A bad steering rack can make driving unsafe, causing issues like loose steering, vibrations, and fluid leaks. If left unchecked, it may lead to complete steering failure. For mechanics and auto parts dealers, understanding bad steering rack symptoms is crucial for providing the best service to customers. Let’s dive into the 7 most common signs of a failing steering rack and what to do about them.
What Are the Bad Steering Rack Symptoms?
Dead Spot in Steering (Unresponsive Steering Wheel)
Symptom:
The steering wheel has a “loose” or “numb” spot where it doesn’t respond.
You turn the wheel slightly, but the car doesn’t change direction immediately.
Causes:
Worn-out internal components of the steering rack.
Excessive play in the tie rods or pinion gears.
Fix:
Check for excessive play in the steering mechanism.
Tighten or replace loose components inside the rack and pinion system.
Steering Becomes Stiff or Inconsistent
Symptom:
Turning the wheel is harder than usual, especially at low speeds.
The steering feels “sticky” or changes from light to heavy randomly.
Causes:
Low or contaminated power steering fluid.
A failing power steering pump.
Internal blockages inside the steering rack.
Fix:
Check and replace the power steering fluid if necessary.
Inspect the power steering pump and rack for damage.
Unusual Noises When Turning
Symptom:
Clunking – A dull knocking sound when turning.
Whining – A high-pitched sound, especially at low speeds.
Grinding – A rough, metallic noise when moving the wheel.
Causes:
Loose or worn-out bushings inside the steering rack.
Low power steering fluid causing pump strain.
Damage to the internal gears of the rack and pinion.
Fix: Tighten and lubricate any loose parts while replacing damaged bushings or fluid seals as needed.
Steering Wheel Vibration
Symptom:
The steering wheel shakes, especially when turning.
Vibrations get worse at higher speeds or during sharp turns.
Causes:
Internal steering rack wear causes uneven resistance.
Loose or worn-out tie rods in vehicle suspension parts.
Fix: Check for steering rack leaks or mechanical issues while inspecting and replacing worn tie rods as needed.
Vehicle Pulling to One Side
Symptom:
The car drifts left or right, even when you’re not turning.
The steering feels uneven, requiring constant correction.
Causes: Steering issues can result from a misaligned steering rack, unbalanced hydraulic pressure in the power steering system, or worn tie rods and ball joints.
Fix: Get a wheel alignment and check your power steering fluid levels to keep your steering smooth and responsive.
Power Steering Fluid Leak
Symptom: Red or brown fluid puddles under the car.
Cause: Cracked hoses, worn-out seals, or damaged pump connections.
Fix: Locate the leak, replace faulty hoses, and refill with fresh power steering fluid.
Uneven Tire Wear
Symptom: Tires wear out faster on one side than the other.
Cause: Excessive play in the steering rack causing misalignment.
Fix: You’ll need to rotate the system and balance the car’s tires on a regular basis, as well as check the steering components for excessive wear.
What Causes Steering Rack Damage?
- Potholes & Road Impact – Sudden shocks can damage internal components.
- Lack of Maintenance – Old power steering fluid can cause internal wear.
- Poor Driving Habits – Aggressive turning and excessive force on the wheel.
How to Prevent Steering Rack Failure?
- Regularly check and change the power steering fluid.
- Avoid hitting potholes and curbs at high speeds.
- Get a professional steering inspection every 10,000 miles.
