.
- Symptoms progress from squeaks and clunks to vibrations; do not ignore them to avoid a dangerous driveshaft failure.
- For longevity and strength, Dana Spicer is a top-tier choice; Moog is a good mid-grade option with greasable fittings for maintenance.
- Replacing all U-joints and the center support bearing at the same time is the most effective long-term repair.
Is This The Right Part for Your Van? A Warning for Mini Ram Owners
This part is ONLY for 1987-1988 Dodge Mini Ram models equipped with All-Wheel Drive (AWD).
Front-Wheel Drive (FWD) models from 1984-1988 do not have a rear driveshaft and do not use these universal joints. Ordering these for a FWD van is a common mistake. FWD vans use CV axles for the front wheels, which are a different component. Always verify your van is an AWD model before purchasing.
Symptoms of a Failing Universal Joint
A worn U-joint gives several warning signs. Ignoring them can lead to driveshaft separation, which can cause a loss of power and significant damage to the underside of your van. Listen and feel for these common symptoms:
- Clunking Noise When Shifting: A loud "clunk" or ringing sound when you shift from drive to reverse is a classic sign of a bad U-joint. This noise is caused by excessive play in the worn joint's bearings.
- Vibrations While Driving: You may feel a vibration in the floor or seats that gets worse with speed. This happens because the worn U-joint throws the driveshaft out of balance.
- Squeaking at Low Speeds: A rhythmic squeak or chirp that matches your wheel speed, especially when first starting to move, points to a dry, failing U-joint bearing.
- Transmission Fluid Leak: In severe cases, excessive vibration from a bad U-joint can damage the transmission's rear seal, causing a fluid leak.
Choosing the Right Aftermarket U-Joint
For a vehicle of this age, aftermarket parts are the most common and cost-effective solution. The original OEM parts may be difficult to find or discontinued. Aftermarket brands offer a range of quality and features to fit your budget and needs.
Aftermarket Brand Tiers
| Tier | Brands | Quality & Notes |
|---|---|---|
| Premium | Dana Spicer | Dana is an original equipment (OE) manufacturer, and their Spicer brand is widely considered the benchmark for quality and durability. Many professionals and enthusiasts will only use Spicer, trusting them for longevity and strength, even in demanding conditions. They often feature non-greasable designs, which some find to be stronger and longer-lasting than greasable options. |
| Mid-Grade | Moog | Moog is a well-known aftermarket brand that offers a solid balance of quality and value. A key feature of many Moog U-joints is the greasable fitting (zerk), which allows you to perform regular maintenance to flush out contaminants and extend the part's life. While some users report a decline in quality in recent years, they remain a popular choice. |
| Economy | GMB | GMB is a reputable manufacturer that provides a reliable and budget-friendly option. While they may not have the same high-performance reputation as Spicer, they are a good choice for a daily-driven vehicle needing a dependable, low-cost repair. |
Pro Tip: Greasable vs. Non-Greasable U-Joints
Non-greasable (sealed) U-joints, like many from Spicer, are filled with high-quality grease at the factory and sealed. They are considered stronger because the cross is solid. Greasable U-joints, like many from Moog, have a fitting that lets you add new grease. This can prolong their life if—and only if—you grease them regularly. If you don't plan on doing regular maintenance, a high-quality sealed joint is often the better choice.
Frequently Asked Questions (FAQ)
How many U-joints are on my AWD Mini Ram's driveshaft?
Most AWD Dodge Caravan/Mini Ram models of this era have a two-piece rear driveshaft that uses three universal joints and a center support bearing. It is highly recommended to inspect all three joints and the bearing when you have the driveshaft removed. Replacing them all at once saves on future labor.
Can I replace just the one bad U-joint?
Yes, you can replace only the failing joint. However, if one has failed due to age and mileage, the others are likely not far behind. Given the labor involved in removing the driveshaft, it is cost-effective to replace all the U-joints at the same time.
Is a special tool required for installation?
Proper installation requires pressing the old joints out and the new ones in. While a hydraulic press is the best tool, many DIY mechanics successfully use a sturdy bench vise and a combination of sockets. Some auto parts stores offer tool loaner programs for U-joint/ball joint presses. Using a hammer method is also possible but requires care to avoid damaging the new joint's needle bearings.
Were there any recalls for this issue?
Searches of the NHTSA database did not show any specific universal joint or driveshaft recalls for the 1987-1988 Dodge Mini Ram or Caravan. Recalls for driveshaft issues on other Dodge vehicles have occurred, but they do not apply to this model and year range.
