1985-1991 Eagle Vista Rack and Pinion: Solving Steering Issues and the AWD-Only Rule
This guide covers the symptoms, diagnosis, and replacement of the power steering rack for the 1985-1991 Eagle Vista, with a critical focus on its All-Wheel Drive (AWD) specific fitment.
- This rack and pinion (MB553571) fits 1985-1991 Eagle Vista AWD models ONLY and will not work on FWD vehicles.
- The most definitive sign of failure is leaking power steering fluid from the rubber boots at the ends of the rack.
- When replacing the rack, you must also flush the power steering system and get a professional wheel alignment to prevent damage and ensure safety.
- A good, inspected used OEM rack is often the most practical and reliable option for a vehicle of this age, as new parts are unavailable.
Critical Compatibility: AWD Models Only
Warning: The power steering rack and pinion for the 1985-1991 Eagle Vista, OEM part number MB553571, is designed exclusively for All-Wheel Drive (AWD) models. It will not fit Front-Wheel Drive (FWD) vehicles. This part is also shared with the AWD versions of the Mitsubishi Colt Vista and Plymouth Colt Vista. Always verify your vehicle is an AWD model and that the part number matches before ordering.
Symptoms of a Failing Rack and Pinion
A worn or failing steering rack will give several warning signs. Ignoring them can lead to a complete loss of power assist or unpredictable steering, which is a major safety risk.
1. Steering Noises
Unusual sounds when turning the wheel are a primary indicator of a problem. You might hear:
- Clunking or Knocking: A clunking sound when you start a turn or go over bumps often points to worn internal gears or loose mounting bushings that allow the rack to shift.
- Grinding: A metallic grinding noise suggests metal-on-metal contact inside the rack, likely due to a lack of lubrication from a fluid leak.
- Whining or Groaning: While often associated with a failing power steering pump, a whining noise that gets louder when you turn can also indicate the rack is struggling due to low or contaminated fluid.
2. Changes in Steering Feel
- Stiff or Heavy Steering: If turning the wheel suddenly requires much more effort, especially at low speeds, the rack may not be receiving enough hydraulic pressure or could be binding internally.
- Loose Steering or "Play": This feels like a dead spot when you turn the wheel; the car doesn't respond immediately. This looseness is caused by worn internal components.
- Steering Wheel Doesn't Return to Center: After a turn, the steering wheel should naturally start to move back to the straight-ahead position. If it sticks or you have to manually turn it back, the rack may be binding.
3. Fluid Leaks and Condition
A visual inspection can reveal a lot about the health of your steering rack.
- Visible Leaks: Reddish or brown fluid puddles under the front of your car are a classic sign of a power steering leak. The most common failure point is the seals at either end of the rack. Check the rubber accordion-like boots on the ends of the rack; if they are wet, swollen, or dripping fluid, the internal seals have failed.
- Fluid Color and Smell: Healthy power steering fluid is typically bright red or pink. If the fluid in your reservoir is dark brown or black, it is contaminated with debris from worn seals or has been damaged by heat. A burnt smell also indicates overheated, ineffective fluid.
- Metal Particles in Fluid: If you see shiny metallic specks in the fluid, it's a sign of severe internal wear in the rack or the power steering pump.
Buying a Used 1985-1991 Eagle Vista Rack and Pinion
For a vehicle of this age, a new OEM rack is likely discontinued. Your primary options will be a used OEM part or a remanufactured unit. A good-quality used OEM rack is often a reliable and cost-effective choice.
What to Inspect on a Used Rack
- Confirm the Part Number: Ensure the part is stamped with or cross-references to MB553571 and was removed from an AWD model.
- Check the Boots: Squeeze the rubber boots at both ends of the rack. They should be dry, clean, and flexible. If they are oily, wet, or cracked, the internal seals have failed, and the rack is no good.
- Inspect the Inner Tie Rods: The rack assembly includes the inner tie rods. Grab each one and try to move it in and out and up and down. There should be no clunking or excessive play. They should feel stiff to move.
- Look for Corrosion: Check the main housing and the fluid lines for heavy rust or damage. Improper storage can cause corrosion that leads to future leaks.
- Ask About Mileage: While age is the biggest factor, a rack from a lower-mileage vehicle is always preferable. There is no specific mileage where these racks fail, but failure is a result of cumulative wear and seal degradation over decades.
Used OEM vs. Remanufactured
A remanufactured rack has been disassembled, cleaned, and rebuilt with new seals and wear items. This can be a great option, but quality varies. A low-quality remanufactured unit may fail sooner than a high-quality, inspected used OEM part. If choosing remanufactured, select a supplier with a good reputation and a solid warranty. For a vintage vehicle like the Eagle Vista, a well-inspected used original part is often the most practical and reliable solution.
Known Issues, TSBs, and Recalls
As of mid-2026, there are no specific recalls or Technical Service Bulletins (TSBs) issued by the NHTSA for the power steering rack on the 1985-1991 Eagle Vista or its direct Mitsubishi counterparts in the North American market. Failures are generally attributed to the age and wear of seals and internal components.
Replacement Overview and Related Parts
Replacing a steering rack is a job for an experienced DIY mechanic or a professional shop. It requires lifting the vehicle securely and can involve navigating tight spaces. While a detailed, vehicle-specific procedure is beyond this guide's scope, there are several parts that should be addressed at the same time.
Pro Tip: When replacing the rack, it is highly recommended to also replace the outer tie rod ends, flush the entire power steering system, and inspect the power steering hoses for brittleness or swelling. Old, contaminated fluid can quickly damage the seals in your replacement rack.
After replacement, a professional four-wheel alignment is not optional—it is required. Failure to do so will result in poor handling and rapid, uneven tire wear.
Cost to Replace an Eagle Vista Steering Rack
Prices can vary based on your location and the parts chosen. Here are some typical estimates:

|---|---|
| New OEM | Discontinued / Not Available |
| Remanufactured Aftermarket | $190 - $350 |
| Used OEM | $100 - $250 |

| Total Professional Job | $590 - $1250+ |
Frequently Asked Questions
Is the Eagle Vista AWD rack the same as a Mitsubishi Colt Vista AWD rack?
Yes, the 1985-1991 Eagle Vista AWD was a rebadged version of the Mitsubishi Colt Vista AWD (also sold as the Mitsubishi Space Wagon or Chariot in other markets). The power steering rack, OEM part number MB553571, is the same for these AWD models.
Can I just keep adding power steering fluid if it's leaking?
This is a temporary fix at best and is not recommended. A leak will only get worse, and running the system low on fluid can destroy the power steering pump, adding more cost to the repair. A significant leak also poses a safety and environmental hazard.
What happens if the rack and pinion fails completely while driving?
If the hydraulic system fails, you will lose power assist, making the steering wheel extremely difficult to turn, especially at low speeds. While you can still technically steer the car with manual force, the sudden increase in effort required can be startling and dangerous, potentially leading to an accident.
Is a wheel alignment really necessary after replacing the steering rack?
Yes, absolutely. The steering rack is a core component of the suspension and steering geometry. Replacing it will alter the alignment settings (specifically the toe). Skipping the alignment will cause the vehicle to handle poorly, pull to one side, and destroy your front tires in a very short time.
