Steering is a primary control system. If response is delayed, inconsistent, or noisy, the vehicle is no longer operating safely. At 8 Cylinders Auto Repair in Philadelphia, we diagnose and repair steering systems using mechanical inspection and hydraulic/electronic testing.
How Modern Steering Systems Work
The steering system translates driver input at the wheel into directional movement of the front tires. Most vehicles use power assistance to reduce effort.
There are two primary steering designs:
Rack-and-Pinion Steering
- Most common in modern vehicles
- Steering wheel turns a shaft
- Shaft rotates a pinion gear
- Pinion moves the steering rack left or right
- Rack moves tie rods, which turn the wheels
Steering Box (Recirculating Ball) System
- Common in larger trucks and older vehicles
- Steering wheel turns a worm gear
- Worm gear moves a sector shaft
- Sector shaft controls steering linkage
Power assist is provided either by:
- Hydraulic power steering (uses pressurized power steering fluid)
- Electronic power steering (EPS) (uses an electric motor)
Hydraulic systems require clean fluid and sealed lines. Contamination or leaks lead to pressure loss and failure.
Signs Your Steering System Needs Repair
If you experience any of the following, inspection is required:
- Difficulty turning the steering wheel
- Steering wheel vibration
- Vehicle pulling to one side
- Grinding or screeching while turning
- Power steering fluid leak under vehicle
- Steering feels overly stiff or unusually loose
- Steering wheel slips or does not return properly
Delaying repair increases wear on tie rods, ball joints, and suspension components. Estimated probability of secondary component damage after prolonged fluid leak: 50–70%.
Common Steering Repairs We Perform
- Power steering rack and pinion replacement
- Steering box repair
- Tie rod replacement
- Power steering pump replacement
- Power steering fluid exchange
- Hydraulic line repair
- Electronic steering system diagnostics
We identify the failure point before replacing major components. Fluid leaks, worn seals, or belt issues can mimic rack failure.
Why Steering Fluid Service Matters
Hydraulic steering systems rely on clean, pressurized fluid. Over time:
- Fluid degrades
- Debris accumulates
- Seals wear
- Internal corrosion develops
Routine fluid exchange reduces wear and extends component life.
Service for All Major Brands
We repair steering systems on domestic and foreign vehicles including Audi, BMW, Honda, and Toyota.

Frequently Asked Questions (FAQ)
Can I drive with a power steering leak?
Temporarily, but fluid loss can cause pump failure and steering lockup.
Is steering stiffness always a rack problem?
No. It may be fluid-related, pump failure, belt slippage, or electronic assist malfunction.
How long does rack and pinion replacement take?
Typically 3–6 hours depending on vehicle design.
Does steering repair require alignment?
Yes. After rack or tie rod replacement, wheel alignment is necessary.
Is electronic power steering more reliable?
It eliminates hydraulic leaks but introduces electronic failure points.
Steering issues do not resolve on their own. If handling feels unstable or effort changes unexpectedly, schedule a diagnostic inspection at 8 Cylinders Auto Repair in Philadelphia before the problem escalates.
