Subaru Outback Rack and Pinion Guide for 2011-2015 Models
Steering feel loose or hearing noises when you turn? Your rack and pinion might be the problem.
- First, confirm your model year: 2011-2014 Outbacks use a hydraulic rack, while the 2015 model uses an Electric Power Steering (EPS) rack with different symptoms.
- Symptoms for the hydraulic rack include fluid leaks, heavy steering, and whining noises; the electric rack may clunk or rattle.
- An immediate wheel alignment after replacement is not optional; it is required to prevent handling issues and premature tire wear.
- While OEM parts are considered most reliable, the high cost makes a quality new aftermarket part a viable alternative.
Is Your Outback's Steering Rack Failing?
The steering rack is a robust part, but its seals, gears, and bushings can wear out over time. For the 2011-2014 hydraulic systems, the most common failure is fluid leaks. For the 2015 electric system, issues are typically related to the internal electric motor or gears.
Common Symptoms for 2011-2014 (Hydraulic Steering)
- Power Steering Fluid Leaks: Puddles of red or pinkish fluid under the front of your car are a tell-tale sign. Leaks can come from failing seals within the rack.
- Whining or Groaning Noises: A struggling power steering pump, low on fluid due to a leak, will often make noise, especially when turning.
- Stiff or Heavy Steering: If turning the wheel suddenly requires much more effort, it's a classic symptom of losing hydraulic assistance.
- Loose Steering or "Play": A feeling of looseness or a dead spot in the steering wheel can indicate worn internal gears in the rack.
Important Note for 2015 Outback Owners
The 2015 Subaru Outback uses a different Electric Power Steering (EPS) rack. While it can also fail, the symptoms are different. A common issue is a clunking or rattling noise from the front end. Subaru issued a Technical Service Bulletin (TSB 04-17-17R) for this, noting it can sometimes be fixed by replacing a tension spring inside the rack, rather than replacing the entire unit. Complete failure of the EPS system will result in a sudden loss of power assist and an EPS warning light on your dash.
OEM vs. New Aftermarket: An Honest Look
When replacing your steering rack, you have a choice between genuine Subaru (OEM) parts and aftermarket options. Forum discussions among Subaru owners show a strong preference for OEM racks due to their reliability, but the cost is high. Aftermarket racks are more affordable, but quality can be inconsistent. Some owners report remanufactured aftermarket racks leaking or failing shortly after installation. Since replacing the rack is a labor-intensive job, you don't want to do it twice. A high-quality new aftermarket part can be a good compromise between the cost of OEM and the risk of a low-quality remanufactured part.
Choosing an Aftermarket Brand
Based on available information, aftermarket brands can be grouped into different tiers of quality and trust.
- Atlantic Automotive Enterprise (AAE): AAE promotes that its remanufactured units are processed in the USA and tested to meet high standards. Some user reviews are positive, suggesting quality comparable to or better than the original part.
- BBB Industries: Reviews for BBB remanufactured racks are mixed, with some users reporting significant leaks and premature failure, leading them to recommend avoiding the brand.
- Mapco: This brand appears to be a lower-cost option. One forum comment described it as generic but passable for non-critical applications. There is limited information available for this brand in the North American market.
Pro Tip: When replacing the rack, it's highly recommended to also replace the outer tie rod ends. You should also perform a complete power steering fluid flush with genuine Subaru ATF to remove any contaminants that could damage the new rack.

Frequently Asked Questions (FAQ)
Can I replace the steering rack myself?
This is a challenging job for a DIY mechanic. It requires lifting the front of the vehicle, disconnecting fluid lines (which can be messy), and accessing tight spaces. The 2015 electric rack is even more difficult as it may require dropping the subframe. After installation, a professional wheel alignment is mandatory. For most owners, this job is best left to a qualified mechanic.
What fluid should I use for my 2011-2014 Outback?
Subaru specifies using genuine Subaru ATF (Automatic Transmission Fluid), not generic power steering fluid. Using the wrong fluid can damage seals and the power steering pump. The 2015 model's EPS system does not use any fluid.
Do I need a wheel alignment after replacing the rack?
Yes, absolutely. Replacing the steering rack will change your vehicle's front-end alignment. Skipping the alignment will cause poor handling, crooked steering wheel, and rapid, uneven tire wear.
Were there any recalls for the 2011-2015 Outback steering rack?
No. While there have been recalls for other steering components on different Subaru models, the National Highway Traffic Safety Administration (NHTSA) has not issued any recalls specifically for the rack and pinion assembly on the 2011-2015 Outback.
