Why does the Audi Q5 steering wheel make a friction sound when turning?

[Jameson]

q5 steering wheel friction sound may be due to aging steering gear, loose steering wheel, or installation issues. Below are related solutions for stiff steering: Insufficient power steering fluid: Normally, the steering effort feels relatively constant. If it suddenly becomes heavy one day or gradually increases in resistance, it could be due to dirty power steering fluid—similar to engine oil—requiring replacement. Alternatively, if there's a fluid leak causing low levels, the power assistance decreases, making the steering wheel heavier. This situation requires timely maintenance or replenishment/replacement of power steering fluid. Low tire pressure: Insufficient tire pressure increases the contact area between the tire and the road surface, raising friction and making steering more difficult, resulting in a heavy steering wheel. This is unsafe for driving and should be addressed by promptly refilling the tires. Overly tight bearing fit: For the rolling bearings in the steering system linkage, if they are fitted too tightly with sliding bearings, it can hinder proper lubrication and operation, leading to sticking and a heavier steering wheel. In this case, inspect the mechanical components and power assistance system, or check for oil leaks and damaged intake seal components.

I've also encountered the issue of steering wheel friction noise several times while driving my Audi Q5. This typically occurs due to unnecessary friction generated by components in the steering system during rotation. The most common causes include worn connecting parts or bearings in the steering column, or abnormal noises from the power steering motor during operation. Sometimes, insufficient lubrication or dust accumulation can amplify the sound. I recommend first checking if lubricant needs to be added. If the noise only occurs during certain turns, the tie rod might be loose. Don't underestimate this issue, as loss of steering control could increase accident risks. It's best to visit a professional repair shop as soon as possible, where technicians will use diagnostic tools to identify the specific components. Regular maintenance of the steering system can extend its lifespan and prevent such troubles. I personally delayed addressing it for a few days, which made the steering heavier and cost me several hundred dollars in repairs to fix.
