What are the reasons for the abnormal noise symptoms in the Focus steering gear?

Here are the specific reasons for the abnormal noise symptoms in the Focus steering gear: 1. Aging of the steering tie rod ball joint: There is play, and it is necessary to replace the steering tie rod ball joint and perform a four-wheel alignment. 2. Oil leakage in the machine dust cover direction: The dust cover needs to be replaced or re-greased. 3. Steering gear failure: It may be due to excessive clearance between the steering gear and the gear, requiring replacement of the steering gear. 4. Improper tension or aging of the power steering belt: The belt tension needs to be adjusted or the belt replaced. Below is extended information on the symptoms of steering gear damage: 1. Difficulty in steering wheel return: Generally, vehicle steering wheels have an automatic return function. In cars equipped with hydraulic power steering gears, the automatic return function is somewhat weakened due to hydraulic damping. If the return speed is too slow, it indicates a fault in the return function, which usually occurs in the steering mechanical parts. 2. Steering wheel shaking or deviation: Cars driving on one side of a curved road naturally have a tendency to deviate, and the deviation is more obvious when the curve is large. After ruling out tire pressure issues, the problem may be due to loosening or breakage of a mechanical component in the steering gear. 3. Uneven steering wheel resistance: When turning the steering wheel, one side feels light and easy while the other side feels heavy. This symptom is generally caused by leakage of the seal responsible for sealing one side of the high-pressure chamber, or it could be due to improper adjustment of the steering limit valve.
When I first drove my Focus, I encountered steering gear noise, which was really annoying, like a creaking friction sound, especially more noticeable when turning. I think the problem mostly lies in the aging of steering system components, such as wear on the ball joints of the tie rods, because prolonged driving on bumpy roads can loosen metal parts, causing noise. Also, the dust cover might be broken, allowing dust to get in and grind the gears, or the power steering fluid might be low or too dirty, causing the hydraulic pump to work inefficiently. I tried adding fluid, which helped a bit but didn't solve the problem completely. Later, I went to a repair shop and replaced the parts to fix it. Additionally, issues with tires and suspension can also transmit noise, so regular checks are necessary. Although steering noise may seem minor, not fixing it can affect handling stability, especially when turning, posing significant risks. I recommend paying attention to such maintenance details and not waiting until something goes wrong to regret it.
As a seasoned driver with ten years of experience, I've dealt with numerous cases of Focus steering gear noise. The main causes are often aging steering components: loose ball joints, worn tie rods, or damaged bearings inside the steering gear. Dust accumulation or insufficient fluid can exacerbate the issue. Another scenario is improper assembly, such as loose screws or displaced parts. My advice is to conduct a self-check after parking: turn the steering wheel to locate the noise source; if there's a squeaking sound, first check the fluid level and dust boots. If the fluid is cloudy, replace it—this can resolve most issues. Delaying repairs may lead to sluggish or even stuck steering, which is dangerous at high speeds. DIY repairs can save money for those with mechanical skills, but professional shops offer more reliable solutions. Remember, minor noises can signal major risks—early inspection ensures peace of mind and maintains driving quality.
