A brand-new steering rack costs hundreds or even thousands of dollars, and remanufactured steering gear also requires extra maintenance budgets. Most steering rack damages are not caused by factory defects, but by bad daily driving habits. Many drivers unconsciously damage their steering systems while driving, leading to oil leaks, stiff steering, abnormal noise and premature rack failure.
You do not need professional repair skills to protect your steering rack. Follow these 6 simple daily driving habits, and you can double the service life of your HPS, EHPS or EPS steering rack, cut auto repair costs, and keep safe steering performance.
Habit 1: Avoid Holding Full Steering Lock for a Long Time
It is the most common mistake most drivers make: turning the steering wheel all the way left or right and holding the full-lock position when parking or reversing.
For HPS and EHPS hydraulic steering racks: Fully turning the wheel will maximize internal hydraulic pressure. Sustained high pressure squeezes internal oil seals and aging rubber parts, which is the top cause of steering fluid leakage.
For EPS electric steering racks: Long-time full lock increases extra load on the assist motor and steering shaft, triggering motor overheating and accelerated sensor aging.
Suggestion: Do not hold the full steering lock over 3 seconds. If you need maximum turning angle, release the steering wheel slightly after turning to reduce internal pressure.
Habit 2: Never Hit Potholes or Curbs at High Speed
The steering rack, tie rods and ball joints are precision components. When driving at high speed, hitting road potholes, speed bumps, roadside curbs or stone barriers will deliver huge instant impact to the whole steering assembly.
This violent impact will bend the internal rack gear, deform tie rods, crack rack boots, and even cause invisible steering shaft damage. Many sudden steering deviation and loose steering problems are caused by road impact instead of part aging.
Suggestion: Slow down in bumpy roads, urban road depressions and parking lots. Avoid hitting curbs directly when parking, especially for sedan and compact SUV with low chassis.
Habit 3: Inspect Steering Rack Boots Regularly
Steering rack boots are cheap rubber sleeves, but they are the first protective barrier of the whole steering system. Many drivers ignore this tiny part, which leads to irreversible steering rack damage.
Once the rubber boot cracks, tears or falls off, road dust, sand, rainwater and muddy water will penetrate into the steering rack interior. The internal precision gear and metal shaft will rust and wear rapidly. For hydraulic steering, water contamination will deteriorate power steering fluid and cause severe oil leakage.
Suggestion: Check rack boots every 6 months. Observe cracks, aging, oil seepage and tearing. Replace damaged boots in time with low cost, which can save expensive steering rack replacement cost later.
Habit 4: Replace Power Steering Fluid On Time (For HPS & EHPS)
This maintenance rule only applies to hydraulic and electro-hydraulic steering systems. Dirty, oxidized, expired power steering fluid is the silent killer of HPS and EHPS steering racks.
Long-term unchanged steering fluid will produce metal scraps and sediment. These tiny impurities will scratch internal seals and gear walls during circulation. It will result in gradual oil leakage, heavy steering and abnormal friction noise. Wrong type of steering fluid will also corrode internal rubber seals and accelerate part failure.
Suggestion: Replace power steering fluid every 40,000 to 60,000 miles. Use manufacturer-recommended fluid specification, never mix different types of steering oil.
Habit 5: Avoid Overloading Your Vehicle
Excessive vehicle weight brings extra burden to front suspension and steering system. Heavy cargo will cause front wheel pressure deviation, increase rack bearing load, and aggravate unilateral gear wear.
This habit does the greatest harm to pickup trucks and large SUVs. Long-time overloading will cause permanent steering rack deformation and irreversible steering pull fault.
Habit 6: Warm Up Steering System in Cold Weather
In cold winter, low temperature hardens rubber seals and thickens hydraulic steering fluid. Driving and turning sharply immediately after starting the car will increase steering resistance, tear aging seals and damage EPS assist motors.
Suggestion: Warm up the engine for 30 seconds to 1 minute in freezing weather. Turn the steering wheel slightly left and right several times to activate the whole steering system before formal driving.
Bonus: Early Warning Signs of Worn Steering Rack
-
Visible oil stains on steering rack boots
-
Clunking noise when turning at low speed
-
Steering wheel fails to return to center automatically
-
Vehicle slightly pulls to one side while driving straight
Final Thoughts
Expensive steering rack damage mostly comes from daily bad driving behaviors, instead of product quality problems. Controlling driving habits, checking protective boots and doing regular fluid maintenance can greatly extend steering rack service life, whether you use rack-and-pinion or recirculating ball, HPS or EPS steering systems.
If your steering rack suffers from oil leakage, abnormal noise or aging failure, shop our high-quality new and remanufactured steering racks. All parts fit sedans, SUVs and pickups perfectly, with strict quality inspection and long service life.
