What Causes the Steering Column Noise in Highlander?
3 Answers
Introduction to the causes of steering column noise in Highlander: 1. Lack of Lubrication: If you hear noise coming from below the steering wheel while turning, check the steering column dust cover. A lack of lubrication in the dust cover can cause dry friction noise. Applying some grease inside the dust cover will eliminate this noise. 2. Normal Noise: If the noise occurs only when turning the steering wheel after activating the turn signal, it is likely the sound from the turn signal auto-return mechanism's snap-back clip. This sound is normal. When turning the steering wheel, you may hear a "click" sound, and three such sounds will occur per full rotation of the steering wheel. This is because there are three auto-return positions per rotation of the steering column. The noise will disappear once the turn signal is turned off.
The steering column noise in the Highlander is quite annoying, and I often think about it. Common causes of the noise include wear and tear of the steering column bearing: after prolonged use, the lubricant inside the bearing dries up or dust gets in, causing a squeaking sound when turning. Another reason is loose connecting parts, such as screws securing the steering column, which become more noticeable on bumpy roads. Wear and tear of the internal bushings or joints in the steering column can also cause noise due to increased friction. If the Highlander has an electric power steering system, internal motor or gear failures can produce a humming sound. If left unrepaired, steering may become heavier or even jam, increasing the risk of handling. I recommend first checking while parked: turn the steering wheel after turning off the engine to locate the sound, and try tightening visible screws. If the issue is unclear, take it to a professional shop for inspection. Regular maintenance and lubrication can extend the lifespan of the parts. Given the Highlander's heavy body and significant steering load, regular maintenance is crucial.
As a long-time Highlander owner, I've personally experienced steering column noise issues. There was a clicking sound when turning, which I initially thought was minor, but it turned out to be insufficient lubrication and wear in the steering column bearings. Also, loose universal joints connecting the steering wheel or steering gear can cause noticeable noises at low speeds. In electric models, power assist module failures can create louder noises and affect steering smoothness. If left unaddressed, worsening wear may lead to steering failure, which is quite unsettling while driving. I've found that regular dust cleaning and lubrication can prevent some of these issues. While the Highlander is reliably designed, never ignore any unusual noises; always test the steering wheel with a few turns before driving and postpone trips if anything feels abnormal. Getting it checked at a reputable repair shop isn't costly, and replacing parts will restore quiet operation. Vehicle maintenance lies in the details - address minor issues promptly to avoid major troubles.
