Chrysler 300 Power Steering Hoses

Chrysler 300 Power steering hoses

Starting at $66.95, AutoBuffy carries 4 power steering hoses from Gates and Mopar to fit your Chrysler 300. The power steering hose carries pressurized fluid between the pump and steering gear, making low-effort steering possible. A cracked, leaking, or collapsed hose causes fluid loss and pump damage, so replacement is urgent once a leak is spotted.

Signs your Chrysler 300 needs a new power steering hose

  • Power steering fluid puddle or wet spot underneath the front of the vehicle, often reddish or amber in color
  • Whining or groaning noise from the steering pump that worsens when turning the wheel
  • Stiff, heavy, or jerky steering effort, especially at low speeds or when parking
  • Visible oily residue or soaking along the hose itself, at fittings, or on nearby suspension components
  • Steering fluid reservoir runs low repeatedly even after topping it off
  • Burning smell near the engine bay caused by fluid dripping onto hot exhaust components

Which power steering hose should you buy for your Chrysler 300?

Power steering systems use two distinct hoses — a high-pressure hose (pump to steering gear) and a low-pressure return hose (gear back to reservoir) — and they are not interchangeable. Confirm which line is leaking before ordering, then choose between an OE-equivalent replacement and an upgraded option based on your budget and how long you plan to keep the vehicle.

OE-Equivalent High-Pressure Hose
Best for
Most drivers doing a direct like-for-like repair
What you get
Pre-formed steel-reinforced hose with factory-spec fittings; bolts on with no modification
OE-Equivalent Return (Low-Pressure) Hose
Best for
Replacing the softer, return-side line that collapses or cracks with age
What you get
Rubber or nylon hose rated for return-line pressures; cut-to-length or pre-cut versions available
Premium / Stainless-Braided Hose
Best for
High-mileage vehicles or owners wanting longer service life
What you get
Stainless braid over PTFE liner resists heat, abrasion, and pressure spikes better than standard rubber
Complete Hose Assembly Kit
Best for
Anyone replacing both lines at once or doing a full steering service
What you get
Matched high- and low-pressure hoses sold together; saves labor time and ensures both sides are fresh

Replacing power steering hoses on a Chrysler 300

Moderate⏱ 1–2 hoursFlare-nut (line) wrenches in common sizesDrain pan and shop ragsHose clamp pliers or flat-head screwdriverTurkey baster or fluid transfer pump for reservoir evacuationFunnel and fresh power steering fluid

Drain as much fluid from the reservoir as possible before loosening any fittings to minimize spillage, then use flare-nut wrenches on threaded fittings to avoid rounding them. Route the new hose exactly as the original to keep it clear of hot and moving components, and snug fittings firmly without over-tightening. After installation, refill the reservoir, start the engine, cycle the steering wheel slowly lock-to-lock several times to bleed air, and recheck the fluid level before driving.

Frequently asked questions

How much does it cost to replace power steering hoses on a Chrysler 300?
Parts start at $66.95 at AutoBuffy. The total repair cost depends on whether you replace one hose or both and whether you do it yourself or use a shop. DIY saves the most; a shop will add one to two hours of labor on top of the part cost, which can make the total significantly higher.
Can I drive my Chrysler 300 with a leaking power steering hose?
Driving with a leaking power steering hose is not recommended. Even a slow leak will eventually drain the reservoir, starving the pump of fluid. Running a power steering pump dry can destroy it within minutes, turning a relatively inexpensive hose replacement into a much costlier pump and hose job.
How do I tell if the high-pressure or low-pressure hose is leaking on my Chrysler 300?
Trace the wet trail back to its source with the engine off and a clean rag. The high-pressure hose runs from the pump outlet to the steering gear and typically has a rigid metal section with threaded fittings. The return hose is softer, larger in diameter, and runs from the gear back to the reservoir. Leaks at crimp fittings usually indicate the high-pressure side.
How long does a power steering hose last?
Power steering hoses typically last somewhere between 75,000 and 150,000 miles, but heat, ozone exposure, and power steering fluid condition all accelerate aging. Inspect hoses during oil changes for cracking, swelling, or soft spots. Vehicles in hot climates or with a history of overheating tend to see hose failures on the shorter end of that range.
Do I need to flush the power steering system when replacing a hose on my Chrysler 300?
Flushing is strongly recommended any time you open the power steering system. Old fluid is often contaminated with rubber particles from degrading hose liners, and those particles accelerate pump and rack wear. Flush with fresh fluid approved for your system, cycle the steering lock-to-lock several times, and check the reservoir level before calling the job done.
Will a universal power steering hose fit my Chrysler 300?
Universal hoses can work for the low-pressure return line, where you cut to length and use reusable clamps, but they are not suitable for the high-pressure line. High-pressure hoses require exact-fit fittings and pressure ratings matched to your specific system. Using a universal hose on the high-pressure side risks fitting failure and a sudden loss of steering assist.
