The 2015 Ram 1500 with the 5.7-liter HEMI V8 and 4×4 drivetrain remains one of the most popular full-size pickup trucks on the used market. Buyers appreciate its strong towing capability, comfortable driving feel, and modern features. However, when owners begin repairing or modifying these trucks, one question appears frequently:
Does the 2015 Ram 5.7 4×4 Have Electric Power Steering?
No. The 2015 Ram 1500 with the 5.7 HEMI uses a hydraulic power steering system, not an electric one.
All 2015 Ram 1500 models, including 2WD and 4×4 versions, still relied on a traditional hydraulic pump driven by the engine. This also means it uses:
- Power steering fluid
- Hydraulic hoses and lines
- A belt-driven pump
- A hydraulic steering rack or gear
Electric power steering (EPS) did not appear on Ram 1500 trucks until later model years, with more widespread adoption around 2019 and beyond.
Why the 2015 Ram Still Used Hydraulic Steering
Many automakers switched to electric power steering earlier, but Ram continued with hydraulic steering on the 1500 for several reasons:
1. Towing and Load Stability
Hydraulic steering systems deliver strong assist and durability under heavy load. Ram trucks in this era were designed for:
- Heavy trailers
- High tongue weight
- Rough off-road terrain
A hydraulic system provided predictable steering feel under maximum strain.
2. Driver Feedback
Truck owners often prefer the direct, mechanical feel of hydraulic systems, especially on:
- Uneven roads
- Farm or construction sites
- High-speed highway driving
Electric steering, especially earlier versions, was sometimes criticized for feeling too light or disconnected.
3. Engine-Driven Simplicity
Hydraulic systems are mechanically simple:
- No control modules
- No electric motors
- No need for firmware updates
For heavy-duty owners, this meant easier field repairs and lower cost maintenance.
Advantages of Hydraulic Power Steering on the 2015 Ram
Although EPS is more common today, the traditional hydraulic system on the 2015 Ram still has several strengths:
Consistent Steering Feel
Hydraulic pumps provide the same assistance at any speed, giving a natural and stable steering sensation.
Strong Performance at Low Speeds
When maneuvering trailers, parking, or driving off-road, hydraulic assist delivers powerful force with minimal steering resistance.
Easy to Repair
Most general mechanics can:
- Replace hoses
- Repair pumps
- Flush fluid
Parts are widely available and affordable.
Proven Durability
Hydraulic steering has been used for decades in trucks and commercial vehicles, making it a trusted and predictable design.
Downsides of Hydraulic Steering Compared to Electric
Of course, compared to modern EPS systems, the hydraulic setup on the 2015 Ram has a few disadvantages:
Slight Fuel Loss
Because the power steering pump is always engine-driven, it uses energy even when the wheel is not turning. EPS reduces fuel demand because it only draws power when needed.
More Maintenance
Hydraulic systems require:
- Fluid changes
- Hose inspections
- Leak repairs
EPS avoids these issues.
No Software-Based Assist Features
Modern electric systems enable advanced features like:
- Lane keep steering assist
- Automatic parking
- Steering-based traction adjustments
The 2015 Ram’s hydraulic system does not support them.
How the 2015 Ram 5.7 Steering System Works
The system operates using hydraulic pressure generated by an engine-mounted pump. The basic components include:
- Steering wheel
- Steering gearbox or rack
- Power steering pump
- Fluid reservoir
- Hydraulic hoses
- Steering knuckles
When the driver turns the wheel:
- The pump sends pressurized fluid into the steering assembly.
- The pressure multiplies the driver’s input force.
- Wheels turn with reduced effort.
Since the pump is belt-driven, engine speed directly affects the steering assist. At idle, assistance is slightly lower; at driving speeds, steering becomes lighter.
How to Identify the Type of Steering on Your 2015 Ram
If someone is unsure which system their truck uses, these clues help confirm:
Check Under the Hood
If you see:
- A power steering fluid reservoir
- Belt-driven pump
- Hydraulic hoses
then the truck has hydraulic assist.
Look for Warning Labels
Some trucks include service information on the fan shroud or underhood sticker.
Check the VIN Service Breakdown
A dealership can decode factory steering specifications from the truck’s VIN.
Inspect the Rack
Hydraulic racks have two fluid lines entering the assembly; EPS units do not.
Can You Convert a 2015 Ram 5.7 to Electric Power Steering?
Yes—conversion is possible, but it is not a simple bolt-on swap. Some owners attempt EPS conversions for engine swaps, custom builds, or to reduce parasitic load.
Possible approaches include:
1. Adding an Electric Steering Column Assist Motor
Several aftermarket systems install between:
- Steering wheel
- Steering shaft
They provide electronic assist without changing the hydraulic rack. These systems are often used in:
- Hot rods
- EV conversions
- Off-road buggies
2. Full EPS Rack and Column Conversion
A complete system swap requires:
- EPS rack
- Wiring
- Control modules
- ECU integration
This is complex and usually expensive.
3. Modified Hydraulic-Electric Pump
Some builders replace the belt-driven pump with an electrically driven hydraulic pump. This preserves the hydraulic rack while eliminating engine load.
Is Conversion Worth It?
For most owners, keeping the original hydraulic system is simpler and more economical, especially if the truck is used for:
- Work
- Towing
- Heavy off-road duty
However, conversion might make sense for:
- Engine swaps
- EV conversions
- Drag racing
- Projects where every horsepower counts
Maintenance Tips for the 2015 Ram Power Steering System
To ensure reliable operation:
Check Fluid Level Regularly
Low fluid causes:
- Whining noises
- Heavy steering
- Increased pump wear
Inspect Hoses for Leaks
Cracked hoses are a common problem in older trucks.
Flush Fluid Every 50,000–80,000 Miles
Fresh fluid protects the pump and rack seals.
Listen for Pump Noise
A loud or grinding pump means the system is overloaded or low on fluid.
Check Belt Tension
A worn belt reduces pump output and steering performance.
Conclusion
So, does the 2015 Ram 1500 5.7 4×4 have electric power steering?
No. It uses a conventional hydraulic power steering system.
This design was chosen for towing strength, durability, and consistent driving feel. While electric conversions are possible, the original hydraulic system remains reliable, easy to service, and well-suited to the truck’s work-oriented purpose.
For owners maintaining or upgrading their 2015 Ram, knowing the steering system helps ensure the right parts, tools, and service decisions—whether keeping the truck stock or building something unique.
